On a computer game you can spot the 240fps because of the intermediate frames when you have visual elements moving very quickly across the screen. It's not because of 'faster eyes' I don't think. Like when you move your mouse very quickly you'll see twice as many mouse cursors en route.
- tpxl 6y agoAfaik you can also detect images that are present for a millisecond (eg white screen with one black frame at 1000fps).
- 6nf 6y agoYou can detect very small numbers of photons (sometimes a single photon), your eyes don't care about the frame rate. The question is, can you tell the difference between 120FPS and 240FPS
- danwills 6y agoStill an excellent question! There's this (no proper references) that seems to suggest ppl lose the ability to make meaningful judgements about frame rate (or ~differentiate differences) after around 150fps: https://www.quora.com/What-is-the-highest-frame-rate-fps-that-can-be-recognized-by-human-perception-At-what-rate-do-we-essentially-stop-noticing-the-difference#:~:text=tl%3Bdr%3A%20The%20human%20eye,the%20way%20to%20150%20fps https://www.quora.com/What-is-the-highest-frame-rate-fps-tha....
- danwills 6y agoThis (150>120) seems to suggest that many people would be able to see (maybe it'd be better to call it "feel" the difference at this point) the difference between 120 and 240fps. but they most likely couldn't tell 150 from 240fps.
