I was trying out FSR4 on my RX 6800 XT, Fedora 42. Works really well and it easily beats FSR3 in visuals even on Performance. It does have a significant performance hit vs FSR3 though but it still works out to be a bit faster than a native rendering on Quality.

there is a modified .dll you can use to replace the one in a game folder… AMD leaked it accidentally when they were releasing some open source stuff

I can send you a link tomorrow or upload it, Im not at my PC right now

edit:

here is link https://gofile.io/d/fiyGuj

you need to rename it to amd_fidelityfx_dx12.dll and replace the one in the game folder and it should work (in Cyberpunk). I had to use OptiScaler for Hogwards Legacy as just replacing the .dll made the game crash on launch and it was necessary to spoof it as DLSS

    I'll try this out tomorrow, thanks for the DLL.

    Have you tried any games with no official FSR4 support, like Grounded?

    Baldurs Gate 3 AFAIK does not officially support FSR4 and this works with it with OptiScaler (I've tried on Steam Deck). Wanted to try on PC as well but game has updated to the official Linux supported version and this does not work with it because it’s Vulkan only now. My internet is slow so I can’t be bothered to redownloadalmost 100GB just to downgrade the game version. Will have to probably check what’s in my library.
