Hello, I think I know why the game freezes for some people.
I noticed the menu starts just fine, no crashes and whatnot. In fact, if I stayed at the menu, the game would run just fine for as long as I stayed there.
The catch is when the game fully starts in that room. It slows down but it doesn't freeze. If I move slowly, really slowly, I can walk around and twinkle the settings, it only freezes when I turn around.
What I think it can be is that maybe the program checks every couple of frames for certain objects or instances, and or perhaps it's all in one archive, which is put to much strain when the room loads.
At least, it is what I think it might be.
Sorry for the long message
