Yea, I ran into this problem again at the Dzemael Darkhold with the gate opening cutscene and added it to my original post here. I've noticed that when the bug happens everything on my PC is lagged up affecting everything from minimizing the app or moving a moving a folder window around the screen. I'm start to think this may be a problem with the game application itself rather than an in-game bug. 
What are your system specs Leknaat? Maybe we'll find some similarities with our PCs.
