Pirasp@lemmy.world 3 months agoNot necessarily, modern having keyboards can operate at upwards of 1khz polling speed. The main difference is, that usb needs polling in the first place, whereas ps/2 is interrupt based.
That essentially means that ps/2 tells the computer “hey a key was just pressed” instantly and usb waits to be asked whether a key was pressed or not. If the latter is done often enough the difference becomes negligible.

Higher than that, I have a keyboard with 8000hz polling and a mouse with 4000hz polling. Anything over maybe 2k at most is hard to perceive, at least for me

I think a high polling rate matters more with N-key rollover (lots of successive keypress messages in one bunch), which in turn matters for some gaming scenarios.
