@8Ataco said in Quake 3 mouse lag:

My mouse for my pi 4 has a lot of lag in quake 3 but not in other games like quake 1 and 2 anyone know a fix

Try and turn up your mouse sensitivity ingame... also run "/cg_drawfps 1" in the console and make sure that you are running a solid 60fps. If the game is not running a solid 60fps this could be where your lag is coming from.
