The game doesn't last more than an hour without either freezing or crashing. I've tried everything I read online I changed the INumHWTThreads to 2 'and' 1 in different ocassions, activated ThreadedAI, Used the 4GB Patch enabler, tried running the game on Windows XP Service Pack 3 and 2, but nothing works. Hi! I'm facing a problem with Fallout 3 that I haven't been able to fix.
