system spec;


i5 3750k (4.5GHz OC'd , stable 12 hours testes with prime)


AsusRock Extreme 4


XFX 7950 DD 3GB (OC'd to 1GHz Core clock and 1400 Mhz memory clock, stable testes in heaven 3.0 for 2 hours maxium settings) 


8GB corsair vengeance  (1600mhz default timings, stable same as cpu)


XFX 750W PSU (bronze rating)


Game is installed on a OZ SSD.




whilst playing the game i have noticed,using MSI afterburner, that my GPU usage never goes above 40 - 55 %.


The game will stay at out 57-60 FPS (60hz screen) but in what seems  random points (single player, haven't tried MP as this is not a fair fight ATM) the FPS will drop down to about 25-40.  it tends to be if i move the mouse around very quickly or look at areas, but it is hard to pin point. it does go back up to 57-60, if i stop or look away. Also the shadows aren't quite right , it's hard to say how, just that they aren't. I can take a SS if needed. 




I am currently on the latest driver for everything ( i mean everything inc BIOS). Is this game poorly optimized for AMD GFXs'?  Any ideas please post.
