The game works now with 64bit version, bug is solved. Thanks for pointing out bezvolos.

Hi, bought the game yesterday. Sadly i got this bug too, where the game stops loading textures properly and fps drops to like 2-5.
I can fix it with changing shadows from very low to very high (the game just reloads textures i guess).
Shouldnt it be relatively easy to fix this, since you know the bug fixes itself when changing various graphic settings?

Ordered win8 64bit, wanted to upgrade anyway. Have win 7 32 bit right now. Cant really play with that bug. Ill report back as soon as i tried playing with the new windows.
