The brain and NOT the eye, does the seeing

The eye TRANSMITS information to the brain, but some characteristics of the signal are lost or altered in the process.

For example, the retina is capable of following lights which flash at a rapid rate. Temple Grandin, in her book “Thinking in Pictures” describes the case of an autistic woman who COULD actually see 60 cycle alternation of the lights in her house. Of course this was enormously distracting and interfered with her function. She typically screamed her head off when anyone turned on the light in her family’s bright yellow kitchen .

For most of us, the 60 cycle alternation is lost somewhere between the eye and the brain (called Critical Flicker Fusion- CFF) .

To further complicate the issue, the ability to process flicker itself is not uniform across the retina. The periphery is sensitive to large flickering lights and can follow them at fairly rapid rates. whereas the fovea is less sensitive to flicker and prefers smaller objects. In addition, the illumination level (I) around which the light is flickering,and the depth of the flicker (delta I) (e.g. alternating from very bright to very dark as opposed to just a little brighter and a little darker than the average luminescence level) are all important determinants.

The visual system has a preference for flash rates of 10 Hz (brightness appears to be enhanced when a light is flashed at this frequency. You can see this in the above figure which, regardless of luminescence level, peaks at that frequency

So I’m going to guess that the recommendations of the gamers has more to do with the fidelity of the electronics than features of the visual system.
