Arma 3 Alpha goes to a black screen after playing for about 5 minutes. Can still hear audio in the background but no video and no escape. My system specs are: CPU - Phenom II 965 Video card - Radeon 6850 Turned my video settings down and it runs longer but I am just trying to figure if this is something to do with my settings or if I have a problem with my video card. Please help, appreciate any given.

Monitor goes black, no message. Really leaning toward believing the graphics card is overheating. Don't know enough about this stuff, but am hoping there is maybe a fail safe shutdown for my card when it reaches a certain temp?

I just have a speaker setup right now. Digital audio (S/PDIF).
