EPIC forced to "Rewrite" parts of Unreal Engine 5 demo to "Keep up" with PS5's SSD

Sony haven’t been patting Epic’s back. They haven’t made a single comment on it. If they had it would’ve been all over here.

Epic are trying to sell their engine to cross play/cross gen studios. They show it first on the best hardware they can - that happened to be PS5 rather than PC this time - to get studios excited for the tech and make sales.

Sony aren’t involved in that. It’s irrelevant to them what engine 3rd parties choose - they’ll ensure all major engines are supported on their hardware and I’m sure they’re supporting the other major engine developers to the same extent as epic.
Unreal Engine tech demos have been releasing on Playstation consoles for ages... It has nothing to do with "showing it first on the best hardware they can".

Thanks that was a useful link. I found that fascinating that that article says external storage would not support PS5 games. Mind blown at that statement, that can't be true. From that page:

"Using an external hard drive

As with the PS4, you can plug in an external hard drive to download games. This won't be nearly as fast as the PS5's internal SSD solution (and though not explicitly said, likely won't support PS5 games as a result) it's perfect for storing your existing PS4 library (which the PS5 backwards compatible with) to free up that fast internal SSD."
I think that's referring to running PS5 games from an USB 3.0 External drive. They're designed to utilize the high ssd throughput. I don't see why you couldn't store a PS5 on the drive? You should be able to store the games your not playing then move them into the ssd storage when you do. I thought Microsoft had a system with the XOne that determined what games hadn't been accessed in awhile then deleted them so you never had to manage storage. It'd be cool if PS could transfer games to an external like that.

I would not mind uninstalling all my games to load one game that weighs 500 gb or 600 gb. Just to behold an awesome game. It would be a pain but i can live. I will pay close attention when external SSD get certified by Sony.

I'm curious of this as well. USB 3.0 "Theoretical" speed should be around (5 Gbit/s) This is close to the very max, and I don't know is Sony has created the architecture to transfer USB 3.0 speeds to the very max?
So a 600 GB game is around 4800 gbits
4800/5=960
960/60=16
So i believe theoretically you can transfer a 600GB game to and from an ssd within 16 minutes (potentially)

what would be awesome is that when the ps5 detects a 600GB game to be installed it automagically choose N number of games to free that many space, and when you are done with that game the system asks you if you want to restore those games and it would download them in the back and installing them. And it would ask you to insert the game disc when you want to play them again.

I actually hadn't noticed that xD. Welp, seems like tradition for Epic and Sony, then, more than anything else.

HZD1 is 46 GB, even if we get a 5 fold increase in asset details (500 %) that is still less that 200 GB (to Blu ray hi def disks). Cant see anyting being bigger than that.

Although last COD game takes about 214 GB, but those are almost like 3 games in one so who knows and COD install sizes are crazy vs everyone else so ...

I think if there ever is a 600 GB game next gen you get a star.

Yea, I realized that after posting. I was meaning if you had 600GB of games on the ssd that wanted to get transferred over. Can you imagine a 600GB game! 16K graphics streamed directly!

You are contradicting yourself. For multiplatform games, devs won't build their games around a single SSD or I/O. They just use the PC SSD as a baseline and call it a day, so that would mean better loading time for PS5, but not better textures. Devs won't create new textures just for a single platform.

Anyway, we will see as soon as the multiplatform games arrive.



yes and thats when devs will use PC SSD as the lowest common denominator and call it a day. No different gameplay, or textures on PS5/XSX. Only better loading times.
Usually when building models and textures you start high and take out Complexity to make it work, on “lower end machines”.. so wouldn’t they already have the assets that could be streamed in with out having to do any extra work?

FF7:Remake is a single game at about 100gb. With your logic, if we were to get a 4x increase in detail it could easily be over 400gb. combined that with if they were to get more ambitious with the scale of the game.

Next-gen games can't be counted like this.

It is logical though, Spiderman example below also saves GB. And is it compressed with Kraken on the HD - doubt it lol ?

That game also shipped on a 50 GB disk did it not ? Did it decompress on the drive to 100 GB or was 50GB downloaded ? I loaded it from disk, cant recall a huge 50 GB update ?

So with Kraken and HD decomress + no dupes, I bet 40 GB would stay within 200 GB and 5 x IQ. Done.

Unreal Engine tech demos have been releasing on Playstation consoles for ages... It has nothing to do with "showing it first on the best hardware they can".

UE tech demos weren’t first deployed to PS - that is the point.

UE demos have traditionally been shown on PC first before other platforms. This time Epic chose PS5 to debut.

For obvious reasons - it’s the only platform that shows their tech in the best light. For all we know it’s the only platform they could stably demo UE5 at the the time. .

You didn't watch the PS3 link. Got it.
 
Oh look, Tim Sweeney saying a bunch of bullshit for Unreal Engine at a Sony presser.



"All the effects you've seen in previous generation movies are now being done in real-time with this generation"

"It's the real difference between what's been seen in video games before where you have 8-bit graphics versus what you see in film"

"This was so fast because we have a lot of experience with PC development, and all of that knowledge was immediately applicable to PlayStation 3. It has a very nice development pipeline, OpenGL based, CG shading language based, and all standard based and very easy to write for."

SAID NO ONE EVER

Why does this all sound so familiar...

Although Sony hasn't release details, upgrading the system's ssd (A form of NVMe PCIe 4.0) is going to be costly!
Minimum is looking around $400 usd for 2TB. Is that worth almost a 1K usd console, or will you manage the 825 for as long as you can?
https://www.newegg.com/p/pl?d=nvme+pcie+4.0+2TB

8 TB hard drive back will do nicely. I can live with having 4 or 5 games ready to play, rest i can swap around easy enough.

XSX and ps5 will both be expensive to add SSD space.
 
People still convincing themselves ssd is there savior lul



With there track history. They will come up with a lot of in game engine bullshit all rendered on high end PC's that feature a steep downgrade after it.

Console gamers are easily fooled.

You are totally right, i am already tired of arguing with them, mainly the sony fanboys.
