Huge frame loss while using Razer Naga mouse

while using Razer Naga without Virtual Here I have 0% frame loss and lags, but I can't use 12 button thumb grid. When I enable Virtual Here all buttons work but I get up to 40% frame loss (unplayable) when I move the mouse.

I assure you that network isn't the problem. I tried both wired and wireless with same results. Only time I get frame loss is when using Razer Naga over Virtual Here. Tested on Borderlands 2 @ 30 FPS and @ 60 FPS, no difference.

Can you assist me with this issue?
