i would post screenshots but i am having trouble figuring out how to attach it here, but ill just describe. on the software effects page, where u can modify the led in the mouse just doesnt work. any option i change does nothing to the mouse led. on the performance page there are 4 sliders with dpi ranging from 250 to 5000. it says current stage:2 and there are buttons u can turn on and off on each of those sliders, but i dont even know which color means its on and which off but ive experimented, and the sliders have changed absolutely nothing.
