STEELSERIES GG SOFTWARE
You can control your prime wireless gaming mouse from the SteelSeries GG software (Engine tab) but before you can do that it will look for available firmware updates.
Once inside the settings tab you'll be able to program all 5 buttons (plus the scroll up/down functions), create macros, change the DPI levels on all 5 modes, adjust the sleep and illumination dim timers (inactivity), enable/disable high-efficiency and smart illumination mode and you can of course adjust angle snapping, acceleration/deceleration and polling rate.
Moving to the illumination tab you can only change the color and effects (3 in total) of the single RGB zone.
