CachyOS Beats Windows 11 in AAA Gaming Benchmarks: Proton, Mesa, 1% Lows

CachyOS’s latest gaming showing is another reminder that Windows 11 no longer enjoys an automatic performance crown in every PC game. In a recent benchmark set highlighted by XDA, the performance-focused Linux distro edged ahead in two major titles, Cyberpunk 2077 and Warhammer 40,000: Space Marine 2, while Windows 11 still held its ground or won outright in other cases. The broader message is not that Linux has “won” gaming once and for all, but that the gap has narrowed enough that per-game, per-setup evaluation now matters more than platform loyalty.

Background​

Linux gaming has traveled a long road from the era when “gaming on Linux” mostly meant a narrow catalog of native ports and hobbyist experiments. Valve’s Proton compatibility layer changed that trajectory by letting many Windows games run on Linux through Steam, turning a once-fringe proposition into something mainstream enough for handheld PCs and desktop gaming rigs alike. Valve’s own Proton project describes itself as a compatibility tool for Steam Play that allows Windows-exclusive games to run on Linux, while community tracking through ProtonDB has become the de facto reference point for how well specific titles behave in the real world.
That shift matters because gaming performance is no longer just about raw frame rates. It is also about frame-time consistency, shader handling, CPU scheduling, translation overhead, anti-cheat behavior, and whether a game is using DirectX 11, DirectX 12, Vulkan, or some mix of APIs and launchers. As Proton matured, the old assumption that Linux was automatically slower began to erode, especially on modern hardware where driver quality and compatibility-layer optimizations can offset much of the overhead. Valve’s ecosystem, plus community tools like ProtonDB, made it easier to treat Linux as a serious gaming platform rather than a curiosity.
CachyOS sits at the more aggressive end of that evolution. It is not just “Linux, but for games”; it is a performance-tuned Arch-based distribution that emphasizes scheduler tweaks, system-level optimization, and a gaming stack designed to reduce friction. CachyOS’s own gaming documentation says its proton-cachyos build includes quality-of-life changes, selected patches, and compilation optimizations, while its game-performance wrapper temporarily raises the power profile and CPU governor into a gaming-friendly state. That makes it a natural target for benchmark comparisons against Windows 11, because the distro is explicitly trying to squeeze more out of the same hardware.
The XDA-reported benchmark, based on NJ Tech’s YouTube testing, fits neatly into this larger story. On an AMD Ryzen 5 5600X and Radeon RX 6700 XT, CachyOS reportedly beat Windows 11 by roughly 3–10% in several games, with especially strong results in Cyberpunk 2077 and Space Marine 2. At the same time, Windows still took or matched the lead in some titles, which is an important reminder that Linux gaming progress is real but not universal. The most interesting result is not a single victory lap; it is the fact that the platform now looks competitive enough for the lead to swing back and forth depending on the game.

What the New Benchmark Shows​

The headline result is straightforward: CachyOS delivered higher average frame rates and better 1% lows in two high-profile games, which is often the more meaningful metric for a gamer than a simple peak number. In Space Marine 2, CachyOS reportedly reached 81 FPS on average versus Windows 11’s 68 FPS, while also delivering a much stronger 1% low of 72 FPS versus 58 FPS. In Cyberpunk 2077, the gap was narrower but still clearly in CachyOS’s favor, with 98 FPS average and 76 FPS 1% lows compared with Windows 11’s 91 FPS average and 63 FPS 1% lows. Those are not trivial differences; they suggest smoother play, better pacing, and fewer spikes in perceived stutter.

Why 1% Lows Matter​

Average FPS can flatter a system that stumbles under load. A game that averages 90 FPS but dips sharply during combat or traversal can feel worse than one that holds a steadier 80 FPS, because the player experiences uneven delivery rather than a clean, stable stream of frames. That is why the stronger 1% lows in CachyOS are so noteworthy: they imply not just higher throughput, but better consistency. In practice, consistency is often what separates a benchmark victory from a genuinely better play experience.
The benchmark also matters because it was not cherry-picked from a niche indie title or a lightweight esports game. Cyberpunk 2077 and Space Marine 2 are demanding, modern, GPU-heavy games where driver quality, shader behavior, and translation layers all have room to influence the result. If a Linux distro can compete here, it can credibly challenge the assumption that Windows is the default choice for serious gaming. That does not mean every Linux install will do the same, but it does mean the ceiling is now high enough to matter.

Where Windows Still Won​

The story is more balanced when you look at the games where Windows stayed ahead. In The Division 2, the two operating systems reportedly tied in average FPS, while Windows held a modest edge in 1% lows. In The First Descendant, Windows posted a clearer win, with 63 FPS average and a 39 FPS 1% low compared with CachyOS’s 54 FPS average and 38 FPS 1% low. That kind of split result is exactly what you would expect from a mature but uneven compatibility stack: some engines and configurations benefit from Linux’s leaner behavior, while others still favor Windows-specific paths.

• CachyOS’s wins were strongest where frame pacing looked cleaner.
• Windows remained competitive in titles sensitive to compatibility quirks.
• The benchmark supports the idea that game-by-game testing still matters.
• No platform owned the result across the entire suite.

The larger lesson is that Linux gaming is no longer a single-performance story. It is a compatibility story, a driver story, and a tuning story. The platform can outperform Windows in one demanding title and lose in another, sometimes on the same hardware, which makes broad claims far less useful than targeted analysis.

Why CachyOS Can Compete​

CachyOS is built for exactly this kind of comparison. Its gaming stack is not merely a normal desktop Linux setup with Steam installed; it includes the proton-cachyos build, custom wrappers, and a system profile tuned for performance-sensitive use. According to CachyOS’s own documentation, the distro ships a wrapper called game-performance that changes the power profile to performance mode and can also switch an active scheduler into a gaming profile if available. Those details sound small, but on a modern gaming PC, small improvements in latency and scheduling can add up.

The Tuning Advantage​

The important point is that CachyOS is not trying to be a generic operating system. It is trying to be an opinionated platform for users who value performance and are willing to accept some trade-offs in exchange. That creates a meaningful advantage in benchmark comparisons, because Windows 11 is optimized for broad consumer and enterprise use rather than gaming specialization. Windows often carries background services, telemetry components, and general-purpose defaults that are not necessarily designed to minimize gaming latency.
That does not mean Windows is “bloated” in every real-world setup, because many gaming systems are lean and well maintained. But it does mean a distro like CachyOS can sometimes find room to win on the margins. If the benchmark system was already tuned and the Linux side was additionally configured through CachyOS gaming options, then the advantage can come from a stack of modest gains rather than one magic switch.

Proton Is No Longer the Weak Link It Once Was​

A few years ago, the biggest objection to Linux gaming was simple: compatibility. Now that objection is less absolute because Proton has matured, VKD3D-Proton keeps improving DirectX 12 translation, and community reporting shows that a very large share of Windows games now at least launch on Linux. Recent coverage drawing on ProtonDB data suggests nearly 90% of Windows games now manage to run on Linux in some form, even if some still struggle with anti-cheat or edge-case bugs.

Key enablers behind Linux gaming progress​

• Valve’s Proton reduced the barrier to entry for Windows games on Linux.
• ProtonDB gave players a compatibility reality check, not just marketing claims.
• VKD3D-Proton improved the DirectX 12 side of the experience.
• Gaming-focused distros like CachyOS added system-level performance tuning.
• Community testing exposed which games benefit and which still need work.

That ecosystem is why the current benchmark feels credible rather than surprising. Linux did not suddenly become fast; rather, the surrounding software stack became good enough that performance-focused distributions can now expose cases where Linux is, under the right conditions, faster than Windows.

Cyberpunk 2077 as the Showcase Title​

Cyberpunk 2077 is an excellent benchmark for this discussion because it stresses so many parts of the platform at once. It can punish CPU overhead, expose driver inefficiencies, and magnify frame-time irregularities, especially at higher settings and in large open-world scenes. A Linux win in this title is therefore more meaningful than a win in a light or old game, because the engine has enough complexity to reveal real differences in the rendering path. That makes the CachyOS result especially interesting.

Why the Margin Matters​

The reported gap in Cyberpunk 2077 was not enormous in average FPS, but the 1% low difference was more compelling. A 98 FPS average versus 91 FPS is nice; 76 FPS 1% lows versus 63 FPS is what players actually feel when a scene becomes busy. That suggests CachyOS may be handling background load or frame scheduling in a way that produces a smoother experience under pressure. In a game where visual smoothness is part of the appeal, that kind of consistency can matter more than a flashy benchmark headline.
It is also worth noting that Cyberpunk 2077 has become something of a proving ground for gaming stacks. If a platform can run it well, especially on AMD hardware, it signals maturity in the graphics stack and compatibility layer. That is one reason Linux gaming enthusiasts keep returning to it in benchmarks and comparison videos.

Practical interpretation​

The likely explanation is not “Linux is universally better,” but rather that this particular combination of Ryzen 5 5600X, Radeon RX 6700 XT, and CachyOS tuning hit a sweet spot. AMD’s open graphics ecosystem has generally played well with Linux, and that can reduce the friction that sometimes appears on other configurations. On top of that, CachyOS’s performance-focused defaults may have helped minimize latency, make better use of CPU cores, or simply keep the game in a steadier state over the test sequence.

• Strong 1% lows indicate better consistency.
• AMD hardware often pairs well with Linux graphics stacks.
• Game-specific behavior can dwarf abstract OS preferences.
• The result is impressive, but still configuration-dependent.

In other words, Cyberpunk 2077 did not prove that Linux always wins. It proved that the Linux stack can now be competitive enough to outpace Windows in a modern blockbuster title when the pieces line up correctly.

Space Marine 2 and the Frame-Time Story​

Space Marine 2 may be the more striking data point because the margin appears larger and the 1% lows stronger. Hitting 81 FPS average on CachyOS against 68 FPS on Windows 11 is a meaningful leap, and the 1% low spread suggests fewer interruptions and less judder during action-heavy gameplay. If the test is representative, then CachyOS is not merely equal to Windows here; it is delivering a visibly better pacing profile.

Why this game is revealing​

Modern shooters and action games are unforgiving because they expose microstutter immediately. A game like Space Marine 2 is full of fast movement, particle effects, and heavy combat sequences, which means even a small instability in the frame delivery pipeline can feel worse than the benchmark chart suggests. That is why the Linux result stands out: it is not just a synthetic gain, but a sign that the distro may be handling workload spikes more gracefully.
This matters because game performance is increasingly judged by feel, not just by averages. If CachyOS can deliver higher and more stable output in a title like this, it strengthens the case that Linux gaming is now good enough for a meaningful subset of players. The caveat, of course, is that other users have reported different outcomes depending on patches, Proton versions, and driver revisions. That variability is the story.

The patch-and-driver problem​

Space Marine 2 is also a reminder that gaming performance is fragile. Community reports often point to updates, patches, or driver changes that can swing results in either direction, particularly when translation layers are involved. That means today’s benchmark winner can become tomorrow’s frustrating outlier after a game patch or a graphics driver update. For Linux users, especially those tracking bleeding-edge distros, the upside of performance can come with a maintenance burden.

• Large performance wins can be real but unstable over time.
• Game patches can alter Linux results more than many users expect.
• Driver and Proton updates can change frame pacing suddenly.
• Benchmarks are snapshots, not permanent verdicts.

That volatility should not diminish the result, but it should keep expectations grounded. Space Marine 2 shows what Linux can do at its best; it also hints at how easily that best can shift if the surrounding software changes.

Where Windows Still Has the Edge​

Windows 11 is not fading into irrelevance. In the same benchmark set, it still matched or beat CachyOS in some titles, and that matters because gaming is a portfolio activity, not a one-game contest. Many players do not buy an operating system to optimize around a single favorite title; they buy it to run a library of games with the least hassle. In that broader sense, Windows retains a major advantage simply because it remains the baseline target for most developers.

Compatibility still matters​

Even when Linux performance is excellent, there is still the question of how easy a game is to run, update, and maintain. Anti-cheat systems, launcher behavior, modding tools, and video playback can all become sources of friction. ProtonDB and community reports remain essential because a game that benchmarks well in one session can still fail to launch cleanly in another. That means the best possible Linux result and the most common Linux experience are not always the same thing.
Windows also keeps the edge in situations where developers test primarily against Microsoft’s platform. Shader compilation paths, driver behavior, and API assumptions are often tuned first for Windows, and Linux compatibility layers have to catch up. That is why a title like The First Descendant can still favor Windows even when other games tilt the other way.

A split market, not a replacement​

The sensible conclusion is that gaming is becoming more pluralistic rather than strictly “Linux versus Windows.” If you own a machine and are willing to choose the OS based on the games you play most often, Linux is increasingly viable. If you want the least troubleshooting across the broadest library, Windows still has the simplest default story. Both statements can be true at once, and the CachyOS benchmark reinforces that reality rather than overturning it.

• Windows still dominates the mainstream gaming default.
• Linux now offers real performance upside in select cases.
• The best platform depends on your library and tolerance for tinkering.
• Uniform superiority is no longer a realistic claim for either side.

That nuance is important because it changes the debate from ideology to practicality. A few years ago, Linux users were mostly arguing for “good enough.” Now they can point to cases where Linux is not just good enough, but better.

The Role of AMD Hardware​

The benchmark hardware matters almost as much as the operating systems. An AMD Ryzen 5 5600X and Radeon RX 6700 XT is a very Linux-friendly pairing, especially relative to older or more closed graphics stacks. AMD’s open-source driver ecosystem on Linux has long been a strength, and this kind of result often looks best on hardware where the driver path is mature and well understood. That does not guarantee a Linux win, but it does make one more plausible.

Why this pairing helps​

AMD’s Linux graphics support has generally benefited from active upstream work and broad community testing. That means users often see stronger out-of-the-box behavior with fewer proprietary dependencies than they might encounter on more complicated stacks. When a distro like CachyOS layers performance tweaks on top, the result can be surprisingly competitive. In benchmark terms, the hardware is not just “good”; it is the kind of hardware where Linux gets to show its strongest side.
The CPU also matters because gaming performance is not solely about the GPU. Translation layers, background services, and scheduler decisions all have room to influence frame pacing, particularly in CPU-heavy or mixed workloads. A six-core Zen 3 chip like the 5600X is still perfectly capable for modern gaming, but it also leaves enough headroom for OS-level differences to show up.

How much can you generalize?​

Not very much, and that is the responsible answer. A result on AMD hardware does not automatically translate to NVIDIA systems, laptop hybrids, handheld APUs, or heavily modded Windows games with unusual launchers. It also does not predict how a specific title will behave after a patch. The benchmark is most useful as evidence that the Linux gaming stack can shine when the hardware and software ecosystem are aligned.
A few practical conclusions follow from that:

• AMD plus Linux remains a strong combination for gaming-focused users.
• Benchmarks are system-specific, not universal laws.
• Driver quality can matter as much as raw OS choice.
• Game engine behavior often determines the winner more than marketing does.

For readers thinking about a dual-boot setup, this is the real takeaway: if your hardware aligns with Linux strengths, the performance gap may be smaller than it once was, and in some games it may actually reverse.

What This Means for the Linux Gaming Ecosystem​

The broader significance of CachyOS’s benchmark is not that one distro won two games. It is that the Linux gaming ecosystem now has enough momentum that performance-oriented distributions can start making credible claims against Windows 11 on modern titles. That is a major psychological shift for enthusiasts who remember when Linux gaming was mostly about compatibility workarounds and a very limited native catalog.

Proton has changed the conversation​

With Proton, the question is no longer whether Windows games can run on Linux at all. It is whether they run well enough, whether they stay stable, and whether the Linux stack can sometimes outperform Windows on the same machine. Valve’s Proton project and its broader ecosystem have made that conversation possible, while ProtonDB has helped users separate reality from hope. The current state of play is a lot healthier than it was even a few years ago.
The presence of gaming-focused distros like CachyOS also creates a second layer of competition inside Linux itself. Once users know Linux gaming is viable, they start asking which distribution extracts the most performance or delivers the least friction. That competitive pressure is healthy, because it pushes maintainers to refine kernel choices, scheduler behavior, shader caching defaults, and gaming wrappers.

Consumer and enthusiast impact​

For consumers, the message is empowering but not simple. You can absolutely build a competitive gaming system around Linux now, especially if your library consists of titles that play nicely with Proton. But you should still expect some trial and error, and you should still think in terms of your games, your hardware, and your tolerance for tinkering. For enthusiasts, CachyOS is evidence that Linux performance tuning is not just a theoretical exercise; it can produce measurable gains against a dominant commercial OS.

• Linux gaming is now a legitimate tuning problem, not a novelty.
• Community data tools remain essential for decision-making.
• Performance distros are creating meaningful differentiation.
• Windows can still win, but no longer by default in every case.

This is exactly the kind of market development that changes habits slowly rather than all at once. A few benchmark charts do not trigger mass migration, but they do chip away at the old assumption that Windows always equals better gaming performance.

---

Strengths and Opportunities​

CachyOS’s showing highlights how much room there still is for optimization in the gaming stack. The biggest opportunity is not to “replace Windows” overnight, but to keep proving that Linux can be a first-class gaming environment for users who value performance, control, and transparency.

• Higher 1% lows can deliver a noticeably smoother experience than Windows in the right games.
• AMD hardware support gives Linux a strong foundation for gaming performance.
• Proton maturity means compatibility is now good enough to compete on performance, not just launch success.
• Gaming-focused tuning in CachyOS can extract extra value from the same hardware.
• Choice and flexibility allow enthusiasts to optimize for their own libraries.
• Linux community momentum keeps improving tools, documentation, and troubleshooting.
• Benchmark visibility helps normalize Linux as a serious gaming option.

The opportunity here is not purely technical. It is also cultural. Every benchmark like this reduces the stigma that Linux is only for developers or tinkerers, and that makes it easier for more users to try it without feeling like they are sacrificing their gaming hobby.

Risks and Concerns​

The danger in celebrating results like this is overgeneralization. A benchmark win in two demanding games is encouraging, but it does not erase compatibility issues, driver quirks, anti-cheat problems, or the messy reality that Linux gaming can still be more hands-on than Windows for many people.

• Game-by-game variability can make results hard to predict.
• Updates and patches can flip performance in either direction.
• Anti-cheat systems still block or complicate some popular games.
• Driver or Proton regressions can quickly spoil a good setup.
• User expectations may become unrealistic after headline wins.
• Hardware differences can produce very different outcomes.
• Extra tuning can be a burden for casual players.

There is also a reputational risk for Linux advocates if the narrative becomes too triumphalist. If users install CachyOS expecting universal Windows-beating performance and then hit a few problematic titles, they may conclude the whole premise was overstated. The more honest message is that Linux is now competitive often enough to be worth a serious look.

---

Looking Ahead​

The next phase of Linux gaming will probably be less about proving that it works and more about making it predictable. That means better defaults, fewer per-game surprises, more stable compatibility layers, and clearer guidance for users who want the best performance without constant tinkering. If CachyOS and other performance-oriented distros keep refining their stacks, the line between “Linux as an alternative” and “Linux as a preferred gaming platform” will continue to blur.
The competitive pressure on Windows is also likely to intensify. Microsoft still has the advantage of being the default for most PC gamers, but that default status becomes less secure every time Linux matches or beats it in visible benchmark tests. If more modern titles continue to show Linux wins on the right hardware, the industry may have to treat Linux optimization as a mainstream concern rather than a niche courtesy.

• More benchmarks will help identify which engines favor Linux and why.
• Proton updates may close remaining performance gaps in demanding games.
• GPU driver improvements could further boost AMD and NVIDIA performance on Linux.
• Anti-cheat progress remains a major factor for broader adoption.
• Distro-level tuning may become a bigger differentiator than raw kernel version.
• Handheld gaming PCs could accelerate Linux acceptance even further.

The real story, then, is not that Windows has been dethroned once and for all. It is that dethroning Windows in specific games is now plausible, and that alone is a profound change from the old Linux gaming landscape. CachyOS’s benchmark doesn’t end the debate; it updates it, and the new version of the argument is much more interesting.
