If a game comes with FSR out of the box use that tho. It will not scale stuff like the UI for instance, so you get the UI at native resolution, but the game is getting upscaled. If you use Gamescope for scaling it will scale the whole image and it’s limited to FSR1 while games can come with FSR2 or even 3 (I think 3 is just added frame generation on top which is only useful for playing at >60fps).
Gamescope’s a compositor made by valve that you can install and add as a launch argument to games. https://wiki.archlinux.org/title/Gamescope
Yeah, fsr’s basically the same thing as dlss, it’s a bit worse but it’s pretty close. You can also use it on nvdia cards.
