The driver Synapse 2.0 (download from the website of Razer) does its job, with a very good editor macros and especially the ability to override the clean Windows mouse acceleration screaming so many gamers, especially the Osu players high level. This is also where the main advantage of this mouse on my RAT5 whose driver is really bad.
EDIT: as I thought, you get very quickly to the shape of the mouse, even after having played for almost a year with Cyborg RAT
I therefore recommend for players seeking the absolute accuracy of the sensor first. For those who prefer the comfort and play games like FPS / RTS, I recommend the RAT5 / 7, the sensor is perfectly sufficient, and more pleasant handling.
The Synapse 2.0 software appears to remove the mouse acceleration regardless of the device used. I advise players to download it anyway to be able to get rid of this gene. However, I am not sure that the tab for doing so is available without a Razer has been connected at least once.
