Er ikke enig i at det er noen "gigantisk" forskjell mellom 60Hz og 120Hz. Kan virkelig ikke si at jeg ser noen forskjell mellom 60-90-120 Hz til og med i VR. Det er en svak følelse av at det er noe klarere syn, det kan dreie som at det er en annen skjerm med andre kvaliteter generelt og placebo. Poenget er vel at en 120Hz monitor ser bedre ut, men at det ikke spiller noen rolle om spillet kjører 60FPS på den 120Hz monitoren. Behovet for 60-120Hz i VR dreier seg om kvalme, det er en følelse og spesielt frame drops i enkelte krevende sekvenser under en viss Hz som er problemet, dvs. behovet for å konsistent ha over 60Hz. Men selve evnen til tracking av objekter skjer ved overraskende lav Hz/FPS.
"He explains to me that when we’re searching for and categorising elements as targets in a first person shooter, we’re tracking multiple targets, and detecting motion of small objects. “For example, if you take the motion detection of small object, what is the optimal temporal frequency of an object that you can detect?” And studies have found that the answer is between 7 and 13 Hz. After that, our sensitivity to movement drops significantly. “When you want to do visual search, or multiple visual tracking or just interpret motion direction, your brain will take only 13 images out of a second of continuous flow, so you will average the other images that are in between into one image.
Discovered by researcher Rufin vanRullen in 2010, this literally happens in our brains: you can see a steady 13 Hz pulse of activity in an EEG, and it’s further supported by the observation that we can also experience the ‘wagon wheel effect’ you get when you photograph footage of a spinning spoked object. Played back, footage can appear to show the object rotating in the opposite direction. “The brain does the same thing,” says Chopin. “You can see this without a camera. Given all the studies, we’re seeing no difference between 20hz and above. Let’s go to 24hz, which is movie industry standard. But I don’t see any point going above that.

He’s not saying that we can’t notice a difference between 20 Hz and 60 Hz footage. “Just because you can see the difference, it doesn’t mean you can be better in the game,” he says. “After 24 Hz you won’t get better, but you may have some phenomenological experience that is different.” There’s a difference, therefore, between effectiveness and experience."
Some people can perceive the flicker in a 50 or 60 Hz light source. Higher refresh rates reduce perceptible flicker.
We detect motion better at the periphery of our vision.
The way we perceive the flash of an image is different than how we perceive constant motion.
Gamers are more likely to have some of the most sensitive, trained eyes when it comes to perceiving changes in imagery."
Just because we can perceive the difference between framerates doesn't necessarily mean that perception impacts our reaction time."
