My Adventures with “4K” 2160p and Linux

So I think I've pinpointed the exact problem. There are two parts to moving a cursor to a click target: quickly moving the cursor in the target's general direction, and then slowly moving to its exact position. Both are much more unpleasant in 30fps.

Quickly moving in the target's general direction: it's a lot easier to track a 10x20 pixel cursor when it's jumping 150 pixels per frame than if it's jumping 300 pixels per frame. (These are my own numbers, judging by people's reactions to my mouse sensitivity settings, it's likely yours would be lower.)

Slowly moving to the target's exact position: if the click target is 8x7 pixels like HN's upvote button, I can't move any faster than 2-3 pixels per frame, which is obviously half as fast in 30fps as in 60fps.

Well, if you mouse that fast then your use-case is similar to the aforementioned twitch-based FPS games.

This is a pretty basic usability issue and one of the reasons we put clickable things on the edge of the screen if we can.
