- FSR IS BACK!!!
Huge shoutout/thank you to Ph42oN for completely rebasing, updating and combining all of the old FSR patches to make them compatible with Proton 8.

Additionally a bug was fixed by Ph42oN with fullscreen not working properly when fsr is disabled which was present in proton 7

proton-wine updated to latest git
Ok I found out what FSR is: AMD FidelityFX™ Super Resolution (FSR) uses cutting-edge upscaling technologies to help boost your framerates in select titles.
