I never worry about motion blur, because I turn it off. The stupidest effect ever. If I walk around I don't see motion blur. Cameras see motion blur because of shutter speed, not the human eye.
Umm, well, there is something like motion blur experienced by humans, in fact, your brain creates the time bending effect based on picture 1 and picture 2

There is a trick where you watch a clock that counts seconds and turn your head fastly away and back there (or something like that) and you will see, that the rate of seconds seem to be inconsistent
See "1. CHRONOSTASIS" https://bigthink.com/neuropsych/time-illusions/
Alright. I didn't know, thanks. Though the human motion blur is vastly different to camera blur in my experience. And games that have motion blur look really unnatural.
More realistic blur smudges things based on how the object is moving rather than how the camera is moving. For example, Doom Eternal applies some blur to the spinning barrels and the ejected shells on the chaingun while it's firing, but doesn't blur the world while you're sprinting.
Yup this is called per-object motion blur and is more common in modern games. I'm still not that big of a fan but I've heard good things about it from other high framerate enjoyers
I don’t know if there is scientific proof that every human experiences "motion bur" the same way. I would bet not.
On the other hand, humans don't see in defined frames. The signals aren't synchronized. So a big part of perceived blurring is that the succession of signals isn't forming a single focused image. There isn't really a picture 1 and 2 for your brain to process discreetly. And different regions in your vision are more sensitive to small changes than others.
A faster refresh rate is always "better" for the human eye, but you'll need higher and higher panel brightness to have a measurable reaction time difference.
But hitting really high refresh rates requires too many other compromises on image quality, so I won't personally be paying a large premium for anything more than a 120hz display for the time being.
I agree, human eyes register only change in light in an analog style way (no framerate more something like waves as I understood) compared to cameras, which register all light on every frame. I simplified that part with the "pictures" because I thought it was more understandable like that I guess better would have been something like „your eyes kinda shut down during fast movements of the head and your brain makes up for that by generating a nice transition“
Motion blur in games gives me bad motion sickness and garbles what I'm seeing. I already have a hard enough time processing information fast enough in any kind of fast paced game I don't need things to be visually ambiguous on top of that
