In No Remorse, some of the animations seem to be frozen - steam (and flame) jets coming out of pipes appear to be frozen (and disappear instantly after two seconds when a valve is turned), spider mines float in mid-air motionless instead of walking like a spider, and fans (the ones in the wall that blow you off platforms) don't seem to move at all, even though they actually work.

I tried switching around graphic modes in the setup but it didn't help. Any ideas on what could be causing this?

I've looked at lets plays on youtube and all of them had working animations. Here's an example: http://www.youtube.com/watch?v=WIJXiM7yFyM&t=0m16s

What gives? Could it be because they're playing the CD version?

EDIT: I'm a fucking idiot. "Animations" was turned off in the in-game options menu.
