I am still having this issue. Cannot remap DPI up or down without the mouse always retaining DPI up and down functions. Cannot even disable them. I tried explaining this in a ticket but Corsair takes over a week to respond to one email.
I have since uninstalled every driver manually, Deleted iCUE and wiped registry of traces. Reinstalled iCUE and mouse. Still the same issue....
Bump bump bump, theres got to be a fix or someone has to do something about this...
