Latency study 09a

Move the mouse. Click and hold anywhere.

In 09a, holding down the mouse button decreases frame rate — or increases traditional latency — non-uniformly. Cursors with more delay have higher frame rates making them move smoothly, while those with less delay have lower frame rates; their movement stuttering. Once the mouse is pressed and held, to me it appears that the smoother moving cursors draw attention to themselves despite being clearly separate from input.
