So I just get my brand new 15" MBP with 4GB RAM and 256MB GFX card, and I test my fave multiplayer Call of Duty 2, and it runs like silk at full rez on my Dell 24" at 1920x1600. Fantastic! Then I quit it, do a days work, and the next time I start it up, its running like a piece of crap! Totally unplayable, its like just skips twice a second. I've read that Apple have written some appauling NVIDIA drivers, which makes sense apart from the fact that it ran so well the first time? Anyone got any ideas on how to fix this issue?
