I did a lot of troubleshooting steps and it seems the interrupts/core 0 high usage begins when I start iCUE and not Corsair Service.

I tried to disable Corsair service, remove iCUE from startup and the issue only begins when I start iCUE manually particularly when it starts detecting stuff.

I also tried to enable full software control for the RAM and interrupts dropped from 80-90% (6-7% total) on core 0 to 20-30% (2-3% total). However, CPU usage of iCUE.exe increased, but this is expected.

One funny thing is that, if I have the high interrupt issue and put my computer to sleep and wake it up, no more issue! This is until reboot though.

I have a Corsair K55 keyboard, Sabre mouse, H100i Pro, 4 Vengeance RGB Pro 8GB DDR4-3000, 1 Commander Pro with 6 LL120 and 1 Lightning Node with 2 Lightstrips.

I don't have Asus Aura or any Asus utilities installed, no benchmark or hardware info tools that could interfere with iCUE.

I will probably stick with 3.18 in the mean time.
