How to check what ist he best polling rate for your PC?

"Yuval, not sure what OS you have. Check HERE for more info and some software to adjust your polling rate. Rememeber that windows by default limits USB update-rate, or polling rate to a mere 125hz(125 updates per second). Default USB mouse polling rate: 125 Hz = 8 milliseconds of latency

Increased polling rate: 1000 Hz = 1 milliseconds of latency

Typical monitor input lag: 5 ms to 30 ms

Typical monitor refresh rate: 60 Hz (16.6 ms per screen redraw)

Human response time* (from light hitting eye to hand movement): 120+ ms

So from the time your computer/video card renders an image to the time you click/move your mouse and your response reaches the CPU it is:

30 + 16.6 + 120 + 8 = 174.6 ms

It seems the relatively slow reaction times of humans, coupled with the fact that your monitor will never visually reflect changes faster than 60 Hz or 75 Hz, that there is absolutely no perceptible benefit to increased mouse polling rates. ;-) hope this helps, if not let us know...good luck"
