The frequency of the motion processing is independent from the frequency of the wireless signal
Comment on How are wireless mice these days?

Shrug. Spec sheet says up to 4000dpi. That with 2.4Ghz seems like there should not be any kind of issue.

dpi (dots per inch) is a measurement of camera resolution, not of the speed of the sensor processing. So the full processing goes like this:
The optical sensor in the mouse takes an image at 4000dpi resolution 60 times per second (60 Hz). That information is then modulated onto a radio wave that swings up and down 2. 4 billion times per second (2.4 GHz) - but the information is still only sent 60 times per second, so less often than would be of a modern gaming screen updating 144 times per second.

Ah, ok. That makes sense. I never thought of the sensor as a camera.

Yes. It‘s an office mouse so maybe battery life is prioritized?
