Sounds gross, I’m not gonna touch that stuff

The PS5 version of Cold War is same size as on PS4?

ID: hc7fw58

Yeah, which is fucking massive. Easily twice as big as it needs to be.

Weird that they are talking about kraken and don’t know who developed it:

“What is unclear is whether Kraken was designed by Sony internally or by Marvell for Sony.”

A quick Google would have showed them it’s neither Sony or Marvell but RADtools who developed the compression algorithm (RADtools is now part of EPIC.)

ID: hc6n38t

Aren’t they behind Bink? I remember Bink beings used in pretty much everything with FMV.

I seem to remember them and Factor5 being wizards with compression.

ID: hc786wv

Yeah RAD has been around forever. If you're old enough to remember Miles Drivers, same company 🙂

ID: hc87nid

They had a funny business model, the encoder was free, but you had to pay for the decoder. I had a 10-20 email correspondence with them when they asked me to remove the ability from my media player to play their format. All I did was using their dll (which I did not bundle), but they still insisted.

ID: hc6uha8

Kraken was made by RAD but the hardware version may be designed by Sony

ID: hc7cyk3

Thats exactly what it is.

Oodle Kraken is software and can work on any CPU, but it sings when hardware accelerated, which it does on PS5 with a chip that was designed by Sony with collaboration by RAD. Oodle texture also benefits from being accelerated by the custom I/O.

ID: hc775ec

The answer is probably not as simple as a quick google...

ID: hc7y3ri

It literally is. You might even get the cerny video where he explained all of this a year ago...

I don't think the author knows anything about RAD Game Tools.

This was explained by Cerny at the deep dive

ID: hc6wmky

In excruciating detail 🙂

ID: hc7kbnn

Well yeah, it was a deep dive, not a shallow splash in the kiddie pool.

CoD: Don't worry, we'll still find a way to take up half the drive space.

ID: hc6obd7

Unfortunately it’s not just COD. A bunch of games these days are ~100GB.

ID: hc6pxuv

In case you're not aware, Cold war is over 200GB

ID: hc6uedm

While true, CoD are easily the worst offenders - especially when you factor in how successful the company is and how many resources are at their disposal. Their absolute refusal to compress their files was obnoxious in the previous gen, but is now borderline inexcusable considering the PS5's limited stock storage space.

ID: hc72dw1

Currently downloading Final Fantasy from the PS+ Collection. Whopping 100GB. Glad I got a hard drive for my PS4 games because otherwise I would probably have canceled the download

Kraken was defo not developed by Sony.

Yeah this author is a moron.

No SSD controller or Compression Algorithm can defeat the might and file size that is Call of Duty. lmao.

10 : Anonymous2021/09/09 19:02 ID: hc7rf4o

The custom SSD controller is NOT responsible for the decompression, that would mean that third-party SSD's wouldn't be able to use the it, which is obviously not the case. The decompression blocks are on the SOC, the SSD controller is on a separate chip. This is a really bad article

11 : Anonymous2021/09/09 19:31 ID: hc7vpll

and the update still isn't out for NVME use.

I just love the technological advancement Sony shows with the ps5 ❤️❤️❤️

Now if only it also worked on ps4 files

14 : Anonymous2021/09/09 13:58 ID: hc6k37i

Is it already in place?

Because FF7 is still a massive file, although it is somehow smaller than the Ps4 version whereas I would have expected bigger due to more details and such.

ID: hc6prbu

Kraken doesn't automatically make games smaller. They have to be developed with that in mind.

Extra difficult for cross-platform games, as other platforms are pretty similar otherwise, and keeping multiple versions of games adds more cost to development.

And to answer your question: it's part of the PS5 core since the beginning, which is why not any SSD is accepted into the PS5.

ID: hc7cu98

I mean there is a lot of things that make games smaller on ps5 but the biggest one is asset duplication is not needed now.

Let's pretend you have a shooter, to play the sound of the pistol you need to load up that sound from the hdd.

So because the hdd is so slow you tell the game to load the sound file any time the pistol is selected just so it's ready.

But wait. What if the enemy has the pistol? Well you can't not have the sound so you copy the pistol sound file and paste it anywhere it would be used.

You can have that same sound file 10 times in your game

With an ssd it doesn't matter where the file is. It can load it at the same you don't need to copy it 100 times.

It's worth mentioning though this is solved with virtually any ssd. The xsx fixes this issue too. Sonys ssd is just faster but reality is there has been very little difference in terms of any storage benefits shown so far with ps5 over xsx.

The major benefits have been ssd over hdd though. The upgrade is huge and cannot be over stated at this point.

ID: hc7d7i5

Several PS5 games are smaller than their PS4 counterparts. Not as much as 60% though

ID: hc6pyxw

It’s smaller because even thought the files are more detailed there isn’t duplicates like the PS4 version. PS4 version needs many copies of the same file in different spots on the hard drive to lower loading times so the hard drive Doesent have to spend more time “finding” it on the disc where as sad is instant. So instead of 5 copies of a low res file we have 1 copy of a high res one. Make sense?

ID: hc6qty9

Yep makes perfect sense, thank you.

Been pkayinng Ghost, the loading is pretty much instant on the PS5 compared to the PS4, I assume is the speed that let PS5 put less file in SSD and more ran directly off the Disc?

BUT for FF7, I am using a PS4 version with digital upgrade to PS5, so the info they look for on the Disc shouldn’t be there? As my Disc is PS4 version so “the high res one” doesn’t exist on it?

But yet the PS5 upgrade file is still lower than the PS4 file. IIRC PS4 was close to 100 GB but PS5 is only 80 GB or so.

More like deleting 4 games instead of 5 lol

Games don't share assets with each other. You can fit more games that are optimised, but not infinite amount.

Do we have any major comparison (of a lot of games) of game sizes between Kraken based compression and non-Kraken based compression in games. Say like between PS5 and XSX?

ID: hc6sdl4

Yes, Google is your friend.

20 : Anonymous2021/09/09 18:35 ID: hc7nhc4

I'm happy they compressed the file sizes but i wish they could have compressed the actual console. Damn thing is behind my TV because it doesn't conveniently fit anywhere without me buying new furniture

21 : Anonymous2021/09/09 21:20 ID: hc8bswb

Of course it's a customer controller? Where else have you seen a 12 channel SSD?

This does not mean it's doing anything super significant beyond that. Some of the more 'unique' aspect of the I/O happen in the APU. The SSD itself seems fairly straightforward, aside from of course a 12 channel SSD being pretty beefy.

22 : Anonymous2021/09/09 16:46 ID: hc77o8i

Well why tf are games still huge! The way Sony lied and still releasing cross Gen, 3rd party devs won't do jack for years

23 : Anonymous2021/09/09 17:04 ID: hc7acfu

Why wouldn’t they be huge? It’s not magic, it just takes a large file and makes it smaller in the cases where compression works

Doom eternal for example is smaller on PS5 than on PS4

24 : Anonymous2021/09/09 21:26 ID: hc8cjts

File sizes will always go up in time. We're seeing a temporary dip right now with PS5, but as developer ambitions grow, file sizes will creep back up and beyond.

Yeah but is it 2c hotter than regular ones
