Thanks for the feedback. I got the latest DirectX and C++ updates yesterday, which fixed the majority of the problems I was having with Steam games, but did not fix these two in particular. I'll have to check whether I'm playing JC2 in dX 10 or 11 at the moment. If not set to dX 11, will definitely change it. Will also try reinstalling the most recent NVidia drivers to see if they have any effect. Thanks for the suggestions!
