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.

Nice! A big improvement indeed.

I wished you had showed them with similar sharpness settings though. The FSR 3 image is very oversharpened, while the FSR 4 one has the opposite problem so you can't really compare any details.

I've only noticed that sharpness was not the same after I've uploaded the video. Sorry.
