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.
I recently upgraded from Linux Mint 21.3 to 22.2 and my login screen STILL shows the Wayland (Cinnamon) display manager as “experimental.” Wayland runs a lot smoother on 22.2 and it’s a lot less crash-ey, but I don’t think it’s ready for prime time, yet. (Your own mileage may vary.)
Ubuntu 25.10 + Wayland + Gnome 49 + Nvidia driver v580.95 (RTX 3070 Ti) works flawlessly for both gaming and normal apps.
