Sadly, I had to downgrade my drivers (7870XT) to 13.12. It seems to play the nicest with this game. Still get some micro-stutters and hitches, but it runs fairly smoothly. Tried every driver from 13.XX to the 14.12 Omega Drivers and none of them were worth a damn, except 13.12. So, if you have older hardware, try those, they seem to be the most reliable.
