When you set 85 Hz, flickering becomes bearable, but still noticeable. When you set your refrest rate on such monitor to 60 Hz, you can clearly see extreme flickering. Most good CRT monitors used to show 85-120 Hz. In dynamic scenes CRT and LCD monitors are similar in this regard. CRT monitors are good for this because their image is fully dynamic, that is every frame is drawn from scratch, while LCD monitors do not effectively draw frames that are not very different from each other, they only draw the difference. On such monitor, even if your game has 1000 FPS, you will still essentially see 60 FPS. On such monitor, no matter how much FPS your application, such as video game, has, you will see only 60 Hz, and additional frames will be ignored. Myth about "60 FPS" came from in the first place? Most LCD monitors today, let alone 10 years ago, have refresh rate of 60 Hz. Trained fighter pilots can see even more, so training of the brain might just be possible in perceiving a lower threshold of temporal gap Than 50% of the population will benefit greatly from FPS of 45+. New conclusion: By far most of the human population (test in USA) will see more than 24 fps, only the extremes will see just the 24 fps or less (we're going towards visualle impaired elderly). When I wrote my replies and the first post, I did not know about this research. But on the other hand, you have 25% of the population who will percieve more than 60 frames per second, with extremes going to seeing temporal gaps of up to 2 ms.
The average population would perceive about 45 frames per second (nice going HFR movies). Edit2: Seeing that my post is the 2nd hit on google when looking for 'max frames per second eye can see', little add-on: This research went looking for the temporal gaps that people could perceive, I'm linking to the result diagram. That's right: 255 frames per second And they could give a rough estimate as to what they've seen.Įdit: seanalltogether took the time to post a source (220 fps and they could identify the aircraft). Fighter pilots have been recorded spotting 1/255th of a frame. It all depends on the training a person has had. Academic courses on cognitive neuroscience at the university of Utrecht (Netherlands).
