Hey Guys, i have a big problem with ICUE. I have the newest version and i dont know why, but my LL120 Fans RGB is always lagging. If i close the ICUE completly then the Rainbow Wrap is turning on and its completly smooth. So i think there is a problem with the Software. So What can i do ? I tried to reinstall Windows, of course new ICUE Software but still this problem. Maybe someone can help me.
