lol no that isn't what's going on here. Not console warring either. I own both consoles. The developer himself tells DF he didn't port the PS4 game to PS5, that he went further and rewrote the engine for the PS5's low level APIs, something people are conveniently trying to gloss over and ignore. Saying the PS5's memory setup and clock speed helped isn't the same as saying the Series X can't achieve 8K because of those differences. Series X at launch didn't benefit from the kind of engine rewrite by the sounds of what the developer said. Seems Series X is running a port of the Xbox One X game that's been updated for Series X, rather than a whole sale engine rewritten specific to the series x's strengths.
If I'm wrong, that's fine. There's nothing wrong with PS5 being better at something. We do know the PS5 should have a pixel fillrate advantage, for what's that's worth, but my understanding has always been that few games ever truly bump against those limits and are sooner to be limited by other inefficiencies in an engine. Maybe this just one such case with this particular game. I'm fine with that. I was just going off of the way things were written and explained, as well as the timing of the releases all things considered. Even shadows are done differently in the PS5 version.
As we are in the realm of suppositions:
What if he rewrote the engine for the low level PS5 API because he could, but couldn't go any lower on Xbox?
