FSR 2 compatibility using DXVK

[Franck-Nein]

While FSR 2.x is not compatible with DirectX 11, it is compatible with Vulkan, so it may be possible to use DXVK, which allows you to run DX11 games on Vulkan, to translate GTA 5's DirectX 11 graphics to Vulkan, enabling FSR 2.x support.
I know a similar approach has been used to enable FSR 2 on games that already have support for DLSS, for example in Diablo II: Resurrected you replace dxgi.dll, d3d11.dll and d3d12.dll with the ones from DXVK and VKD3D making the game use Vulkan (in this case It's used to spoof the GPU to a GeForce RTX 3080 to enable the DLSS 2 option on an AMD GPU), and replacing nvngx.dll and nvngx.ini with the ones from the Cyberpunk 2077 mod FidelityFx Super Resolution 2.1 - FPS boost mod

but is gta not cyberpunk ?

The mod works in Control, Metro Exodus: Enhanced Edition, Hogwarts Legacy, Atomic Heart, Returnal, Red Dead Redemption 2, A Plague Tale: Requiem, Horizon: Zero Dawn, Guardians of the Galaxy, Spider-man, etc

As far as I know, both DLSS and FSR dll are generic, you can usually replace the whatever version comes with a game with the one from a newer one to update it, and it should work as long as the mayor version is the same.
From the FSR Mod description (abridged):
"Both FSR 2 and Nvidia DLSS work very similar, both need similar data to work. NVIDIA publishes its DLSS implementation as a dll file. This allows us to simply replace it with our own that translates NVIDIA DLSS to FSR 2 commands, Wine or DXVK work similarly."
As long as a game has the nvngx.dll you should be able to install and use the Cyberpunk mod without making any other change to the game.

How to use it for FiveM pleas ? :)

wait. is it possible to swap DLLs for diffrent version like Forza Horizon 5's FSR for eaxmple? (just ignore the fact that FH5 has fsr2)

@Franck-Nein the problem with this, is that dxvk doesnt seems to (yet) work with gta 5, i've tried and i guess i should've backed up my d3d dlls from gta 5.

[Franck-Nein]

@ILyesMk2 You usually can, as long as you stay within the same mayor version it is likely to work, it may fail if you are downgrading to a version that doesn't support a feature the game relies on, but other than that, there should not ve any issue.

@MiRw3b I know I have played it on Linux, so it should work fine, also It has a GOLD rating on Protondb, maybe try using the most recent dxvk-gplasync or version 2.1 from https://gitlab.com/Ph42oN/dxvk-gplasync
Also, you should be able to delete the d3d DLL from the game's folder, and it should just use the ones on sytem32, if that fails, download the original dlls (Uploaded by me, so here are the Virus Total results)

do you think is possible to add frame generation ?
