Looks amazing but there are some things here that fire bullshit alert in me:
- frame-rate was atrocious. Sub 30fps for a tech demo. No way real game looking like that would even be 10fps.
- despite claiming that every light is real yellow light coming out of device at the end didn't gave any light
- i don't see how this can fit into VRAM if they are really using raw assets. For those who don't know some assets can be 10-20GBs each let alone scenes which could be terrabytes of data.
Imho demo was not actually on PS5 but on some professional PC with 20-30GB of VRAM.
And for those who want to say "you don't know anyhing" etc. UE4 also was presented with tech demo that was running "real time on next gen consoles" that in the end was cut down in scope and its main feature global illumination was also cut out demo also went back from 60fps to sub 30fps.
original UE4 tech-demo
console version of that tech-demo:
I think is likely due to the deal SONY has with them.
PCIExpress 4.0 is rather new. There are already SSDs with 5GB/s and there should be better ones in following months. Both new consoles aren't using some space tech, just bog standard PCIExpress4.0.
Are you really comparing this to a gameplay demo?
It wasn't gameplay demo because it was techdemo. Techdemo =/= game.
