Gamescope
So I'm not sure where to put my gamescope command in game settings on Heroic. Everything I read says "Environment Variables", but if I use any of the boxes listed there (Variable, Wrapper, Game Arguments) the game refuses to launch. Even with Mangohud and GameMode disabled.
gamescope -U -w 1920 -h 1080 -W 3840 -H 2160 -f --
