So I'm at the final part of the game. During the final 2 or 3 cutscenes (the pre-rendered,NOT ingame), I get the error "unknown fatal exception" and the game crashes. I can skip them and continue without problems but still...
I find it weird that it didn't happen in any of the previous cutscenes.

My temporary fix is: On Windows 7, when I change the driver from "primary display driver" to my specific geforce card (or vice versa) under the advanced graphics option right before a cutscene, it will play without crashing. I have to do this often, though. It doesnt stay working that way.
