normally mice that have adjustable dpi (like Razor and such) have a resident software running on the taskbar that you can adjust the dpip depending on what your using the mice for. (gaming etc.)
found numerous forums mentioning the software I speak of is on a disk (*cd or dvd I assume*) did you install it ?
Sadly, when I got it my pc was a bit broken and couldn't take discs, so I assumed I didn't need it and now I'm not sure where it is D) so if there is a way to get the software online I would be happy to know, as I could personally not find it
have you tried using http/adx-mouse-setting-program.software.informer.com/
I don't know if i'm an idiot or something might be wrong, but the download link doesn't do anything, it only links me to a site and it's not the download site (Unless I'm garbage at looking, don't be suprised if that's the case )
