Okay so it seemingly works? I did notice that this one game didnt run but it had unique launch options so maybe thats why? (the others fixed by using the cachyOS proton version)
Assume all these args are also in launch args
args = [
“–output-width 2560”
“–nested-width 2560”
“–output-height 1440”
“–nested-height 1440”
“–expose-wayland”
“–force-grab-cursor”
“–adaptive-sync”
“–fullscreen”
];
PROTON_ENABLE_WAYLAND=1 PROTON_NO_WM_DECORATION=1 DXVK_HDR=1 LD_PRELOAD=“” gamescope --hdr-enabled – env LD_PRELOAD=“$LD_PRELOAD” gamemoderun %command%
Either way it seems to work, so that’s fortunate ^~^ (removing PROTON_ENABLE_WAYLAND=1 PROTON_NO_WM_DECORATION=1 fixes it)
