I'm Running this Game with an AMD Phenom II X6 processor, with Ati HD 6850 graphics card and having the same problem. Sounds to me it's more of a software problem more so than hardware. Espcecially since it's not native to a specific type of processor, Mother board, OS, or Graphics card. The problem seems to be persistent no matter what machine your running.

I had even downgraded from windows 8 to windows 7 64 bit and did every possible form of troubleshooting. Problem still occured. I just hope there will be a patch whether it be from SE, microsoft, ati, or amd, etc.
