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.
580 driver dropped support for my graphics card and blocked it from running.
