Hi guys. I bought HD7850 O.C. edition 2 gb once week ago. My CPU is q6600 @3.2 Ghz O.C., I was playing BF3 , 45-60 fps on ultra. And I bought BF4 but i can't play game. My fps is lower than 30 on medium,high settings. My friend who have hd7850 and q6600@2.6 Ghz as me playing bf4 , 40 fps on ultra settings and 45-50 fps on medium settings. What is the problem my system? And I have checked GPU-Z when I was playing BF4, My gpu load value is lower than %40 always.
