nvidia driver 295.73 and graphics problems

[Desertowl]

Hello all,

I recently updated to the latest nvidia drivers and all of a sudden artifacts begun to appear - black boxes over planes and black spots over the sea (those are the ones I encountered so far).
Also I experienced a CTD in single player, which is new to me (all of my other CTDs were during MP).
I had no graphics problems up until now - maybe the issue is SLI related?

system spec:
core I7 2600K
P67A-GD53
8GB DDR 3 ram
Geforce GTX 560 Ti X 2 - SLI mode
