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.

True, Ig I was trying to teach people about why FSR often causes input lag. If you are getting 120 real frames then yeah, it probably won't matter much, but if you are getting less then 60 real frames it's going to be a worse experience unless you are playing menu games or something.
