I have been having a weird issue with Batman: AA since the 1.1 patch was installed. I use to run the PhysX at High with no issue, except during the second Scarecrow fight. I found out later the PhysX were running off my CPU, which explained the temp increase of my system during that fight....but to the point. Now when I am playing, everything runs great for a while. Then suddenly the game freaks out, turn black for a second or two and then minimizes itself. When I bring the game back up, the PhysX are broken (I hit a stack of papers on a desk, paper just hovers in place without falling). Anybody else have this issue and know how to correct it? I will test the PhysX at Low when I get off work and see if their is an issue with PhysX anywhere else.
