That was just caused by me not processing input properly. I've set up a proper rendering loop here and now only render the most recent mouse position on each frame: http://jsfiddle.net/eymAS/84/ http://jsfiddle.net/eymAS/84/ It's better, but still limited to 60fps, and since I render to the state at 0s, the worst delay we can see is ~16.6ms + rendering time.
