Recently I decided to upgrade from my old gts 450 to a brand new gtx 660 ti, hoping that I'll finally be able enjoy the game with a stable 60fps, but things didn't turn out as I expected. I'm playing the game on High settings with Ubersampling and CDoF disabled and I manage to get a constant 60fps in relatively enclosed areas, but the minute I step into a wide open area(for example: the soldier's camp outside Triss's tent)my frames drop in the 30-40 range and go back up to 60 in cutscenes and when I enter another enclosed area.
My specs are:
OS:Windows 7 Professional SP1 64-bit
PSU:Fortron Aurum 700W 80plus GOLD
CPU:AMD Athlon II x4 645 3.1Ghz
GPU: Palit gtx 660 ti JETSTREAM 2GB
So, does anyone have any ideas what might be causing this? Could my GPU be faulty, or my CPU bottlenecking it? Or did I just have too high expectations overall? />/>
EDIT: Forgot to mention, just as an experiment tried playing the game on the lowest settings with pretty much everything disabled and got the same results.The tutorial area and the arena run just fine.
