Mouse doesn't feel smooth at all Hey man,
Yeah I have a corsair KATAR with 6000 dpi as well. I use the xbox one base profile. I get choppy mouse movements but I think that is just how xbox is programmed. I mean the people at iogear do their best to make it like PC but it will never be exact. If I was you the best thing to do is to lower aim down sight sensitivity because that helps with chopiness I know for a fact. Apart from that, Happy Gaming.
:p
