While the headline-grabbing claim is that the unofficial DLSS 5 mod can make CD Projekt Red’s decade-old RPG look even more remastered than the official remaster, a closer read of the experiment reveals a classic PC modding cautionary tale. Between version compatibility roadblocks, severe motion ghosting, and non-player characters that look like they were scrubbed through an uncanny AI filter, the test highlights the vast gulf between slapping an unofficial neural-rendering DLL onto an older game engine and shipping a properly tuned graphics update.
The Version Catch: What Was Actually Tested?
Before evaluating how the visuals held up, PC players need to understand a critical technical limitation in the test setup. CD Projekt Red recently released the Remastered Update for The Witcher 3: Wild Hunt on PC, a free update that DSOGaming notes added Path Tracing support to the title. However, Biswas reported that when he tried to install and run the DLSS Swapper mod with the DLSS 5 library on The Witcher 3: Wild Hunt Remastered, that version of the game never worked with the mod installed despite basic troubleshooting.
Instead, the author conducted all of his DLSS 5 testing on the older "next-gen" version of the game—which can be manually selected in Steam—while keeping the official remastered version installed on a separate drive to compare the two without repeatedly downloading over 60GB of game data. He also noted that the mod functions on the original release of the game.
For Windows gamers, that distinction is essential: this was not a direct toggle of DLSS 5 on top of the newest Path Tracing remaster build, but rather a side-by-side comparison pitting an unofficially modded next-gen branch against the unmodded official remaster. Furthermore, the MakeUseOf report does not specify the test rig's exact GPU model, display resolution, driver version, or specific DLSS binary build, meaning PC enthusiasts should view these observations as a subjective visual experiment rather than a controlled hardware benchmark.
How the Unofficial Mod Alters the RED Engine
According to Biswas’s testing, the leaked DLSS 5 implementation used via the community tool DLSS Swapper (credited in his report to developer Rakanki911) works by injecting the nvngx_dlssnr.dll file into the game's existing DLSS library. Rather than overhauling polygon meshes or replacing high-resolution texture packs, the mod's visible impact is concentrated almost entirely on general lighting and global illumination (GI).
Because The Witcher 3 runs on an older iteration of CD Projekt Red's proprietary technology derived from RED Engine 3—originally built for The Witcher 2—the author found that the shift in external lighting calculations felt much more dramatic here than in his previous tests with Cyberpunk 2077 or Onimusha.
In practice, that aggressive lighting overhaul proved to be a double-edged sword depending on where Geralt happened to be standing:
- Where the Mod Shines: In moody, atmospheric regions such as the windswept Skellige Islands or the crowded streets of Novigrad, Biswas reported that the DLSS 5 mod looked exceptional and, in specific static scenarios, slightly better than the official remaster. He also noted that HDR presentation looked significantly better with the mod enabled than in the vanilla remastered build, whose lighting he found comparatively flat, and remarked that certain scenes recalled the warmer lighting style of the original Xbox 360-era Witcher experience.
- Where the Mod Breaks Down: In vibrant, high-saturation regions like Blood and Wine's Toussaint, the mod left the scenery looking washed out even on an HDR display. Worse yet, once the camera or characters started moving, the unofficial library introduced heavy ghosting—a flaw the author also encountered when experimenting with DLSS 5 on older PlayStation 2 titles.
- The Uncanny NPC Problem: Perhaps the most jarring side effect of uncalibrated neural rendering is what it does to human faces. Biswas observed that NPC models frequently looked unnatural and blatantly AI-generated, joking that players should not have to accept quests from characters that look like they were generated by an AI chatbot.
That polarized reaction aligns with broader community experimentation around The Witcher 3 and DLSS 5. In Reddit's Witcher communities, players testing experimental DLSS 5 setups have offered wildly conflicting verdicts—ranging from praise for how details pop to complaints that character faces look weirdly "oiled up" or barely changed at all.
| Visual & Technical Category | Unofficial DLSS 5 Mod (Next-Gen Branch) | Official Remastered Version (Unmodded) |
|---|---|---|
| Game Build Compatibility | Worked on the Steam "next-gen" and original branches; failed to launch/work on the Remastered build in the author's test. | Native, officially supported PC build with recent Path Tracing support. |
| Global Illumination & HDR | Strong contrast and improved HDR punch in Skellige and Novigrad, but washed-out colors in vibrant Toussaint. | Flatter lighting and weaker HDR by comparison in the author's view, but consistent artistic grading across regions. |
| Motion & Stability | Heavy motion ghosting; requires avoiding ReShade overlays to prevent crashes. | Free of unofficial DLL injection artifacts and third-party hook conflicts. |
| Character Presentation | Can produce uncanny, "AI-filter" facial artifacts on NPCs. | Preserves CD Projekt Red's intended character models and textures. |
Practical Takeaways and Safety Cautions for PC Modders
If you are tempted to tinker with unofficial neural-rendering injectors on your own Windows rig, a healthy dose of veteran IT skepticism is in order. While Biswas noted that the DLSS Swapper workflow makes toggling the effect inside the game relatively simple once extracted, he stressed two important precautions: always back up your save files beforehand, and avoid stacking ReShade mods on top of the setup, as doing so can trigger game crashes.
Beyond game stability, PC users should remember that "leaked" DLL files and third-party swapper utilities operate completely outside official support channels. Dropping unverified binaries into a game directory carries inherent security and stability risks, and claims that a modded DLL will run smoothly on almost any RTX graphics card should not be taken as a guarantee across different Windows driver branches or GPU architectures.
Ultimately, even after praising the mod's HDR handling and localized lighting upgrades in Novigrad and Skellige, Biswas concluded that he still prefers playing the official remaster over the DLSS 5 modded build. Until a studio like CD Projekt Red can officially integrate and manually tune neural rendering parameters to eliminate ghosting and protect character models from looking like plastic wax figures, unofficial DLSS 5 injection remains an intriguing technical preview rather than a true replacement for a proper remaster.
