The full release of UE5 is sure be even more impressive and is likely to receive improvements over the years, good to know that PS5 will have enough headspace to grow with it over the years.

Ask yourself if a demo is using half the PS5 GPU power, why are developers struggling to hit native 4k/60fps then?
I'm really curious as to how Epic is making such claims when everytime they have shown off a UE demo, even back on PS4 it wasn't until the end of the gen that we saw anything close yet they claim its not "as intensive" and Fortnite is exampled. Something genuinely isn't adding up in the numbers but the only reason i think the performance didn't tank as much is Ray Tracing wasn't used.
