A friend is having problems with his new 8800GTS displaying patches of black on the ground while playing BF2. Looks like a shader issue due to drivers but could it also be heat? It was a new install and he says there were no old drivers to delete. Sorry I don't have his Forceware version or OS. I am beginning to suspect heat but there are no white artifacts present. At this point I was just wondering if someone has experienced this and their experience dealing with it. TIA
