1ms of frame visibility time equals 1 pixel of display motion blur per 1000 pixels/second

This affects modern sample-and-hold displays such as LCD and OLED. All flicker-free displays are subject to a sample-and-hold effect that creates display motion blur.

1. Even at 0ms GtG response, most display motion blur is from eye tracking on sample-and-hold displays. (see related animation)
2. Double the motion speed doubles the amount of display motion blur.
3. Double the framerate halves the amount of display motion blur. (see related animation)
4. Item 2 and 3 cancel each other out, so all UFOs in this animation has same amount of motion blur from display persistence.

IMPORTANT: Educationally best viewed on a high refresh rate monitor (240 Hz+) with as fast pixel response as possible (1ms GtG or less, preferably OLED). At high frame rates, edge flicker of stutter blends into blur, like fast vibrating guitar or piano string. On a 240Hz, you will be comparing 240fps versus 120fps versus 60fps, which will all have visually identical display motion blur with this animation demo, assuming pixel response (including overdrive imperfections) are an insignificant fraction of a refresh cycle.
