Ok, so, when I'm on the menu screen the music plays smoothly if I keep my curser/mouse still, but, when I move it, the music becomes choppy. Same in-game, replace music, with FPS. In-Game, I can move my guy around with WASD with no problems, but the moment I move my mouse, it freezes until the mouse stops moving.
I've made sure the correct games are mounted, as well that those games are up to date and working. I would appreciate the help CG, thanks.
