No generative AI was used during the production of this video (enjoy bad photoshops). The idea behind this video originated right after my debut, when I realized that even with 16 GB of VRAM in certain games I am getting close to utilizing my entire graphics card. I already knew that texture resolution was massive. I didn't however know how much of it is a fault my artist, how much of it is a concept of an avatar and how much of it is the rigger - I don't want to point fingers. Live2D being what it is - it can't be changed - it's closed source and inefficient. But that doesn't mean I can't optimize VTube Studio a bit. And while it's fair to assume most Vtuber will likely end up with models being below of VRAM and it might not be too big of a problem for most, while gathering references I have seen quite a few being bigger than that.
