Sure thing! Here's an example command line
(from Steam):
env DXVK_ASYNC=1 SDL_VIDEODRIVER=x11 gamemoderun taskset --cpu-list 0-7,16-23 gamescope -W 3840 -H 2160 -r 160 -o 160 --borderless --fullscreen --rt --steam -- %command%
Gamescope has become odd with the introduction of
'--expose-wayland'.
I think the 'SDL_VIDEODRIVER=x11' part may be key; I didn't need this before, but now I often do. Not every game requires it. It's weird.
It helps if something crashes because "wayland isn't available". Adding '|& tee /tmp/game.log' is useful for debugging.
Pinning (taskset)/gamemode stuff left for context. This example gives a game the cache-rich threads on a 7950X3D.
Beyond '--adaptive-sync'... I believe VRR calls for the feature to be enabled on the output in Sway.
See 'man 5 sway-output', looking for 'adaptive_sync' for more info on that
edit: One last note. I'm on Fedora - the libraries here are so new that Flatpak-based Steam tends to work best.
