I'm getting roughly the same thing. Ryzen 3950x with the following devices:
- K70 LUX
- M65 Pro RGB
- Lighting Node Pro (with only lighting channel 1 lit up)
- ASUS Motherboard
Somehow iCue is often using nearly half a core of my CPU. This seems surprisingly high when my colour schemes are pretty basic (motherboard + lighting node based on temperature, mouse random, keyboard lightning effect).
Any advice other than downgrade?
