After a period of gameplay (10 minutes up to 30) my game freezes and I lose all game sound. If I alt tab out, ctrl alt delete to get task manager up and just tab through my open windows over and over eventually it gets out of its funk and lets me resume normal play without the application closing. I can then continue to play until it freezes again and the whole situation continues.
Because of this it doesnt properly crash and thus doesnt produce any crash error reports.
