Had stuttering for the first 30-40 minutes of playing, then switched "Lock Framerate" to off in the graphics settings. Stuttering went away but had horrible screen tearing. Changed vsync to adaptive in program settings for nvidia control panel, been playing the past 7 hours with smooth fps no screen tearing. Ultra preset, rig in profile. For sure the in-game vsync (Lock Framerate) was the culprit for my stuttering, I could feel the fps constantly spiking between 30 and 60. Weird.
