Hi folks - I registered to provide an update on the mouse lag problem, which I also experienced in my Z390/9900KS/2070S rig. So... like others around the web have mentioned, you CAN disable C3, and this will likely fix the problem. It certainly did for me. However, losing C-States bugged me a little, so I continued to investigate. Long story short - I think this is not so much an iCue problem exactly, but rather a software conflict between a very specific type of software and Windows and the Intel Management engine. If you're the adventurous type and don't mind making a registry entry, then you might want to try adding this DWORD to the Intel Management Engine hive. It completely fixed my mouse lag, and I was able to reinstate all of my C-States. I even reversed it to confirm that the problem came back, and it did. Here's the entry: in HKLM\SYSTEM\CurrentControlSet\Services\MEIx64\Parameters\, add the DWORD value PG_DISABLED, and set the value to 1. https://forum.corsair.com/forums/album.php?albumid=847&pictureid=2160 EDIT: I believe the "PG" in the registry key stands for "Power Gating", and is a sub function of Intel's Power Management. Somehow, leaving this feature enabled creates a conflict.
