News Drama Game File Sizes May Skyrocket with Unreal Engine 5’s Nanite, Says Developer


Apr 25, 2013
No oodle texture is RDO compress to native BCn before it goes on disk, for ANY console or PC.

Oddle is from Rad, its similar to BcPack and is like a JPEG to image before you make it native format (BC1-7) and store it on SSD.

The decompress is just Kraken (ps5) or Zlib (XSX) into memory, not much difference but you can look it up if you wish.

So both consoles are doing same thing, RDO compress to BCn (oodle or BcPack) and then small compress onto disk (ps5 Kraken or XSX zlib)....

The textures in BCn format are not comprerssed much by kraken or zlib, so you have to have a lossy change of the raw file, think Tiff to JPEG for simpicity (but more compelx with Lamda and RDO so more like Mp4 in a way).

This is one usage of it and not the one vastly reducing texture size.
in this case the "super compressed texture" take gpu ressources to decode (and in VXA case it is said decode BCpack is part of the dedicated hardware)

It is inevitable. Even with a good compression, any AAA game with 4K assets will easily surpass the 100GB threshold.

Wait...weren't people in other threads saying how game sizes should actually go down because assets no longer need to be duplicated or something like that?

Because if the standard next gen will be 200gb+ the storage on both new consoles will be laughably bad, and probably expensive as hell to expand.
So the some PS4/Xbox game is going to be smaller because of not duplicating and because games are going to be compressed on disk. But a developer can add as much data as they want. There's no limit to that. They might try to build bigger games and so they use up more space. They might want to try and be overly detailed and eat up space because it's practical to do it now.

It's expensive to expand. But you don't need to do that. You can reduce the friction with a external harddrive/SSD or just deal with focusing on 3 big games at a time or N big games and M smaller games.

Like red dead 2 and ffviir?

I haven't played either of those games.
And honestly, I don't mind bigger games. I expected them. Higher quality assets/textures, larger worlds etc. all need space to be stored. A new generation isn't just about having more power and devs go crazy with it, more power also can be used to brute force your way to not have to optimize a game as good as it could be and still be able to run. I mean I wonder what would happen if all games would be optimized like for example factorio!

Ps3 games already were up to 50gb in size. Many, many duplicates because of the disc's.
Right. Well I meant 360 games. They got those games to fit on a dvd9 and most of those third party games looked and performed better on 360. PS3 had blu ray. So devs didn't bother with much compression because they didn't need to. But it's quickly becoming insane. 200gb for a game? That's crazy and so unnecessary.

Well duh.

You can't want native 4K, raytracing, 60fps, hi-res textures and great visuals, little to no loading times, bigger game worlds, better sound quality, overall better visual fidelity.

While also complaining about the increase in the size of games. Come on people.

The other viable alternative is cloud gaming, but then some people take issue with that as well.

No assets duplication because of instant random access and no need for Lightmaps due to better GPU capabilities and power says otherwise to me, I think that makes sense to be honest, at the very least it should stay the same or not raise too much.

Yeah, I don't claim to know a lot about this stuff, but aren't higher-quality assets going to weigh in heavier than they do now? So even with no duplication, if everything takes more space, then maybe we'd see the same sizes as now for much higher quality, with some cases of games getting bigger? I'm just curious.
