Yes, but I don't have 17 minutes to watch it. Plus I might not see what you're seeing, so explaining where you feel PSSR fails would help me understand the point if I do get chance to watch.
Seems the Pro adds a little magic to PS5 games even if they aren't Pro optimised. Black Myth Wukong shows a 10-15fps increase in demmanding scenes out of the box. I'm guessing this is maybe the extra memory bandwidth coming into play?
