Final message from me about this: you are clearly not familiar with how visual processing works neurologically. That is fine. But please then drop any such arguments. You don't know what you are talking about. You don't understand the research you vaguely remember, and don't grasp why it's not relevant here. Just forget about it.
Neurology I only did some passing modules that had overlap, yes. Primarily focused on nerve structure and function, and how it all interacts with biochemistry, endocrinology, molecular biology, and the like. Meanwhile most of my work on the eye itself was actually focused on gene therapy for photoreceptor replacement in dry macular degeneration.
When it comes to the details of how efficiently the brain processes the input from those cells, there I defer to what I can find on pubmed from actual neurologists.
It would probably have helped if you had taken a moment to summarise why the facts we know about how outdated ideas about perception are wrong are not relevant to commonly trotted out falsehoods about upper limits of human perception that are straight up contradicted by literally the evidence of people's own eyes.
Like yes, obviously it's reductive to look at one aspect of this when we can certainly provably distinguish artifacts and flicker presented to us at far higher rates than we can make out distinct image details, so yes, naturally there's still a benefit to ever-increasing monitor refresh and the framerates we're outputting.
(FPS players who play games with a motion tracker in the minimap, for example, are going to notice it more, due to their constant saccades maintaining their spatial awareness) And as I said, subjectively of course, people who don't know what to look for aren't going to fully register that there's something they are missing and will be perfectly fine with whatever framerate they are used to.
Our eyesight doesn't operate on the same principles as the technologies we use for image generation, so it's all a matter of finding the best compromises we can for making something look comfortable for the widest range of people, and there's probably never going to be an entirely flawless display technology. Hell, even our eyes are making the best of what they had to work with. Point to the cephalopods on getting their retina in the right place.
Anyway, this
is off topic for actually discussing the two modes which is why I had gone back to the talk of Live, Legacy, and the impacts as regards Consoles, etc.
