An unreleased AMD Adrenalin driver reportedly contains the upcoming FSR 4.1 DLL file, which can work on RDNA 3 GPUs with Proton FP8 emulation.
User Obtains FSR 4.1 DLL from "Vangaurd" Adrenalin 26.3.1 Drivers; Works on RDNA 3 GPUs Using Linux
Once again, we see newer upscaling technologies being implemented on older hardware. This time, it's not the FSR 4.0.3, but the leaked FSR 4.1, which is reportedly from a test build called "Vanguard" Adrenalin 26.3.1 driver, available through AMD's invite-only beta channel. Someone on Guru3D forums just obtained the FSR 4.1 DLL file from the upcoming Adrenalin driver and uploaded it for users to experiment.
The file "amdxcffx64-v2.1.0.968(4.1.0)" is available to download from Gurud3D forums, and as per the uploader, "The Creator", the new FSR 4.1 delivers the same performance as the FSR 4.0.3 on Linux with MESA 26.1.0. While the user didn't share any visual comparison between FSR 4.0.3 and FSR 4.1.0, some users have already started experimenting with the new FSR 4 version.
The user/AthleteDependent926 explains the method to install the FSR 4.1.0 by replacing the "amdxcffx64.dll" file in System32 with the leaked FSR 4.1 DLL. He says that one can also turn it on using Optiscaler, but the method he explained works just fine. As you can see, his The Last of US Part II setup window shows FSR 4.1.0 in the Anti-Aliasing Mode, which confirms it works even with the older GPUs such as the Radeon RX 7900 XT.
The two shared screenshot comparisons reveal what one can expect from the latest FSR 4.1.0 vs FSR 4.0.3 on Ultra Performance mode. In the first comparison slide, we can see slight sharpening in Hogwarts Legacy with the FSR 4.1.0, and in the other slide, the difference is quite significant. The FSR 4.1.0 delivers far sharper foliage vs FSR 4.0.3, but if you look at the wall texture, there isn't a huge difference. The tree trunk also shows clearer details, and so does the character's outfit.
But then there is another comparison of Monster Hunter Wilds, where the FSR 4.1.0 doesn't seem to be doing much vs FSR 4.0.3. However, some users said they saw a noticeable difference in visual quality with the newer FSR 4 version.
Still, it will be interesting to see how well other presets will do against FSR 4.0.3, especially the Quality and Balanced modes, which will be a dealbreaker for users with RDNA 3 GPUs who don't want to have better visuals without compromising much on performance vs FSR 3.1. Still, keep in mind that FSR 4.1.0 won't be natively available on RDNA 3 GPUs.
