Something very weird is going on for sure. I have a 5820k and a 1080 Ti and never see my CPU being taxed that hard. What games are you noticing this on?
Edit: Have you updated to the latest BIOS for your MB?
Got mine today too! I love it so far. Felt a little weird at first coming from DA Elite but my aim is actually a bit better. Low weight, better for hybrid grip, etc.
I love the software too and I love that I can get an announcement when I change profiles or DPI.
