I'm gonna add:

POLY COUNT DOES MATTER.

The higher the count, the longer it takes to render out the video.

And, 4000x4000 texture sizes are a big pain in the rear for animators unless they have a Star Trek computer to render them out on it can take days, weeks & months to do a few clips of animation in one sitting.

I've just about given up on any figure that is set on high, including the textures.
