When i play bf now my screen randomly gets black squares all over the screen like a checkerboard, this used to happen rarely before but now its more frequent
gfx: gtx560ti, latest beta driver 285.38, OC 950/2010
For some people, the beta drivers actually caused issues. Same for me..I'm running a GTX 460, I get green sheets of color across my screen once in a while. Try reverting to a stable Nvidia driver release (like 280.xx).
