I am looking to play a game with HDR and that requires Wayland, Plasma 6, an HDR display, Gamescope and ideally just a launch option (--hdr-enabled). How do I launch a game with Gamescope? I see the Gamescope tab in game settings but all it has is upscaling (The game has more up to date upscaling anyway) and FPS limits neither of which I want to use and seem to cause problems.
