What is Polling Rate?

[UberPooner]

Hi, i have a razer copperhead. Under the config options there is an option for polling rate. i cant really tell the difference between the lowest one 125hz and the highest one 1000hz. what does it do?

As the name and options suggest, it's the number of times that the mouse or software (not sure which) will poll/check for something...probably the position or similar.

125Hz being 125 times a second, 1000Hz being 1000 times a second. Assuming that it's polling for position, 1000Hz will probably be insanely sensitive.
