Got quite high and stable fps > 55 - 60- 70 most of the time, however gameplay is not fluid and looks like I would have 25 fps. If I put cap at 40 fps looks actually smoother than 60.
I have all on ultra, hair works off.
Im on 970 with hair works on and all on ultra except grass density and some other option i dont remember and the game is running as smooth as yennefer cheeks!
