Gamemoderun is a game launch command that allows linux to prioritize the game that is being run and give it full performance. It is currently installed with proton and steam but due to weird Ubuntu install behavior, it is installed in the wrong folder. This can easily be fixed by creating a simlink between /usr/games/gamemoderun and /usr/bin/gamemoderun. It does need to be run with sudo but once run adding "gamemoderun %command%" to the launch options on steams enables it. Addiing this to launch options without the simlink just fails to launch a game.
