    I'm having the same issue. I have an ASUS ROG Strix Z370-E motherboard with an 8700k and was noticing CPU usage was 20%+ at idle. I ended up narrowing it down to the Lighting Service... Service. After restarting the service, it would go down to a more level, but soon spike back up. Disabling it completely would get my idle loads down to 0-1%. For a completely unrelated reason, I ended up with a fresh install of Windows 10 with the same issue right off the bat. I now have the Lighting Service disabled. Not sure if this matters or not, but I also have G.Skill Trident Z RGB memory and a Cooler Master air cooler with addressable RGB. I haven't done any testing beyond the fresh install and determining what my usage cause was.

    Asus Release Lighting Control 1.07.17 Beta, it's ok with me now. Old version can't OFF RGB 1060 ROG + GSkill Trident Z same time.

    Yeah all the dynamic lighting modes use a significant amount of CPU. On my overclocked 9900K @ 5.1GHz it uses around 6% CPU constantly. It's just enough to prevent my CPU from downclocking and downvolting very far, if at all. I expect some CPU usage given that it needs to communicate with the lights a bunch of times each second, but this seems excessive.
