tried BF3 with the cars at stock? on my 7970/7950 stock i get 91/98%. this was 1080 Ultra and 4MSAA. only 2 cores hit 90% the rest were 60 - 70%. hmmm. i was using 13.4, though. only recently moved to 13.11 for BF4 Beta. usage on that was very similar to BF3.
my fps at those settings did dip around 70 fps in BF3 MP 64.
edit: might as well ask . . . you have HT on, right?
