If you run live2D, and struggle to run your model, and the game at the same time consider pre-recording your gameplay footage before stream. By pre-recording your gameplay footage you allow your PC to have more free effort to dedicate torwards streaming, and running your model. By pre-recording your gameplay footage before stream you also allow there to be more than afk moments when you feel like going on a tangent. Gameplay can be a conversation piece for you to enjoy with chat. I don't know why everyone thinks gameplay has to be live to be enjoyable. I myself stream live gameplay footage everyday, and only average 0.2 ccv on my own channel. I remember when I was browsing my favorite category on twitch I found a channel once that works like a juke box, but for canned gameplay footage rather than songs from various artists. The idea of the channel was that they hired various talents to perform a game in discord to which they bought the rights to and then incorporated into their channel. Viewers pay, and in return their favorite game and category begins playing on the channel. It was a interesting idea. Didn't have lots of viewers, but it did have viewers. I imagine with a vtuber host to hang out with it could have seen even more success than simply functioning as a radio similar to Pandora radio.
By having pre-recorded gameplay footage you can be on the topic of a game category while also being more free to play with your model, and do mod settings like channel point predictions, and channel point polls. The only down side is all backseat chatting would go to waste, but few vtubers like backseat chatters anyway so I really don't see any downside.
https://youtu.be/IYEQCDt5PYYI would imagine your channel could be sort of like this scene from popular film finding Nemo. You could all gather round, and enjoy watching something together outside of discord for once. Think about it. Who would bother to DMCA you for watching your own gameplay VODs? Not everyone is so shallow that they will only hang out with a vtuber if the vtuber watches their favorite old films in discord. Some chatters are there to experience something with you that is unique to your channel, and goes beyond what can be found at a discord, or movie theater.
I understand it's very tempting to do what everyone else is doing, but I'm going to be honest with you most only copy what works for the top 1% of twitch without ever considering that those influencers are already set up, and that their methods don't have to influence them because their methods might not work for the people still climbing up, and finding their own way on what does, and does not work for their own channel.
On another note if you're an artist you might want to consider doing a slide show of your art in a art gallery format during your brb screen. There's a lot of artist vtubers who I'm surprised to hear news of that they are an artist because they rarely show their own works during their normal streaming grind. I understand it's very tempting to show fan art, but it doesn't really advertise, or inform new viewers that you yourself might be a artist with works worth looking at, and maybe prints worth buying, or slapping on a coffee mug if you ever get into merch stuff.
