Yeah, I know all these terms, but I only learned them from working on the PS4 for a long time. Even those quite familiar with graphics might struggle to read this article.

GS = geometry shader, and it's main gimmick is allowing you to generate triangle topology on the GPU. So that's why it should be "obvious" that a GS lane can control more than one output vertex. GS was also a terrible idea, because it's slow.

Hey, geometry shaders can be awesome but they do have limited use. I guess it might fall out of favor if we end up with Nanite taking over.

Them falling out of favor has nothing to do with nanite FYI, and you would not want to use GS for any of the benefits a tech like nanite gives you because it's far too slow. We've all moved to CS for that sort of things if you can't rely on AS/MS
