    The page is actually a nice find. I tried it on my boring NGS mouse at work, and it gave me 124-125hz, so, should be good. Commented Nov 20, 2019 at 11:55
  • As an interesting aside, the integrated touch pad on my laptop has a polling rate of ~124Hz according to that tool, whereas my Bluetooth touch pad is reported at ~88Hz. Commented Nov 20, 2019 at 21:24

    I highly doubt that my graphics card takes 100ms to render a scene. Think about it: It would mean a constant 0.1 second delay for everything. Out goes my fancy 144Hz monitor. It's more like 7ms for a 144Hz monitor and 16ms for a 60Hz monitor (assuming maximum rendering time between frames). On a 100ms delay, it means a 144Hz monitor would refresh around 14 times before it would react to my input. Commented Nov 22, 2019 at 11:14

    @JeremiahBarrar I don't deem 144 fps to be particularly high. Usually I have around 200fps on most demanding games. However, 100ms rendering time would imply something around 10fps, which I would deem...not modern. Even for a 30fps monitor the graphics card has around 33 ms time to render the image.

    Delay is a measure of latency, not throughput. It can take 100ms from the time your mouse produces a click signal until the corresponding change is visible on your monitor even with a very high frame rate. Of course, the response delay can't be less than the frame render time, but it can definitely be more. It takes time for the signal to reach the USB controller, time for the controller to send an interrupt, time for the driver to read the change from memory, time for the event to propagate from the windowing system to the program, time for the program to act on the event, ...
