Really? I actually never hit the dpi buttons, maybe grip further inward? But yeah since Xornet doesn't come with software it's plug and play, it also mean you cannot assign functions to buttons. So you're stuck with you have.
Though if you press and hold down both the back and forward buttons (don't let go) then press the dpi up or down, it will change your polling rate from 125, 250, 500, 1000. I've heard rumours that this mouse optimally operate at 250 Hz but I left it at 500 Hz. I check with mouse rate checker it's a tiny free program.
Another thing is remember to go to CM Storm website and download latest firmware, it will reduce lift off distance to really really low which is nice. But keep in mind the lower the lift off distance usually will result in slightly slower max tracking speed. If you do crazy fast swipes then don't use the lower lift off distance firmware.
Enjoy ~
