I can't keep the game running for more than 10 minutes or so. I have a GTX670 as primary video card and a GTX560 as a dedicated physX card. I am using driver version 314.07 and it crashes, recovers and then the client remains a black screen although I can still hear the game running. I am forced to minimize the client and close it. I believe I was reading that the physX might have some issues with Arma 2 and so I'm thinking of unplugging the card altogether and seeing if that might solve the problem. Any help is appreciated!
