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.
It doesn’t even need to be Sways issue. What I mean are secondary issues like packaging of Sway or related packaged that are used when using Sway or Wayland. It doesn’t need to be a Wayland issue in itself. I just had in the past issues and quickly blamed something and it turned out something different.
