Getting 50 fps w/ gameworks and 85 fps without. GTX 970 + FX 8350 here.
You can change the framerate on the .ini file.
It runs and looks better than the Witcher 3, I don't see the issue here, it's obvious it was going to be a heavy game.
Edit - playing at 1080p. And it runs slightly worse in-game than in the benchmark, but not much.
