Me too I'm suffering from the random static noise that is quite disturbing.
I read a post from Dex relating it to Intel core 2 duo,which seems relevant because I have that in my pc.He advises to choose to run the game with 1 cpu only.The problem is that he instructs to use the ingame task manager to do this and I can't find how I should proceed to do that.I went to options but did not find it there.So how do I access this task manager?
