I think this was already posted, but I'll give it a shot anyway.
What is the link between Film Viewer and AH2? Any time I try to watch a film, and later start AH2 back up, the game reloads the cache folder. Just curious, seems kinda odd, thought I'd mention it. I don't know if anything bad can actually happen from reloading the cache folder, but I'm curious as to why the viewer makes the game think there has been a video settings change.
Cheers
