I tried Wayland again on my Vega and I see that the input delay dilemma is solved, but I do want to buy a new GPU and thinking Nvidia. Also a year ago I tried a GT 710 I had to see if the situation was that bad with general support. Since then I have seen that the situation is way better now. Last time I had Nvidia on Linux(for games) was with the GTX 800m series years ago and that was obviously on Xorg. What is the experience with RTX cards gaming on Wayland right now?
Update: Steam flickering went away with turning off GPU acceleration for web content. Both CS2 and OW2 run smooth ~200-300 FPS on “High” preset. They both have some flickering in menus but not in game. (1980x1080@144Hz, nvidia 545.29.06)
another update: switching sddm to use Wayland(Weston) instead of X11 seems to make everything just a little bit smoother and better. (no measurements or facts, just a feeling)
