Many of my Avatars go from 40,000 to 100,000. Rarely do they go over 100,000 at all. 93,000 is the highest common one I use. I set the render to render all Avatars. By that I mean max complexity set to unlimited. And even when I am around many that are 50,000+ they render fine and I don't get lag. I must have a good PC and Internet connection or maybe Avatar render is overrated and most people should just max it?
