see this - How to Properly Set Multiple Launch Options
my personal gamescope launch options:
gamescope -W 1920 -H 1080 -w 1920 -h 1080 -r 200 -o 60 -F fsr -S stretch -f --adaptive-sync --force-grab-cursor
same but for steam (steam overlay will not work because of LD_PRELOAD):
LD_PRELOAD="" gamescope -W 1920 -H 1080 -w 1920 -h 1080 -r 200 -o 60 -F fsr -S stretch -f --adaptive-sync --force-grab-cursor -- %command%
same but for TF2 (steam overlay will not work because of LD_PRELOAD):
LD_PRELOAD="" gamescope -W 1920 -H 1080 -w 1920 -h 1080 -r 200 -o 60 -F fsr -S stretch -f --adaptive-sync --force-grab-cursor -- %command% -novid -nojoy -nosteamcontroller -nohltv -particles 1
configure mangohud via goverlay to your favor
add mangohud to game launch options in steam:
mangohud %command%
or you can add the env var:
MANGOHUD=1 %command%
to use mangohud with gamescope you need to do it like this:
gamescope --mangoapp -- %command%
