Dude...if you really want go down to this route, I'll give what you want. At the start of the next generation, before anyone knew a shit about the state of development on both console, Dusk Golem rumoured RE8 rans perfectly at 4k 60 FPS on series X when it struggled on ps5 at 1080p. Now everyone knows the tools were quite behind on series X the first months, but for bizzarre reason, Capcom, a japanese company, notorious to give his best on Xbox platform, not had any issue on series X; not only! it runs flawless a game at the quadruple of the resolution of the ps5, where it was more problematic. Something not sounds weird to you?
I'm saying it's impossible a game cans run worse on ps5 at the early stage or it can't run better on series X? Who knows, maybe, everything could be, but it's not that point. The point is to not use a nonsense rumours of Dusk Golem when it was debunked by him quite fast, thanks to the many developers who putted him in a corner, asking more evidence about it.
