I have this cheap gaming mouse http://www.aliexpress.com/item/5500-DPI-7-Button-LED-Optical-USB-Wired-Gaming-Mouse-Mice-For-Pro-Gamer/32271225444.html . It works pretty good but it came without settings software. Anyone knows a software to change the DPI settings? The mouse can be found re-branded like Natec Genesis GX77 or AULA Ghost Shark but I tried their software and it doesn't work. Can anyone help? Thanks.
