If you want low latency you really need to use USB3/USB-c. USB3 doesn't use polling like USB2. USB2 latency is measured in milliseconds. USB3 latency is measured in microseconds.
- Zolomon 6y agoFirst I thought of the message polling in Win32, then I realized you were talking about the hardware. Would have been fun otherwise. :)
- trishume 6y agoIf you use 1000hz polling like my latency tester and keyboard do the latency becomes less than 1ms which is pretty small compared to the other factors. See https://michael.stapelberg.ch/posts/2018-04-17-kinx-latency-measurement/ https://michael.stapelberg.ch/posts/2018-04-17-kinx-latency-... I'd optimize lots of other things like trying to avoid the compositor, higher refresh rate monitors and lower travel keys before I'd look at USB3.
