I use Wayland KDE but have shortcuts for Steam to launch within Gamescope [].

    # normal steam with experimental HDR enabled, native resolution for my laptop and 165hz refresh rate.
    alias steam 'steam-run gamescope -f --hdr-enabled -e -W 2560 -H 1440 -r 165 -- steam'

    # full screen gamepad ui
    alias steam_gamepadui 'steam-run gamescope -f --hdr-enabled -e -W 2560 -H 1440 -r 165 -- steam -gamepadui'

Computer is Asus G513qy, a a full AMD laptop with discrete graphics. Janky thermal design, no thunderbolt... so more like a stationary desktop. Wouldn't buy something like this again but for now it does the job and runs great with any modern distro.
