If you have multiple Aura programs they might be fighting over the lighting service. I just did a fresh windows install with only armory crate, rog7.1, & gputweek2 in an effort to fix all my aura issues. So far, all my aura is working prefect! Just checked cpu usage and its sitting at 1% steady with starry night on, then bounces between 0-1% on static color, I got a Ryzen 3900X and on latest winwdows/crate. For reference, I'm controlling 11 aura sync items on my desktop. Gonna be 15 once I redo the room set up.
