Fallout 3 appears to crash with quadcore CPUs and Windows 7. Quadcore + Vista and it runs fine.
I've got it stable - but I have to run everything stock. The engine polls the CPU for timing, so if you overclock, it throws the timing off and the game crashes.
I had been running stock because of this, and fired up Metro to have it stutter and chug along...
My mobo allows me to save OC profiles, so a quick reboot and all was well.
