Yes, the render part of this plugin is not fully optimized. Some further work is needed on figuring out how those "draw-able" part of model works together. As sometimes model come with only one or two textures, there should be some way to just batch them together.
But as our project decided not to use Live2D, I have little time on this plugin. I tried to upgrade it with UE4 and Cubism SDK, but got no chance to have a future study on optimizing. I might be back at some future moment, but it's not planned, I can not promise it.
