I have a problem with crysis 2, I can run the game and play for awhile but after about a minute of play the screen will go black.
I can still see the HUD and the game is generally still working(audio works, I can hear myself moving and see subtitles) but I cannot see a thing unless I change the resolution/vsync settings (by turning it off, then on again) and then I can see again but only for another minute, I can also alt tab back to the desktop which also allows the visuals to return but as I said, only for a moment!
My rig is
Windows 7 64
Intel Core 2 6600 @ 2.4 GHz
4 GB Ram
Nvidia GeForce 7950 GT ( a message pops up at the start of the game saying unsupported graphics card, don't know if that helps but when I googled the problem allot of the results said it didn't mean much)
I have already made sure that my drivers and the game is up to date.
What could be the issue?
