I am not a know it all, but I do have a degree in psychology and we studied perception and sensation. Just a little fun FYI for everyone.
You say you have a degree in Psychology? Well you might want to actually brush up on Biology, because a psych degree has utterly nothing to do with how your brain works on a physical level.
Everyone has different thresholds in maximum discernible motion. There is utterly no such thing as 30 fps being the max that the eye can see. Why? Because the eyes don't work on the level of FPS. People are EASILY able to discern the difference between 30 fps, 60 fps, and 120 fps. Why? Because the interpolation of images that our eyes send to our brain from your monitor (and I thought you knew this because you had a degree in Psychology).
The more data that your brain is presented, the less your brain is having to essentially interpolate what is being shown. 30Hz means that every refresh cycle (generally on a level of 1 second), you are having the image refresh 30 times within that cycle. 60Hz, 60 refreshes within that cycle. 120Hz, 120 refreshes within that cycle.
You are literally being fed more information to your brain, so your brain is quite literally guessing less to perceive motion. That leads to better motion clarity (less motion blur), and a more enjoyable experience (my personal opinion, and many others).
Since you are in a STEM, I implore you to actually go out and do some research on the topic. Because right now, you are spouting the same stuff that Arxontas said about 2 weeks ago, which I had to get into literally the same argument.
And if you really want to get into actual Biology, there are approximately 1.2 million optic nerve fibers capable of carrying electrical pulses to our brain (in other words, information). And to say that a human can only discern 30/60 Hz is ridiculous. There literally is no limit.
And if you want to get even further into Biology, there are two ways your brain perceives motion. One is Global motion, in other words your brain tracks a large area. Or Local motion, in which your brain tracks a focused area. Of which viewing "motion" on a monitor falls in the latter.
And I beg you, please don't pull an Arxontas. I REALLY don't want to have the same argument again.
