|USB Port Speed|
To complicate things a cilantro further, several readers / gamers have pointed out that it was possible to overclock a USB port. That needs some explanation. A USB port under Windows polls 125 times per second, meaning that the mouse can transmit its location 125 times in a second. The port has a clock speed of 125 Hz. With the increased precision of these three mice, it's also possible to increase their speed of movement (cpi, for counts per inch). Remember that this is the number of measurements made - or pictures taken, if you prefer - per inch traversed. At a speed of 800 cpi, it does seem that the 125 Hz speed of the USB port would be a limiting factor that would make the mouse less pleasant to use, since it would lack reference coordinates. That affects the regularity of its movement. However, it is possible to speed up the USB port, either via a small software program or by changing a system file. The problem is that it also affects the stability of the system. On some PCs, you can increase the speed to 250 Hz, and on others to 500 or more. But the acceleration can cause crashes and blue screens, requiring you to reboot in protected mode. Also, other random USB peripherals don't support acceleration. We can't recommend doing it, but it's up to you.
Still, for mice like the MX 1000, the MX 510 and the Razer Viper, overclocking can increase comfort and precision. And in this area, the MX 1000 is handicapped. Since it uses Fast RF wireless, its transmissions have a ceiling of 150 Hz regardless of the acceleration of the port. On the other hand, the MX 510 does benefit from the acceleration, and the Viper even more. If you use 500 Hz and re-test, you find that the MX 510 comes dangerously close to the MX 1000 in terms of precision, and the Viper even closer. However, it's not enough to close the gap with the MX 1000. Conclusion: Gamers who want to play around with overclocking might do well to wait for a wired laser mouse!
So, how do you go on increasing the mouserate? Fret not, you need not be a tech guru to do so. There's an easy-to-use USB Mouserate Switcher which you can download from . The USB Mouserate Switcher lets you enforce a mouse polling rate of 250 Hz (4 ms), 500 Hz (2 ms) or 1000 Hz (1 ms) and lets you restore Windows' original "usbport.sys" (8 ms) if needed. Please note that increasing the USB mouserate may affect system stability, so experiment with the different mouserates and see which of them suits your system best.
Enjoy your mouse "upgrade" and may your frag count increase!
Note: Switch your mouserate at your own risk!
