suddenly my black ops is doing the same thing. so i exited out of gta, and went back into black ops. now something weird started to happen, suddenly all the objects in the game flicker, like let's say i'm in the car, and there is a mailbox on the road next to me and a building across the street, the mail box would flash black and then goes back, and one of the building does that too, and it's a non stop cycle, it just does it with everything. Now last thursday i was curious to see how this beast of a machine could handle GTA IV. never have i owned a computer that can do that. got it from amazon, and was happy installed black ops and all my other steam games and played them all on high settings.
