Virtual Sims 4 Streamers?

So I'm just starting out with streaming and want to do it with my new Sims 4 BTS Legacy Challenge. I tried it for two hours last night, apartment customizing and it worked well but it came out a little laggy. My audio was fine but I lost frame rates a but and my Pngtuber wasn't moving well. I'm curious if Sims is just a hard to stream as a virtual.
