Well, I installed the game again (don't really play it much after seeing the cheesy end, that and having to play the game with no speech, as the language is quite bad in it).
Basically, for some weird reason, anti-aliasing kept sticking and wouldn't turn off, in-game or even when I forced it off in the control panel (158.22 WHQL / XP32 driver here). So basically, got up from my PC while the benchmark ran, came back, and the program had froze. I tried it like 3-4 x, and anti-aliasing would still stay on and the shadows would flicker. I guess I gotta download all the patches again.
