Vtube Studio is killing my CPU, what can I do?

Hi. I use Suiikas customizable Vtube model. That itself is already eating up a lot of my CPU. Is there an alternative to Vtube studio that doesnt take up so much of my CPU? Im running a Ryzen 5 5600X. I would like to keep that customizable Model, but streaming with the Model and playing Wuthering Waves at the same time via stream is impossible!

Any ideas what I could to to lessen the CPU usage of Vtube studio?

Im sorry if this is dumb, im new to Vtubing.
