Just did some testing and performance is for sure much much improved even with full gameworks features enabled. That said smoke is still a fps killer. I tried my old 640 gt as a dedicated physx card and with full on gameworks effects the fps is less than half hovering between 24-30fps yet if i disable only smoke i actually gain around 10-15% against my 980ti handling physx alone.
Now i have a 560ti i would like to test but nope nvidia wont let me because noo wddm 2.0 drivers available for fermi .. thanks a lot
I'm getting on average around 80FPS with everything maxed at 1440P, As you have a 980 Ti as well you should be getting a metric butt ton more frames, Unless you're playing at 4K ?
