I'm using Arch Linux 64bit and the 14.3 beta driver. I had problems before with older non-beta drivers with a fog effect for example in the/before the startmenu. With the older drivers, the game slowed down and almost freezed up, but I was able to skip this part and it was okay. Now with the 14.3 beta driver, my pc just freezes sometimes in the pre startmenu scene. And because I don't see the fog effect, I think, that it is the fog effect, that freezes my system. It appears at random between scenes and in this pre-startmenu scene.
