Is there a way to get context for this question without having to watch a lengthy video?

@NicolBolas The link should link to the place in the video where the quote is said. You could skip back by a few minutes, but I'm not sure there is much context, other than to make the point that power usage by a GPU is not always intuitive.

Actually, my question was more what is 'dense' and what is 'simple' in this context?

@NicolBolas Ah, right. I think he was talking about a few, large triangles compared to many small triangles. His example for simple geometry was a map screen, which would have a few large triangles with textures.
