lol Nanite doesn't just mean using Quixel megascans.

Never said it does. My post doesn't even contain the word Nanite. Strawman hard at work :lol:

What does not being listed as an official partner have anything to do with it?

 

[CerebralTiger]

Guess they're more proud about some studios using their megascans than others :hah:

Who needs 30 hrs games with this fidelity when 10mins walk in a straight line is next-gen for some people :lol:

 

[CerebralTiger]

Yes, it'll require a lot more work from the artists to make games look that good. The tech is there to facilitate it, but there is no auto-generate button lol.

Crunch, crunch, crunch

Pffft...Dreams lol

Good thing UE5 is also backwards compat so we will still see games with it on PS4 Pro etc

[MENTION=26]Chandoo[/MENTION] whens the ps5 reveal man!

I can’t wait no more.

@Chandoo whens the ps5 reveal man!

I can’t wait no more.

The current (unconfirmed) rumor is the 4th of June from a reporter who has gotten some Nintendo related scoops correct recently.

Pffft...Dreams lol

Looks good, but it's just a video at the moment and there's no link to download the project. The Dreams demo is playable in real-time.

Frostbite engine designer chimes in with in-depth thoughts on UE5.

What's up with the SSD? Is the PS5 special?

There are two questions here: does the Nanite technology require PS5-tier SSD speeds?, and does this demo require PS5-tier SSD speeds?

The first question is simple: no. As shown above, Nanite is first and foremost a way of storing and rendering geometry. Despite first appearances, this is an especially data-efficient way of storing geometric detail, and should always look more detailed than a normal-map approach at similar file sizes.

For the second question, you should understand how much data this demo had. The demo had “hundreds of billions” of ‘virtual triangles’, so even if after compression they are spending only a couple of bytes per triangle, and some geometry was reused, that's still way in excess of a hundred gigabytes of data, being scanned over in under ten minutes of gameplay. This is so much data that despite the PS5's insane SSD speed, I actually think there was at least one disguised loading screen, most visibly at 7:20-7:40, where the outside is whited out while I assume that portion of the level was loaded in. An XBox Series X's SSD would have taken twice as long to load this, and likely otherwise been slightly less timely with loading in geometric detail.

The only segment that some people claimed is "next-gen" had to disguised behind a 20 secs loading cut scene :hah:

But but but people told me next-gen assets won't be an issue :lol:

 

[CerebralTiger]

Only 30% thermo usage

If a potential PS5 upgrade results in a higher thermo ceiling, we've already got a next-gen engine in Dreams.

That quibble is what paid partnerships buy you Carmack.

 

[CerebralTiger]

Carmack literally said in the very first sentence of his tweet that being able to load data directly into gpu memory from an SSD is a big deal. In his quibble, he merely states that unbuffered IO can result in better read speeds, but then also goes on to acknowledge the gpu driver overhead that Sweeney mentioned.

So if one part of Sweeney's statement may be inaccurate, the rest of the statement is also false and merely the outcome of a paid partnership, despite Carmack agreeing with it. Right lol.
