Edit: and it hasn’t really been bad either. The shader compilation after every gfx driver update is a bit annoying. That’s about it.

If it’s shader compilation under Steam, turn it off in settings. With advancements in graphics drivers and Proton, it really isn’t needed anymore.

I disabled it about 12 months ago and haven’t noticed any difference in performance whatsoever.

NVIDIA user here, no issues to report under X11.
