Doom 3

Hahaha, the fucker runs. They just didn't test the game on a system crappy enough.

1.4 ghz = above minimum.
256 mb ram = below minimum (384 mb)
geforce 2 mx-400 (32 mb) = FAR below minimum, especially since it's a MX card (64 mb)

Well, I have to play with lowest settings, and two parts of the game lag like hell. Loading a new level takes 2-3 minutes, and opening a door takes roughly 5 seconds, but otherwise, it's playable.
