I'm pretty sure reading my post addresses all this.Well it's pretty easy to explain why Infinite looked bad in that lighting condition given the PBR materials and set up.
He wants more technical explanation like what you get from a GDC talk other than "haha SSD go brrr". It's much easier to commentate on what's presented visually than what is behind the scenes, literally.
He thought about it enough to have questions about how ray tracing is being handled....but have no speculation about how the SSD may be used....
......A GDC talk ends all speculation.....
Lets also not pretend he had previous opinions about the SSD's before that clip.
