The Unreal 5 demo is just as astonishing as everyone says. Wild virtualized geometry & realtime global illumination. Left wondering many things but especially: the scene involves 100B triangles! i.e. 100s of GB? How does storage work for a game like this?! youtube.com/watch?v=qC5Kta

this demo was on a ps5 which has custom harddrive paradigm that even current highest end gaming computers can't match right now. It's explained more in the launch keynote here:

Read lots of speculation about this today, a few folks seem to think that they'll have some tech to automatically downsample the raw assets for shipping.

That was how I interpreted what they're saying in the voiceover. The raw assets had billions, and the engine translates it into something less. Note the rainbow overlay mode shows less than 1 triangle per pixel.

NiN describes it well…
I am just a copy of a copy of a copy
Everything I say has come before
Assembled into something into something into something
100B interim triangles sourced from transformed original object that is copied multiple times (1zillion statues!).

Underrated album.

I had the exact same thought. Along with the thought that a 5 minute demo that prob is 150GB isn’t much use on a system that only has 700GB of storage.

Ah, that's very interesting. A completely new axis to do a "fake" demo that would not work in a real game.

A lot of interesting questions about this tech.
Guessing we are seeing hard surface geometry items being baked into “point cloud” oct-tree GPU objects? Where the points hold posn. and surface properties.
Very clever. But means no deformation?
And presumably no transparency
