Uninstall the software. Seriously. That was my solution. I couldn't get any of the lighting effects to work right when I tried it on my Strix 3090. All of the effects were the same, and none of the effects would ever display more than a single colour at a time. I didn't care for the software at all. It felt clunky, and then when it didn't work I said screw it, uninstalled it, and now I have the default rainbow. It's fine I guess. I really wish though, with all the RGB people cram into everything, that there was good software to go along with it. Having a $2,000 card, with a big lightbar down the side, but no good software to control it kinda stinks.
Corsair in my opinion has the best RGB Solutions in the business right now. ICUE has become a really good app. They update it constantly and have put a lot of effort into it.
3090 is not even supported by asus aura. its a disaster why even have rgb
