Recently put my Deathadder 2013 (400 dpi @ 1000Hz) into the USB 2.0 slots, after using USB 3.0 for the past 3-4 months, and my mouse feels a lot slower in general, in CS:GO. I've checked Razer Synapse, my DPI/Polling Rate doesn't change or anything, nor does anything in Windows Mouse Settings. When plugging back into USB 3.0, it feels like there's some acceleration added, but when I swipe my mouse from far-left to far-right, I do the same degree turn as USB 2.0 in-game. I also used Enotus Mouse Test, thinking USB 3.0's Max Speed would be much higher, but it turns out that USB 2.0 gave me a higher Max Speed than USB 3.0. Everyone I've asked to test this, says their mouse feels no different in USB 2.0 versus USB 3.0, so is this not normal?
