Apple's white paper for their transparent optical mouse states, page 5, (in
the caption) "...the camera captures 1,500 images per second".  Whether the
clicking mechanism and the data transfer protocols can keep up is another
matter.  It is a USB mouse, though, so I can't imagine the CPU polls it.
The time resolution of the USB channel is what, sub-microsecond?  The
latency is probably very small too, as it was designed for devices that send
very short packets of data.
