So I did a bit of testing with the Adaptive VSync, and well, YMMV. You may need to turn the frame limiter off for it to actually do anything. What I noticed is that as soon as I turned the frame limiter off, it smoothed out a little, but it created a strange panning-wobble that I found distracting. So make sure to test that with the frame limiter on or off, as it may depend on your monitor's response time. I normally just run it at 60fps limited.
