This shows the flicker fusion as bottoming out just over 60Hz; this conflicts with the fact that a large fraction of the people I know can see flickering in fluorescent lights and CRTs at 60Hz. One roommate I had could tell if my monitor was below or above 72Hz (this is for a static image, so unrelated to FPS).
