I just don't see why they'd be particularly different between the two consoles considering they're essentially the same architecture. The differences between 4Pro and OneX aren't that crazy.Again it has probably more to do with how the PS4 and XB1 version were coded than the speed of the PS5 SSD.
edit: Did they only add higher resolution textures for OneX That would make more sense given the difference in RAM capacity.
hm....
Ah right.... just found the article.That was the original game release for 2013 consoles. CDPR released mid-gen One X and Pro patches but I've not seen a comparison of them. One X got a 60fps performance mode!
