I don't know? Sometimes I also have issues where the perspective correction stops working and I see the image of each eye individually, with blind dot and perspective issues at the same time. But luckily only if I'm very tired.
Maybe something's wrong with my mind? But 24/25Hz, even with the correct shutter speed, is noticeably causing strain to process, while e.g. old school TV productions at 50Hz don't have that issue.
So you're able to interpret individual frame transitions at 24 frames a second? You've been unable to watch the vast majority of movies created in the last century as they strain your eyes? Maybe you need to get your bionic eye recalibrated?
Why would playing high frame rate games alter your vision? Is your brain reprogrammed when viewing image transitions at frame rates so high that they cant even be noticed.
Further research needed probably. But it doesn't seem to be far fetched to guess that what you do influences how you work.
I think you can notice high frame rates. Difference between 60 and 120 fps is striking. Even between 90 and 120. And everyone I was showing my phone that does 60, 90 or 120Hz could see it.
Conversely I don't see much difference between 120 and 240 fps.
Because it provides a different perspective, figuratively. I think that might also be a reason why HFR movies feel weird for some people, it's very much a comfort zone.
