Gaming on Wayland, or more specifically sway WM, broke for me when updating to nvidia drivers version 580.
Reverting to 570 fixed the problem.
Card: Nvidia RTX 3060 Ti
What exactly happened: some games wouldn’t launch at all (overwatch 2) while others had severe performance issues (Resident evil 5).
Those were the only two games I tried. Both ran through steam and Proton GE version 10.
Though I didn’t test extensively, both games seemed to work fine on Xorg with nvidia drivers 580. So this confirms it’s only problematic for Wayland.
Which distribution? Maybe its an issue with the packaging. 580 is the last version that supports the older 10xx cards and there were some packaging changes in Archlinux. Now your card is newer than that and should not be affected. But maybe your distribution made some changes to packaging that caused the issue?
It’s Gentoo. That could be possible, maybe something to do with the open vs non-open variant. I will look into it.
