So yeah short story: i get between 10-20 fps less in areas where i got rocksolid +60 fps prepatch. And even still, when i am playing @ 60 fps (measured with msi afterburner), (for ex. indoor areas) the whole game still feels super laggy/ jittery, never had that prepatch, always got 60 fps rocksolid (vsync) , only exception was when i was fighting with more then 10 enemies at the same time or something like that, but now i'm playing with 10-20 fps less in general.

Specs: I7-920 OC'd -3.5
AMD HD 6950 OC'd
6 gig ram DDR3 OC'd
Win 7 - 64 bit
AMD Drivers: 12.4

Didn't change any of my mods/or downloaded new ones. The whole game feels laggy as [censored] right now.

Anyone here knows what goin on/ has some interesting ideas about it?
