Just did a long gaming session in BF3 and it only crashed once - I got a black screen from the game and I had to ALT+F4 out (this didn't happen at the start or end of the game, it just randomly crashed). I checked GPU-Z and the OC wasn't removed, and MSI AB said that the temps were 75c, so I'm pretty sure it couldn't have been my OC that caused it. But other than that, a lot of people are crashing in BF3 anyway and they say there is a "major" patch incoming next month.
Gameplay wise, the game felt very smooth as always, and I didn't notice much of a difference in terms of FPS or temps.
I also ran 3dmark06, 3dMark11 and Heaven 2.5 - my scores seemed higher also, pretty sweet. I'm currently at 950mhz on the core with my 580 Lightning, with the fans manually set to 60%.
So far, these drivers are looking alright Edited by Darco19 - 2/21/12 at 5:18pm
