I tried forcing vsync off in the nvidia control panel, but no, that's not it. Besides it doesn't feel like vsync, it feels like mouse smoothing.Phobos Anomaly wrote: Your description sounds like what I feel when moving the camera around in a game with V-sync on.
I made a video of the issue here:

It wasn't that visible at full speed, so I slowed it down to 20%, which is why the fps is a little choppy. In the video I move the mouse back and forth with constant speed. You can however see that the speed isn't constant and towards the end of each movement (left/right), there is a visible "slowing down" for a second or so (remember 20% real time speed).
