I haven't had a problem with it at all on my PC version. My friend at work has it for ps3. He said after about 45 minutes he's getting that caching issue causing the framerate to take a nosedive. Looks like a slideshow from what he said. I never have that issue with the PC version. I do find the game quite fun. I am surprised there hasn't been an update to fix the framerate issue. Maybe they don't know how to fix it, or just don't care.
