The recent patches, including the performance improvements, have not been patched to consoles yet.
Certification of console versions, which is for Sony and Microsoft to handle, may take up to a week. With previous versions they have been able to push a patch to consoles within a few days. It’s possibly more of a struggle with numerous patches being stacked up (idk if the firmware update slowed it down any)
I do think there might be more unsolved problems with the console version than on PC.
I’m not an expert on this, but I’ll give it a try: consoles have to deal with a lot of weight(s) from the game. Other titles may manage this better in places, although those are not all open worlds. Performance may be worse depending on one component in your device, but is not going to get way better by having just this one better component in it. PCs have had longer to develop themselves. They’re not really better than consoles, but are better capable to handle certain things than consoles are and vice versa.
