This is making me wonder: Thinking about Dan Luu's research on latency of modern systems (https://danluu.com/input-lag/), what is the minimum latency one could get in a modern system (e.g, USB keyboard, modern display hardware)?

Display refresh had never gotten much faster than 100hz or so, so that will be your limit. USB, even terrible implementations thereof, is much faster.

144Hz refresh is rapidly growing more and more common as displays become easier to drive. I'm sure the market penetration isn't as high as 4K screens, but I'm confident in it being the 2nd most popular refresh rate after 60Hz. I really refuse to work on 60Hz at this point. I notice significantly more eyestrain on lower refresh rate displays. Switching form a 144Hz display to a 60Hz feels noticeably worse.
