545.29.06 fixed that for me on Counter-Strike 2 at least

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)

Im on Arch and Sway so no thoughts about Gnome or KDE. GWE does not work on Wayland. I do some fan settings with nvidia-settings on commandline. We are desperately missing fancontrol etc on Wayland for nvidia.

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)

I haven’t fixed it, it mostly goes away on its own after a while. And It doesn’t bother me that much as I switch to another workspace when not playing anything.

It’s OK. Most of my minor problems seem to do with XWayland: Steam UI flickers sometimes, some games get confused about which display they are on and mess up their resolution/position, sometimes games have some stuttering when not in fullscreen. All of these are somewhat annoying but easily mitigated or fixed. Performance feels good and everything is smooth. eg Skyrim, LOTRO etc. I haven’t tried any games that demand very high and stable FPS for a while. (RTX 2070, sway, arch)
