I understand this may scale up to high end PCs (and PS5 pro?) better than the original, but does it offer any advantages on basic PS5 when compared to the original and the PS5 patch they released a couple of years ago?

Didn’t realize they were offering a $10 upgrade for PC players who own the complete edition already. The PSN requirements are an annoyance, but not a deal breaker for me since I already have a PlayStation account. Damn that price makes it a lot more interesting for me.
