Performance, even though the framerate is all over the place.
Would have stuck with resolution if the game actually ran a locked 30 though, but it doesn't.
Judder at 3X-5X FPS>Judder at 2X-30 FPS.
Yeah I just started playing yesterday. Been playing in prefer resolution and it definitely feels like its not a constant 30fps, especially noticeable when moving the camera around. I'll have to try performance mode
