Allegedly there is a patch out or in the works because many people are having problems with it but, this is what I would do first.
Download the latest drivers
for Audio and Video from manufacturer and NOT from Windows Update (just driver
, not Catalyst). Save those drivers to a folder you can get to later on.
Uninstall the game and uninstall the drivers, restart in safe mode and run CCleaner just to get rid of any registry instances of the game and drivers... restart again.
Once you are back at your desktop, go to the folder where you have the drivers, right click each executable and Run as Administrator. Do not restart yet if possible. Do the same thing with the game and restart after the game is finished.
