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.

The frame rate isnt going from 30 to 120 FPS. It's actually going from 30 to like 20. The rendered frames are different then the CPU frames which handles the game loops, (physics, input, simulation, etc)
