Oh wow, that would drive me mad. That's one of those subtle human-machine interaction problems where sometimes people don't believe you (and maybe you start to doubt yourself even). And then people start throwing around studies saying humans don't perceive this or that under some millisecond threshold or whatever. Before high refresh rate screens, I was one of those people that would turn off v-sync in games because the additional input lag bugged me just enough, JUST on the edge of perception. I wasn't even a competitive player or particularly good, but it felt....mushy. Similar problem with playing old NES games on modern LEDs. For many years I had a mechanical keyboard I loved, but slowly and subtly over time the enter key would miss a keystroke. It was like 1 out of 300 times maybe, but it was just often enough for me to start doubting my own fingers. Finally couldn't take it anymore and just bought a new keyboard. Just goes to show that very subtle problems in a computer interfaces can have a big impact.
