: Human vision does not have properties like frame rate, latency, resolution, et al.
https://skeptics.stackexchange.com/questions/3348/can-the-human-eye-distinguish-frame-rates-above-60-hzYou'd be hard pressed to get 60fps out of the human eye.
In laboratory conditions, it takes around 150 ms for neurons in the visual system to begin to recognize and categorize a newly appearing visual input.
However, this little factoid is not the frame rate specification for human vision.
If real-world perception were to follow this same pattern, then for a considerable time after each saccade we would still be perceiving the old retinal input, rather than the information currently on the retina. In fact, we should have to wait around 150 ms to ‘see’ what is in front of our eyes after each saccade, by which time the oculomotor system has already begun to choose the next saccadic target.
That would suck.
Fortunately, the human eye is more than a camera* with fat pipe connection to the brain.
While holding a pen, for example, the sensory input is limited to the receptors of a few fingers, leaving the majority of the surface of the pen outside of our direct sensory range. Nonetheless, we perceive a complete object, not a pen with holes where our fingers do not touch. Similarly, our visual system actively perceives the world by pointing the fovea, the area of the retina where resolution is best, towards a single part of the scene at a time.
Human vision does not have properties like frame rate, latency, resolution, et al.
Visual constancy can also be viewed as a temporal phenomenon: objects appear to be continuously present over time. Yet the duration of external events are typically longer than that of a single sensory ‘sample’ such as a fixation. Although movements of the eyes, head and body disrupt our steady access to these objects and events, the stream of consciousness continues smoothly across these sensory disruptions. This is an amazing feat, given that each saccadic eye movement creates a temporal disruption in the flow of information from the retina to higher perceptual areas. The motor smear on the retina during the saccade is suppressed, making us largely unaware of the retinal stimulation during this time period. In addition, each saccade requires the visual system to ‘re-perceive’ the information from a new fixation.
Time is relative...
...perceived time seems to shift forward, towards the beginning of the new fixation, essentially compressing the time immediately before and during the saccadic eye movement. One possible interpretation is that space and time are inextricably linked in the brain, with the pattern of strange perceptual effects reported for stimuli flashed around the time of saccades reflecting a spatio-temporal transformation between fixations.
The Bottom Line...
Human vision is not bound by frame rate.

Good points but this is their take.
