I have had no problem yet. For me it works good. My gaming score is the same (3.1) but my aero score went from 3.2 to 3.7 so something went up :)
Only thing i have seen a problem with is Far Cry which has something wrong, it's like a white fog, probably a draw distance thing that is way to close, but there is no way to change it. Im trying to patch the game now and see if that works. Also my system tells me that i have dx11 so something u did is not correct. My guess is you installed it wrong in some way. -- INTEL 9xx SOLDIERS SANS FRONTIERS
