How to get rid of mouse acceleration completely for precision gaming

Follow aion's instructions on this Razer mouse topic and you will be making accurate movements and aiming with your mouse:

I'd enable "test signing" first, and then run the program in Safe Mode as an Administrator (right-click the program icon first and navigate the menu for this feature).

Sometimes going to Windows' mouse properties and disabling "mouse precision" isn't enough, your aim will still slightly accelerate and make you work harder to aim. That is why aion made this program. I hope y'all find this thing useful. It's a kernel program so it'll always run at boot-up.
