Yes, I have Nvida drivers installed and yes my settings look like yours...with all this my mind keeps going back to heat....Next thing I'm going to do is get two things...one of those little computer vaccum cleaners and a clip on fan that I can clip on the leg of my desk and aim at the computer...if that doesn't work then I am totally stumped...also posting on the tech sections of the game forums...see if I get any ideas from their people....thanks again so much technobeast. I'll let you know what/if they say anything other than what we've discussed
