Playing it with medium specs and things like sky and fog in low. Rt is off. Also decreased my screen resolution from 1440p to 1080p, followed the reddit guide, changed a few things in the nvidea control panel, nothing helped much. I get a lot of stuttering in those 2 areas when I run and turn the camera around fast, so I avoid doing that. Not the unplayable game I've seen some people complaining about, but not the smooth gameplay that I wanted. Everywhere else is fine with just a few stutters.
Meanwhile, the game has been cracked and seems to run better than the original..
