Right im going to point it out again to Crosair specifically the email reply that told me to check my expectations, the software is bloated, all the rgb keyboards should have ram and cpu to feed the keyboards microcontroller.
If you really want to lower the icue cpu % to near nothing when say a keyboard is inactive, set the sensor logging period to 9999 sec. change the page and close the GUI.
Now the idle cpu% is around 1% instead of 6% --- WHILE DOING NOTHING
I REPEAT FIX YOUR SOFTWARE PLEASE
