UPDATED with fiddle: As animations go faster there is increasing error in accuracy

Don, thanks for the reply.

How would I find out if it’s a problem in my code or a bug?

I have seen tween.js and thought of using it but I wanted to fully explore the built in animation system before pulling in another lib. Nowhere in the docs is it clear about the exact use case or limitations of the system, so that’s a def place for improvement either in clarifying intent or clarifying proper usage.

As for “aligning your go() function with the render loop”, do you have a quick example? go() is async so it can await each animation and I don’t want to be updating a mixers clock or rendering like that I think…
