My 2GB card pulls locked 60 FPS, a GTX 760 2GB.
Suuuuure it does. Suuure. I highly doubt a 2GB card gets 60 FPS constant and not 15-30 FPS constant.
I had to tweak down clouds and some effects, but texture and model detail is on ultra. I get 60s with VERY few dips to 50s(I don't even feel it slowing down to 50s).
