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.
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.
