Dante's Inferno is not runnnig well

Does it influence the cpu is at 8/8? With God of War 3 in the cutscene I got above 60 fps, and in gameplay only 11 fps, I saw a test at Dante's Inferno that with a 2650 V2(8/16 Ivy Bridge,2.6-3.4 Ghz 95W TDP) if you got 60 FPS spiked, can this generational difference cause a gain of ~25 FPS?
