Yep it's very obvious when moving the cursor in a circle since you can see every frame.

I'm sure group 2 exists. It's just that all its members have an undiagnosed vision disorder.

There are also people who can't really focus on moving objects very well. They generally look extremely blurry to me even if moving relatively slow.

A few years ago e.g. the Simpsons began to use these computer aided 3-d pans which hurt my eyes to watch. Pausing, they are all in normal resolution but when watching them the screen turns into a mush for me and I can just see color blobs.

I just realized that I literally never do this. It is indeed incredibly jarring. even at 60Hz. I think my eyes basically immediately "jump" to where I want to move the cursor, so I don't really "track" it. Do other people track the cursor with their eyes?

My eyes naturally snap to moving objects and track them. And even if I only look at the spot where I want the cursor to be, I can still see it moving and leaving frames behind in my periphery. And that's at 144hz. I'm thinking of getting a 240hz or 390hz soon though.
