Assassin’s Creed Black Flag Resynced: Early PC Review Finds No Major Stutter

Ubisoft has given Overclock3D early access to Assassin’s Creed Black Flag Resynced, a from-the-ground-up remake of 2013’s Assassin’s Creed 4: Black Flag that uses the latest Anvil Engine foundation and, according to the outlet’s PC performance review, largely avoids major stutters. That matters because the modern PC version of a beloved open-world game lives or dies not just on sharper assets, but on whether it can sail through traversal, shader compilation, and GPU scaling without the familiar hitching that has dogged too many recent releases. The early verdict is cautiously encouraging: Resynced appears to be a technological rebuild rather than a superficial remaster, and its first PC performance signals are stronger than the remake-skeptical market might have expected.

The most important detail in Overclock3D’s report is not that Assassin’s Creed Black Flag Resynced looks better, or that combat has been refined, or that new content is available. It is that Ubisoft is describing this as a from-the-ground-up remake with almost no code inherited from the game’s original incarnation. In PC performance terms, that is the difference between renovating an old engine room and replacing the vessel beneath the player entirely.
The original point of comparison is 2013’s Assassin’s Creed 4: Black Flag, a game from a very different PC era. That was the age of slower storage assumptions, lower-resolution asset targets, less aggressive temporal reconstruction, and a multiplatform pipeline built around hardware constraints that no longer define the current Windows gaming market. A straightforward remaster could have preserved many of those assumptions while improving textures and lighting around them; Resynced, according to the supplied review material, instead moves the experience onto Ubisoft’s latest incarnation of its Anvil Engine.
That engine detail is not cosmetic. Overclock3D notes that Resynced shares technological underpinnings with Assassin’s Creed Shadows, meaning Ubisoft is not simply modernizing Black Flag in isolation. It is placing the remake within the company’s current rendering, streaming, and asset-management stack — the same broad family of technology used for its newest Assassin’s Creed work.
The practical consequence is twofold. First, Resynced should be judged less like a texture-pack update and more like a new PC release wearing a familiar narrative coat. Second, its performance behavior tells us something about Ubisoft’s current PC engineering priorities, especially around shader handling, traversal stability, and how much work the company is willing to do before the player ever reaches the main menu.

The Stutter Story Is the Real Review​

Overclock3D frames the central question bluntly: does it stutter? That is the correct question for a 2020s PC performance review, because average frame rate has become a misleading comfort metric. A game can benchmark well and still feel broken if shader compilation, asset streaming, or traversal events interrupt motion at the wrong moments.
The review’s answer is unusually positive. According to Overclock3D, Assassin’s Creed Black Flag Resynced runs without major stutters, and the shader precompilation step completes quickly when the game first boots. During gameplay, the outlet says PC gamers can expect an almost stutter-free experience, provided they choose appropriate graphical settings.
That last condition is doing real work. “Almost stutter-free” is not the same as universally flawless, and “with the right graphical settings” implies that the game still needs to be matched intelligently to hardware. But in the current PC market, where high-profile releases have trained players to dread the first thirty minutes of shader hitching, a quick precompilation step and stable traversal behavior are not minor amenities. They are the foundation of trust.
The reason shader behavior matters so much is that modern PC games must handle a huge matrix of GPUs, drivers, resolutions, and graphics options. When compilation happens lazily during gameplay, the player pays for it as a visible hitch. When compilation is performed up front, the game asks for patience once rather than stealing smoothness repeatedly during play.
Overclock3D’s report suggests Ubisoft has chosen the latter path effectively here. If that holds across broader public hardware configurations, Resynced could become a useful example of the right compromise: do the technical housekeeping early, make it quick enough that players do not revolt, and then keep the open world moving.

A Remake With Shadows-Era Expectations​

The connection to Assassin’s Creed Shadows raises expectations as much as it explains them. A remake built on the same technological underpinnings as a modern mainline Assassin’s Creed game cannot hide behind nostalgia when it comes to PC behavior. Players will expect current-generation rendering features, flexible settings, competent upscaler support, and sane VRAM scaling.
Overclock3D says its review tests a wide range of GPUs and examines VRAM usage, graphical settings, and supported upscalers in depth. The excerpted source material does not provide the numerical results of those pages, so the important point for now is the review’s scope rather than any claimed ranking. This was not presented as a vibes-based hands-on; it was framed as a PC performance review built around the areas that actually break modern releases.
That scope is appropriate because Resynced sits in a tricky category. It is a remake of a game many players remember as expansive and atmospheric, but it is also a new PC product using a current engine. Players with older systems may assume that a remake of a 2013 game should be easy to run, while players with newer systems may expect it to behave like a contemporary prestige release.
Both assumptions can be wrong. A from-the-ground-up remake can demand modern GPU resources even when its source material is old, because the remake is not rendering the old game. It is rendering new assets, new lighting, new effects, and a new engine interpretation of the same world.
That is why the “almost no code” claim matters so much. It indicates that performance should not be understood through the lens of the old game’s requirements or quirks. Resynced is not necessarily constrained by the original’s bottlenecks, but it also does not inherit the original’s lightness.

The table tells the strategic story. Ubisoft is selling continuity of theme, setting, and identity, but the PC performance question belongs to the new technology stack. That is where Resynced will either justify its existence or become another case study in remake excess.

The Driver Baseline Is Narrow but Useful​

Overclock3D’s test environment used AMD Software 26.6.4 and Nvidia’s GeForce 610.74 driver for Windows 10/11. Those driver names are more than housekeeping details. They set the boundary for the outlet’s early claims and remind readers that PC performance is always a three-way negotiation between the game, the operating system, and the GPU driver.
For WindowsForum readers, the Windows 10/11 driver framing is especially relevant. Resynced is being discussed as a Windows PC release in a market where many players are split between mature Windows 10 installations and newer Windows 11 gaming rigs. Driver maturity, scheduling behavior, security defaults, and background services can all influence the subjective experience even when the same GPU is installed.
The source material does not claim that one operating system performs better than the other, and it would be irresponsible to invent that conclusion. What it does show is that the review’s GPU driver baseline explicitly covered current Windows 10/11 driver packages from AMD and Nvidia at the time of testing. That makes the stutter claims more meaningful than if they were based on an outdated driver stack.
Still, early-access driver testing has natural limits. GPU vendors often ship game-ready updates closer to public release windows, and developers may make last-mile patches after media testing begins. The version numbers in Overclock3D’s review are a snapshot, not a permanent map of the game’s future performance profile.
That caveat cuts both ways. Public builds can improve after early reviews, especially when vendor profiles are updated. They can also regress if a launch patch changes streaming, anti-tamper behavior, graphics defaults, or asset packaging. The encouraging news is that the core symptom Overclock3D highlights — the lack of major stutters — is usually not produced by accident.

“Right Settings” Is Doing More Work Than Marketing Admits​

The sentence that deserves the most attention is the least glamorous one: if you play the game with the right graphical settings, you should have a smooth experience. That is a reasonable statement, but it is also the modern PC gaming contract in miniature. The game will behave if the player, the hardware, and the settings menu reach a truce.
This is where many performance discussions become dishonest. Players want a binary answer — optimized or not optimized — but modern games exist on a curve. Texture quality can become a VRAM problem before it becomes a shader problem. Resolution scaling can rescue frame rate while leaving CPU-bound traversal untouched. Upscalers can make an ambitious preset viable, but they cannot always fix poor frame pacing.
Overclock3D’s review reportedly tests VRAM usage, graphical settings, and supported upscalers in depth, which is exactly where a serious PC assessment should go after stutter. A wide range of GPU testing tells readers whether the game scales. VRAM testing tells them where visual ambition starts to collide with memory reality. Upscaler testing tells them whether the game has modern escape hatches for higher resolutions or weaker hardware.
The provided source excerpt does not list specific supported upscalers, so any attempt to name them would overstate the record. But the mere inclusion of upscaler testing in the review scope is telling. Ubisoft and PC outlets alike understand that reconstruction technologies are no longer bonus features for enthusiasts; they are part of the default performance conversation.
The “right settings” caveat should also temper expectations around remake comparisons. If Resynced looks substantially better than the original, it may also require more disciplined configuration. The fair question is not whether a new remake runs like a 2013 game. The fair question is whether it runs predictably, exposes enough settings to match different systems, and avoids pathological behavior such as unavoidable shader hitches.
On that front, Overclock3D’s early-access impression is more promising than the genre average. A game that asks users to tune settings is normal. A game that stutters regardless of settings is the real offender.

The Open-World Stress Test Is Traversal, Not Combat​

Combat refinements matter to the player experience, and the source material says combat has been refined. But for PC performance, combat is rarely the only or even the primary danger zone in an open-world Assassin’s Creed game. Traversal is where the engine has to stream assets, maintain animation continuity, manage visibility changes, and keep simulation moving while the player crosses dense environments.
That is why Overclock3D’s emphasis on shader compilation and traversal stutter is so important. The review explicitly places Resynced in the context of modern PC releases plagued by shader compilation stutter and traversal stutters. It even notes that this has been especially true of some Unreal Engine 5 games, before saying Ubisoft has done a great job here.
The engine comparison should not be misread as a blanket condemnation of another engine or a guarantee about Anvil. The more useful lesson is that engine defaults, developer discipline, and platform-specific QA all matter. A powerful engine can still produce a bad PC release if shader handling and asset streaming are not managed carefully.
Resynced’s reported smoothness suggests Ubisoft has paid attention to those failure modes. If shader precompilation completes quickly at first boot and gameplay is almost stutter-free, then the player’s experience is being protected at two critical points: startup and movement. That is precisely where open-world games most often reveal whether their PC version was treated as a first-class platform or a late porting target.
The maritime setting associated with Black Flag also makes this more important, even without relying on details beyond the source. A remake of this particular Assassin’s Creed entry has to preserve a sense of movement and continuity. Few things puncture atmosphere faster than a hitch at the moment the world is supposed to feel expansive.

New Content Raises the Performance Burden​

The source material says new content is now available, the story has been refined, graphics have been improved, and combat has been refined. Those are the familiar bullet points of a remake pitch, but they also expand the test surface. Every new mission, asset set, animation path, and environment variant is another opportunity for uneven performance.
That is the hidden cost of a from-the-ground-up remake. The developer is not merely increasing resolution and calling it a day. It is re-authoring or reimplementing enough of the experience that old assumptions about where the demanding scenes are may no longer apply. A quiet area in the original could become heavier in the remake; a once-simple encounter could include new effects, geometry, or animation logic.
Overclock3D’s claim that the game runs without major stutters is therefore more valuable than a narrow benchmark would be. Frame-rate averages taken from a single repeatable run can miss the messiness of a rebuilt open world. Stutter observations, while more subjective if not supported by frame-time graphs, capture the kind of interruption players actually notice.
The limitation is that we do not yet have the detailed pages of the review in the provided material. We know the outlet planned or conducted testing across a wide range of GPUs and examined VRAM usage, settings, and upscalers, but the excerpt does not give the full spread of results. That means the responsible reading is confidence in the general smoothness claim, not certainty about how every GPU tier will behave.
For buyers, this distinction matters. A game can be broadly smooth and still require compromises on midrange or older hardware. A game can avoid shader stutter and still exceed a GPU’s memory comfort zone at high settings. A game can support upscalers and still need careful tuning to avoid a soft or unstable image.
Resynced, on the evidence available, appears to have cleared the most visible PC performance hazard. The remaining question is how gracefully it scales once ordinary players bring ordinary Windows systems into the equation.

Why This Matters Beyond One Remake​

The PC market has become less forgiving of technically sloppy launches, and rightly so. Players have absorbed years of releases that arrived with day-one patches, shader compilation pauses, inconsistent frame pacing, and settings menus that offered dozens of toggles without explaining the real bottlenecks. In that environment, a remake that reportedly front-loads shader work and avoids major stutter is not just doing well; it is refusing to repeat the industry’s most annoying mistake.
This matters especially for Ubisoft because the Assassin’s Creed franchise is built around movement through dense, visually rich spaces. If the engine cannot keep up with that fantasy, the brand’s promise collapses. A pirate-era remake can improve graphics and story all it wants, but the PC version still has to make motion feel continuous.
The Resynced report also complicates the easy cynicism around remakes. Players often suspect that remakes exist to monetize nostalgia with limited technical ambition. A from-the-ground-up rebuild with almost no original code is a more serious proposition, even if it also raises the bar for scrutiny.
That does not mean every remake needs to discard its old codebase. Preservation, compatibility, and performance can sometimes argue for restraint. But Ubisoft’s chosen route makes sense if the goal is to bring Black Flag into the same broad technical era as newer Assassin’s Creed work rather than merely polish the old executable.
The risk is that such ambition can alienate players whose expectations are anchored to the original. Someone who remembers running the 2013 game on modest hardware may not intuitively understand why Resynced demands careful settings choices. Ubisoft’s communication challenge will be to make clear that this is not the old PC version with nicer water; it is a modern PC game built around modern rendering assumptions.

The Windows Angle Is Stability Before Spectacle​

For Windows users, the most useful part of Overclock3D’s early report is not a promise of maximum settings glory. It is the stability claim. A game that runs without major stutters is easier to recommend, easier to troubleshoot, and easier to tune than one that lurches unpredictably regardless of hardware.
That has practical consequences for enthusiasts and IT-adjacent users who maintain shared gaming PCs, living-room systems, test benches, or review rigs. If shader precompilation is quick and happens at first boot, the game is less likely to create confusing reports of “random” hitching after every new area. If the experience is almost stutter-free during gameplay, performance tuning can focus on normal variables such as resolution, preset choice, VRAM headroom, and upscaler behavior.
This does not eliminate the usual Windows gaming checklist. Driver versions still matter. Background overlays can still interfere. Storage speed, thermal behavior, and memory pressure can still affect the experience. But when a game’s own shader pipeline is not the obvious culprit, troubleshooting becomes less of a guessing game.
The explicit driver baseline — AMD Software 26.6.4 and Nvidia’s GeForce 610.74 driver for Windows 10/11 — is also useful for anyone comparing early results. If a player sees radically different behavior on another driver branch, that difference becomes part of the diagnostic trail. If launch-day drivers supersede those versions, the public performance conversation may shift again.

Action checklist for admins​

  • Treat Resynced as a modern Anvil Engine title, not as a lightweight 2013-era PC game.
  • Start testing with current AMD or Nvidia drivers appropriate to the Windows 10/11 system in use.
  • Let the first-boot shader precompilation step complete before judging gameplay smoothness.
  • Tune graphical settings before assuming the game is defective; the review’s smoothness claim is tied to using the right settings.
  • Watch VRAM behavior when moving between presets, since Overclock3D identified VRAM usage as a core testing area.
  • If benchmarking, separate shader-precompilation time, traversal smoothness, and average frame rate rather than collapsing them into one score.
The checklist is deliberately conservative because the available source material does not provide exact preset recommendations or VRAM thresholds. That restraint is important. The right lesson from the early review is not “set everything to ultra.” It is that the game appears technically disciplined enough to reward sane configuration.

Early Access Means Promising, Not Proven Forever​

The phrase “early access” in the source material should keep everyone honest. Ubisoft gave Overclock3D early access for testing, and the outlet’s findings describe that testing window. They are valuable, but they are not the same thing as a long-tail public launch across thousands of hardware combinations.
PC launches often change shape after the first wave of users arrives. Edge cases appear. Laptop GPUs complicate the picture. Older Windows installations expose driver leftovers and background conflicts. Players discover settings combinations no reviewer had time to exhaust.
That does not invalidate Overclock3D’s findings. In fact, early access performance testing is most useful when it identifies whether the fundamentals are sound. Stutter behavior is one of those fundamentals, and the report’s answer is clearly positive. The game runs without major stutters, shader precompilation completes quickly, and the expected gameplay experience is almost stutter-free when settings are appropriate.
The unresolved questions are narrower but still important. How does Resynced behave on low-VRAM GPUs? Which upscalers are supported, and how do they compare visually? Where do CPU limits appear? Which graphical settings deliver the best quality-to-performance tradeoff? The source material says those areas are tested in depth in the review, but the excerpt provided here does not include the actual data.
That absence should not be filled with speculation. A responsible performance article separates what has been reported from what remains to be measured. The reported result is a strong first impression on stutter and baseline smoothness. The remaining work is the hardware-by-hardware map that tells each player how close they can get to the remake’s visual ceiling.

Ubisoft’s Best PC Optimization Is Invisible​

The funny thing about good PC performance work is that players rarely notice it directly. They notice the absence of irritation. They notice that the game does not freeze when a new effect appears, that camera movement stays fluid, that the first boot asks for a brief wait rather than turning the first hour into a compilation lottery.
That is why Overclock3D’s report, while based on a limited excerpt here, is more meaningful than a typical pre-release compliment about graphics. Improved visuals are expected in a remake. Refined combat and story are part of the sales pitch. An almost stutter-free PC experience is the part that suggests engineering discipline.
The shader precompilation detail is especially encouraging because it shows a willingness to spend time before gameplay to protect time during gameplay. Players may grumble about precompilation screens, but most would rather wait briefly at startup than hit invisible potholes during exploration. The best implementation is quick enough to feel like routine initialization and thorough enough to prevent shader work from spilling into play.
The source material says Resynced’s shader precompilation completes quickly when the game first boots. That is close to the ideal compromise. It acknowledges the technical reality of modern rendering pipelines without making the user feel punished for owning a PC.
There is a larger industry lesson here. Stutter is not inevitable. It is a product of choices, priorities, and testing coverage. When developers design for the PC’s variability instead of treating it as an afterthought, the platform’s complexity becomes manageable rather than catastrophic.

The Remake Debate Should Move From Nostalgia to Execution​

Every major remake invites the same argument: did this need to exist? For Assassin’s Creed Black Flag Resynced, the technical answer is sharper than the cultural one. If Ubisoft truly rebuilt the game with almost no original code, moved it onto the latest Anvil Engine foundation, refined combat and story, improved graphics, and added new content, then this is a substantial production rather than a packaging exercise.
Whether that satisfies every fan is a different matter. Some players value the feel and historical texture of the original precisely because it belongs to 2013. Others want the setting and premise rebuilt with modern fidelity and smoother systems. A remake cannot fully serve both instincts at once.
PC performance is where that debate becomes concrete. If the remake runs poorly, nostalgia wins by default because the old game becomes the better practical experience. If the remake runs smoothly, then Ubisoft earns the right to argue that the rebuild offers more than sentiment.
Overclock3D’s early report gives Resynced that opening. The outlet’s assessment is not that the game merely looks better, but that Ubisoft has done a great job avoiding the stutter patterns associated with many modern PC releases. That is the kind of execution that can justify revisiting a classic.
Still, the remake’s success will depend on more than first impressions. The public PC audience will judge it across driver updates, hardware tiers, monitor resolutions, and personal tolerance for image reconstruction. The more ambitious the rebuild, the more important scalability becomes.

The Concrete Read for Windows Players​

The clearest message from the early performance material is that Assassin’s Creed Black Flag Resynced should be approached as a modern PC release with encouraging stutter behavior, not as an old game that happens to have been visually refreshed. Overclock3D’s testing points to a remake that has been rebuilt deeply, uses current Ubisoft engine technology, and benefits from a fast first-boot shader precompilation step.
For players, that shifts the buying and tuning calculus. The main fear is not, based on this report, that the game is doomed by unavoidable shader hitching. The more realistic concern is whether a given GPU and settings mix can maintain the smoothness the review describes.
  • Ubisoft’s remake is described as from-the-ground-up, with almost no original code carried forward.
  • Resynced uses the latest incarnation of Ubisoft’s Anvil Engine and shares technological underpinnings with Assassin’s Creed Shadows.
  • Overclock3D reports that the game runs without major stutters and offers an almost stutter-free gameplay experience.
  • Shader precompilation reportedly completes quickly on first boot, which is a strong sign for day-to-day PC smoothness.
  • The review’s smoothness claim is conditional on using appropriate graphical settings.
  • Early testing used AMD Software 26.6.4 and Nvidia’s GeForce 610.74 driver for Windows 10/11.
The cautious optimism is warranted. Resynced appears to be doing the one thing a modern PC remake absolutely must do: keep the player’s motion through the world intact. If Ubisoft can preserve that behavior through launch updates, wider driver coverage, and the chaos of real-world Windows machines, Assassin’s Creed Black Flag Resynced may become the rare nostalgia project whose most important upgrade is not what players see in screenshots, but what they stop feeling in frame-time spikes.

Ubisoft has just released Assassin’s Creed Black Flag Resynced on PC with Anvil Engine rendering, Ray Tracing, and DLSS 4.5 Multi-Frame Gen, and DSOGaming’s first 4K benchmark shows a remake that is fast without Ray Tracing but much less settled once RT is enabled. The headline is not that an NVIDIA GeForce RTX 5090 can brute-force a modern Ubisoft game at 4K; it is that even the fastest consumer-class GPU in the test still runs into stutter, utilization, and frame-pacing behavior that raw averages hide. Black Flag Resynced looks like a better-behaved PC release than Assassin’s Creed: Shadows in this first pass, but it also reinforces the new rule of premium PC gaming: upscaling is no longer a rescue tool, it is part of the design budget.

Assassin’s Creed Black Flag Resynced arrives with exactly the kind of PC feature list that now separates a modern remake from a higher-resolution reissue. Ubisoft is using the Anvil Engine, and the PC version supports Ray Tracing, DLSS 4.5, and Multi-Frame Gen. Official Ubisoft material has framed Resynced as a modernized rebuilding of Black Flag rather than a simple touch-up, and that matters because the game is now being judged less like a nostalgia product and more like a contemporary PC showcase.
DSOGaming’s early technical testing is useful because it gets past the trailer language quickly. The site tested the game on an AMD Ryzen 9 7950X3D, 32GB of DDR5 at 6000Mhz, an NVIDIA GeForce RTX 5090, Windows 10 64-bit, and the GeForce 610.74 driver. That is not a midrange configuration struggling under ambition; it is a top-end test bed asking whether Ubisoft’s renderer, driver path, and frame-generation stack behave properly when hardware limits should be unusually distant.
The answer is mixed. At Native 4K on Ultra High without Ray Tracing, DSOGaming reports a minimum of 66FPS and an average of 78FPS. That is a strong baseline for a modern 4K release and suggests that Resynced, at least in rasterized rendering, is not the kind of port that immediately forces even high-end users into compromise.
The complication is that this baseline is not the experience Ubisoft is implicitly selling when it advertises Ray Tracing and DLSS 4.5 with Multi-Frame Gen. Those features are not decorative anymore. They are the difference between “this runs well” and “this feels like a 2026 PC release,” especially for players on high-refresh 4K displays.

Native 4K Is Strong, but the Presets Do Less Than PC Players Expect​

The most reassuring number in DSOGaming’s benchmark is the Native 4K Ultra High result without Ray Tracing: 66FPS minimum, 78FPS average. On the tested RTX 5090 system, that means Black Flag Resynced can clear the traditional 60FPS bar at 4K without relying on DLSS or frame generation, provided Ray Tracing stays off. For players who prioritize clean native presentation over every lighting feature, that is the best news in the first report.
But the preset scaling is less impressive. DSOGaming says switching from Ultra High to Very High gave only a small performance boost, while High and Medium delivered much bigger gains. Low reportedly performed almost the same as Medium, and the Very Low and Ultra Low presets finally produced significant performance improvements.
That pattern matters because PC players often use presets as a quick diagnostic ladder. If a game is not smooth, the expected move is to step down one or two levels and recover a meaningful amount of headroom. In Black Flag Resynced, the early evidence suggests the top end of the preset stack is compressed: Very High may not buy much, and the more meaningful gains arrive only when the player moves far enough down the ladder to make more visible compromises likely.
This is where the comparison to Assassin’s Creed: Shadows becomes important. DSOGaming’s view is that Black Flag Resynced runs noticeably better than Shadows, but also that it follows a similar pattern: graphics presets do not provide huge performance improvements at the high end. In other words, Ubisoft may have improved the floor but not fully solved the tuning problem.
For Windows users, the practical takeaway is simple: do not assume the preset menu is the primary performance lever. On high-end NVIDIA hardware, the early benchmark says the more decisive switch is not Ultra High versus Very High; it is Ray Tracing versus no Ray Tracing, and native rendering versus DLSS.

Ray Tracing Is the Feature That Turns a Smooth Run into a Diagnosis​

Black Flag Resynced includes two Ray Tracing modes, Standard and Extended, and also allows PC players to push Ray Tracing and BVH Quality to Ultra High manually. Extended mode uses Ray Tracing and BVH Quality at Very High, while the manual maximum goes beyond that. On paper, this is exactly what PC players ask for: named modes for sane defaults, plus deeper controls for people who want to push expensive settings.
In DSOGaming’s test, Standard Ray Tracing drops the minimum framerate just below 60FPS. Extended Ray Tracing lowers it further. The surprising part is that Max RT and Extended RT reportedly showed no performance differences at all.
Ray Tracing configurationRay Tracing settingBVH Quality settingReported performance behaviorPractical read
Standard RTStandard modeStandard modeMinimum drops just below 60FPSFirst RT step already crosses the 60FPS line
Extended RTVery HighVery HighMinimum falls furtherHigher RT mode costs more headroom
Manual Max RTUltra HighUltra HighNo performance difference versus Extended RTTop manual settings may not scale as expected
That last point can be read two ways, and neither is fully satisfying. The charitable interpretation is that the relevant scene in the built-in benchmark does not meaningfully stress the difference between Extended and Max RT. The less charitable interpretation is that the setting is not translating into a measurable workload increase, either because of an engine cap, a driver path, or a scene-dependent bottleneck elsewhere.
The benchmark does include a built-in tool, and DSOGaming describes it as representative of in-game performance. That is important because built-in benchmarks can sometimes be misleading marketing loops, but in this case the site treats the sequence as useful and repeatable. The repeated nature of the Ray Tracing behavior therefore deserves attention.
The more serious issue is not just the framerate drop. DSOGaming reports two consistent stutters at the end of the benchmark scene when Ray Tracing is enabled, and says those stutters are absent without Ray Tracing. That is the kind of finding that average FPS can bury and players can feel immediately.
A minimum just below 60FPS is survivable. A repeatable frametime spike is harder to ignore. It breaks motion, it undermines the point of paying for a premium display, and it can make a game feel worse than its average suggests.

The RTX 5090 Utilization Drop Is the Real Warning Sign​

The oddest data point in DSOGaming’s report is not the Ray Tracing cost; RT is supposed to cost performance. The oddity is that GPU utilization on NVIDIA GPUs reportedly drops to 90% at numerous times, including a cited example where the NVIDIA RTX 5090 is running at 90% “for no apparent reason.” On a system built around a Ryzen 9 7950X3D, 32GB of DDR5 at 6000Mhz, and an RTX 5090, that is exactly the kind of underutilization that suggests software rather than silicon is holding the line.
DSOGaming notes that this could indicate a CPU or RAM bottleneck, but also says none of the CPU cores were maxed out. That distinction is important. A CPU bottleneck does not always present as one obvious core pinned at 100%, especially in engines with complex scheduling behavior, but the absence of maxed cores weakens the simplest explanation.
The more useful reading is that Black Flag Resynced may have a pipeline problem under certain conditions on NVIDIA hardware. That could involve driver overhead, render-thread behavior, memory management, shader compilation, BVH updates, or scene traversal work that fails to keep the GPU fed. The benchmark does not prove which layer is responsible, and DSOGaming properly avoids certainty, but the symptom is familiar to anyone who has profiled high-end PC games: the GPU is expensive, available, and waiting.
This is where the Windows angle becomes more than operating-system trivia. The test was conducted on Windows 10 64-bit with the GeForce 610.74 driver. That combination matters because performance behavior in a modern DX-era title is not just “the game”; it is the game, the OS graphics stack, the display path, the driver branch, the shader cache, and sometimes the overlay ecosystem. One benchmark cannot isolate all of those variables.
Still, if an RTX 5090 drops to 90% utilization repeatedly in a built-in benchmark while CPU cores are not visibly saturated, Windows players should treat early performance claims with caution. The game may be fast, but it may not yet be clean. That difference matters more at the high end than anywhere else, because high-end users notice the missing 10%.

DLSS 4.5 Fixes the Framerate Problem, Not Every Presentation Problem​

DLSS 4.5 with Multi-Frame Gen is the escape hatch in DSOGaming’s test, and a powerful one. At 4K on Ultra High with Max Ray Tracing and DLSS 4.5 Quality Mode, the benchmark stayed over 70FPS at all times. With MFG X2, it stayed above 120FPS at all times. The article also references MFG 3X-6X modes, which reportedly made the experience even smoother.
That is a dramatic result, but it needs careful interpretation. DLSS Quality Mode is doing the foundational work by reducing the cost of the rendered frame while trying to preserve a 4K-class image. Multi-Frame Gen then increases displayed framerate by inserting generated frames between traditionally rendered ones. The result can be transformative on a high-refresh monitor, but it is not the same as the engine natively rendering every frame at that rate.
This distinction is not pedantry. DSOGaming calls the DLSS 4.5 Multi-Frame Generation implementation “decent” but “not among the best,” and reports visible artifacts during very fast camera movements. The site also says most players will not notice those artifacts in normal gameplay. That is a fair middle ground: the technology is good enough to recommend in many situations, but not so invisible that it should be treated as free performance.
The recommendation from DSOGaming is also properly conditional. The site suggests using DLSS 4.5 MFG to hit higher framerates, provided the base framerate is above 50FPS. That caveat is critical because frame generation works best when the underlying game is already responsive and stable. If the base frame stream is uneven, frame generation can make the counter look better while the control feel remains compromised.
For Black Flag Resynced, DLSS 4.5 appears less like an optional enhancement and more like the intended route to premium RT. Without Ray Tracing, the RTX 5090 can run the game at Native 4K. With Ray Tracing, DSOGaming’s conclusion is that players will need an upscaler.
That should shape expectations for everyone below the RTX 5090 tier. If the top tested NVIDIA card benefits from DLSS Quality and Multi-Frame Gen when Max Ray Tracing is enabled, then more modest GPUs should not treat native 4K RT as a realistic target. The sensible PC tuning path is to establish a stable non-generated base framerate first, then add frame generation once the game is already smooth enough to support it.

Built-In Benchmarks Are Useful, but Stutter Is the Metric That Matters​

The presence of a built-in benchmark tool is a welcome PC feature. It gives reviewers, players, and IT teams a repeatable loop, and it reduces the noise that comes from trying to compare two manual runs through an open-world game. DSOGaming used that tool precisely because it can provide a better benchmark loop sequence.
But built-in benchmarks are not magic. They can tell you whether a change improves a repeatable scene, not whether the entire open world behaves identically. They can reveal repeatable stutter, as this one apparently did, but they cannot guarantee that traversal, streaming, combat, weather, or dense settlements will behave the same way.
That is why the two Ray Tracing stutters at the end of the benchmark are so important. A benchmark that only reported average FPS would have made the RT result sound like a routine tradeoff: enable RT, lose some performance, use DLSS if needed. The frametime graph changes the story. It says there may be a repeatable hitch in the RT path.
For players, the best test is not whether the average looks good after one run. It is whether the frametime graph stays consistent over repeated runs with the shader cache warmed and the same settings applied. If the stutter repeats in the same location only with RT enabled, that is a strong sign that the issue is tied to the RT workload or the engine state it triggers.
For WindowsForum readers, this is also a reminder not to over-index on screenshots of counters. An on-screen 120FPS number with MFG X2 can coexist with traversal hitches, input variance, or camera-motion artifacts. The counter is an entry point, not a verdict.

Ubisoft Has a Better PC Baseline Than Shadows, but Not a Cleaner One​

DSOGaming’s broader comparison to Assassin’s Creed: Shadows is revealing. Black Flag Resynced reportedly runs noticeably better, which is the kind of improvement Ubisoft needed. Shadows has been the natural comparison point because it represents the recent Anvil-powered Assassin’s Creed technical target, and Resynced appears to be less punishing.
But DSOGaming also says Shadows looked better, with more advanced lighting and richer environments, including forests that stood out visually. That is the tradeoff hiding inside the benchmark. Black Flag Resynced can run better, but part of that advantage may come from a presentation that is not quite as ambitious.
That does not make the remake visually weak. It makes it more strategically conservative. Ubisoft is reviving a beloved pirate game and modernizing it for current PC expectations, but the benchmark suggests the company has not fully escaped the engine-level tensions that defined its more demanding releases: expensive lighting, uneven scaling, and reliance on upscaling to turn a premium feature set into a premium experience.
The result is a PC version that seems easier to recommend than a disaster launch, but harder to call polished. It can run well. It supports modern rendering features. It includes a built-in benchmark. It can achieve very high displayed framerates with DLSS 4.5 Multi-Frame Gen. And yet the first technical report still finds RT stutter and unexplained NVIDIA GPU utilization drops.
That combination is increasingly common. The modern PC port does not fail by refusing to launch; it fails by making every user become a graphics engineer for an evening. Black Flag Resynced looks better than that worst case, but not immune to it.

What Windows Gamers Should Actually Change First​

The first mistake many players will make is chasing presets. DSOGaming’s results suggest that moving from Ultra High to Very High is not the lever that transforms performance. High and Medium matter more, Very Low and Ultra Low matter a lot, and Low being close to Medium implies that some parts of the preset stack may not be efficiently spaced.
The second mistake is enabling every RT option and then trying to fix the result with frame generation alone. If Standard Ray Tracing already pulls the minimum just below 60FPS on the tested system, and Extended lowers it further, then the correct order is: choose the RT mode, verify base smoothness, enable DLSS Quality if needed, then consider MFG. Frame generation should be the last multiplier, not the first bandage.
The third mistake is trusting a single run. Since DSOGaming observed consistent stutters at the end of the benchmark with Ray Tracing enabled, users should run the benchmark more than once after changing RT settings. If stutters repeat, the problem is not a random background process; it is probably tied to the rendering path, shader state, or scene behavior.
The fourth mistake is assuming a high-end GPU guarantees full utilization. The reported RTX 5090 dips to 90% utilization are a reminder that the fastest hardware can still be underfed. If utilization is dropping while framerate is under target, lowering GPU-heavy settings may not fix the underlying issue. In that case, DLSS may help by shifting the workload profile, but it may not address every frametime hitch.

Action checklist for admins​

  • Validate the game with the built-in benchmark before approving a shared lab, demo, or high-end gaming-room image.
  • Test with Ray Tracing off, Standard Ray Tracing, and Extended Ray Tracing before touching lower presets.
  • Use DLSS 4.5 Quality Mode as the first upscaling baseline for 4K Ray Tracing tests.
  • Enable Multi-Frame Gen only after the non-generated base framerate is stable and preferably above 50FPS.
  • Watch frametime graphs, not just average FPS, and repeat the benchmark to confirm stutter patterns.
  • Record the Windows version, GPU driver, preset, RT mode, DLSS mode, and MFG multiplier with every result.
For most individual players, the simplest starting profile is Ultra High at Native 4K with Ray Tracing off if image purity is the goal. If Ray Tracing is the priority, DLSS 4.5 Quality Mode becomes the sensible default, with MFG X2 available for high-refresh displays once the base framerate is acceptable. The more aggressive MFG 3X-6X modes may feel smoother, but the visual-artifact report during fast camera movement means they should be treated as preference settings rather than automatic wins.

The RTX 5090 Result Is a Ceiling, Not a Promise​

The benchmark system matters because it defines the ceiling of this first report. A Ryzen 9 7950X3D, 32GB of DDR5 at 6000Mhz, and an NVIDIA GeForce RTX 5090 are not representative of the average Windows gaming PC. If that system needs an upscaler for Ray Tracing at 4K, then most users should assume they will need one too.
This is not a condemnation of DLSS. DLSS 4.5 is one of the reasons modern 4K RT gaming is viable at all, and the numbers here show why NVIDIA has leaned so hard into reconstruction and frame generation. Over 70FPS at all times with DLSS 4.5 Quality Mode and Max Ray Tracing is a strong result. Above 120FPS at all times with MFG X2 is exactly the kind of experience high-refresh PC players are chasing.
But the danger is that frame generation can turn performance discourse into scoreboard watching. A generated 120FPS experience can be excellent, but it depends on the quality of the base frames, the latency path, the artifact profile, and the consistency of frame pacing. DSOGaming’s “decent, but not among the best” assessment is therefore more important than the headline number.
In a slower third-person game, occasional artifacts during very fast camera movement may be acceptable. In normal gameplay, DSOGaming says most players will not notice them. Still, that caveat tells competitive-minded or latency-sensitive players what to test first: camera pans, rapid traversal, foliage-heavy scenes, and any area where the engine streams or updates lighting aggressively.
The better way to think about Black Flag Resynced is as a game with two viable identities. One is a relatively clean Native 4K rasterized remake that clears 60FPS on extreme hardware. The other is an RT-enhanced, DLSS-assisted modern showcase that can display very high framerates but currently carries more caveats.

Why This Launch Matters Beyond One Pirate Game​

Black Flag Resynced is arriving at a moment when PC players are increasingly skeptical of “optimized for PC” claims. The feature stack has become richer, but the path to a stable experience has become more complicated. Ray Tracing, DLSS, Multi-Frame Gen, driver profiles, shader caches, and built-in benchmark loops now form a second game inside the game.
Ubisoft is not alone in this. The industry has moved toward reconstruction-first rendering because native high-resolution, high-refresh, RT-heavy workloads are punishing even on elite hardware. NVIDIA’s DLSS ecosystem exists because brute force is no longer the whole answer. The question is whether developers are using these tools to enhance a stable renderer or to compensate for an unstable one.
DSOGaming’s first benchmark suggests Black Flag Resynced is closer to the former than the latter, but with visible cracks. Without Ray Tracing, it runs well at Native 4K on the RTX 5090. With DLSS 4.5 and MFG, it can deliver high displayed framerates even with Max Ray Tracing. The cracks are the RT stutters, the unexplained NVIDIA utilization drops, and the imperfect Multi-Frame Gen artifact behavior.
That makes the forthcoming broader PC Performance Analysis more important than usual. DSOGaming says its deeper article will benchmark numerous GPUs from both AMD and NVIDIA. That is the piece that should tell us whether the RTX 5090 behavior is an NVIDIA-specific quirk, a high-end CPU scheduling issue, a driver branch issue, or simply how this Anvil workload behaves across vendors.
Until then, the responsible read is cautious optimism. Ubisoft appears to have delivered a remake that runs better than Shadows in this first test, but not one that makes technical scrutiny unnecessary. The best PC releases are no longer judged only by whether they can hit 60FPS; they are judged by whether they can do so consistently, repeatably, and without asking the player to solve the render path manually.

The Settings That Matter Most at Launch​

Black Flag Resynced’s first benchmark gives Windows players enough information to avoid the worst launch-day tuning traps. The game is not an obvious performance catastrophe, but it is also not a set-and-forget showcase for every high-end feature. The settings that matter are the ones that change the rendering path, not the ones that merely shuffle the preset label.
  • Native 4K Ultra High without Ray Tracing is viable on the tested RTX 5090 system, with 66FPS minimum and 78FPS average.
  • Standard Ray Tracing drops the minimum just below 60FPS, while Extended Ray Tracing lowers it further.
  • Max RT and Extended RT showed no performance difference in DSOGaming’s run, so manual Ultra High RT/BVH settings may not be worth chasing immediately.
  • Ray Tracing introduced two repeatable stutters at the end of the benchmark scene; disabling Ray Tracing removed them.
  • DLSS 4.5 Quality Mode pushed Max Ray Tracing above 70FPS at all times, and MFG X2 pushed displayed framerate above 120FPS at all times.
  • Multi-Frame Gen is useful but imperfect here, with reported artifacts during very fast camera movement.
The sane launch profile is therefore not “everything maxed because the GPU is expensive.” It is a staged approach: establish the native baseline, decide whether Ray Tracing is worth the stutter risk, add DLSS Quality if RT is enabled, and only then use Multi-Frame Gen to chase high-refresh smoothness. That order will save more time than bouncing between presets.
Black Flag Resynced looks like a capable PC release with a familiar modern flaw: its best experience depends on technologies that can multiply frames faster than the engine can always deliver them cleanly. If Ubisoft and NVIDIA can address the utilization drops and Ray Tracing stutters, this could become one of the stronger Anvil showpieces on Windows; if not, it will stand as another reminder that in 2026, PC performance is no longer measured by averages alone.
