After a good bit of gameplay my computer audio and video will start lagging really bad and skipping. But when I exist out of the game my video goes back to normal but my audio still lags until I restart my computer. So far it happened in GTA 5. So it could just possibly be GTA 5. I dont think the temps are the problem cause I got a decent air cooler and my room is fairly cold.
