I don’t share this experience, I’m using an Nvidia 3090 GPU on KDE, and performance with Wayland is very poor, less than 60fps no matter OpenGL or Vulkan.
As far as I can tell 26.2 is forced Wayland, there’s no way to switch back to X11, and even if I use a Flatpak launcher and disable Wayland, it crashes instead of falling back. 26.1.2 runs perfectly fine, but If I enable Wayland performance is poor again.
Could you add a PREFER_X11 option to switch back to X11? or detect Nvidia GPUs and switch back?
I somewhat share this experience.
26.2 by default now uses Wayland instead of X11, and I can’t find a way to switch back, but performance is MUCH worse on Wayland than X11 no matter OpenGL or Vulkan, I can test back and forth on 26.1.2 with the PREFER_WAYLAND flag, but 26.2 I can’t go back to X11, so I can’t play 26.2 above ~60fps (its not a vsync issue, its just bad performance, it fluctuates above and below 60)
