Make Character.AI avatars load in their full resolution (400px) and quality (100%), and let them be animated when they should be. I also try to manually find sources of characters' images that are recommended to me by CAI, Shorter script in description. Original script by logan.uswp: https://greatest.deepsurf.us/en/scripts/482793-always-hi-res-c-ai-avatars/code
This script absolutely works, and I highly recommend it. 👌👍
