Personally I would use the the logitech drivers for your mouse, yes it is true that you can modify a file and use the razor drivers for logitech mice but it's nothing special, if you want you can change these things in your registry if you really want too. There is also another great program out that's called "
USB Mouserate Switcher" Some people actually just leave the default software from microsoft as their drivers and find that it fits their needs, but it all depends on the user.
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. Make sure you do this in safemode.
Peace
