I have a Z370 MSI Pro Gaming Carbon mobo.
When I select the rainbow animation, but I think its cycle waaayy too fast I cannot control it's speed.
Mystic Light has a slider called "Light Speed" but it does not react to any kind of click (L,R & Mid)
Reinstall and/or update any applicable software and drivers.
Failing that, verify that your overall system and associated components meet all necessary or required specifications. Could be some limitation(s) or specific requirements stated in the fine print.....
On the MSI Forums and went to read the recently posted guide of Mystic Light 2. In this guide it says "Currently only gtx 1080ti Lightning (...) supports Light Speed/Brightness and no device supports direction
So, I made a post on MSI asking them to enable speed control for mobo animations.
I am having the same problem plus more. I have uninstalled and reinstalled the mystic app multiple times, but i never have been able to click on anything but the "rainbow" setting. no colors. no speed, absolutely nothing.
