IF YOU'RE USING AN ATI/AMD CARD
It seems that this is an issue was caused by the changes made to the drivers from AMD, but was fixed in a driver version introduced in Q2 2014..
Please install the newest driver package:
If that doesn't help, please revert to 13.4 or older, if your hardware permits this (of course you should go back to the newest drivers once you finish this game):
Catalyst 13.4 64-bit
Catalyst 13.4 32-bit
IF YOU'RE USING WINDOWS 7, but don't have an ATI/AMD card
