Turn your OC down , UE3 is all CPU . It is a well threaded engine but ,is not known for OC stability. shrug
That's my only guess
Batman AA is amongh the most solidly built, stable as all hell games I've ever played. It never chugged, it never stuttered, and it certainly never crashed through the roughly 12-14 hours I got out of it. Amazingly stable, I wish every game ran this way.
Yep, I had issues. Turn off PhysX until you make it through the areas that are crashing for you. There were two in particular that would crash every time in my case.
I just played through this game (it was surprisingly short...) with PhysX on 'high' the whole way through, and it didn't crash or stutter even once.
Doesn't mean those problems don't exist with some video cards and drivers. They do, and there are pages of forum posts on the matter.
