Hello I have a gaming mouse that has a max DPI of 2000, and the DPI switch only changes it from 1000-1600-2000 but I want 400dpi, because I want to find my perfect sensitivity on cs go, is there a way to do this? (Tecknet m268 mouse) I tried finding if I can but all I see is mouse speed on windows 8 🙁 Thanks for your time.
