I'm shocked that group 2 exists at all. Just wave your mouse around and watch the cursor. Or open up quake and turn around while keeping your eye focused on a stationary object.
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.
