Recent UE5 demo needs 72GB total RAM to run at 30FPS while the first only used 768MB on PS5

He pushed for a answer to a question that nobody knows.
I took my stab at giving him the answer he wanted.
What you are saying still makes no sense though.. why would they use a 1080p30 demo to show off resolution scaling techniques?

That isn't really an impressive way to do it.. you'd want to push more detail, or push the framerate higher..

It's also not new either as the PS5 demo used reconstruction.

You mean multiple people pulled you up on the ridiculousness and now you are backtracking.
I'll tell you what i think, i think you posted that video because you were salavating over the 35fps on a 3090, without realizing the demo was running at 4k, and not 1080p lol.

Either option is a glorious backfire.

Did you watch the video and look at the performance,well lack of?

LOL to his clueless PCMR commentary during the video as well.

I think it would be very similar but what wouldn't be is the cost of a PS5 vs the PC in that video :pie_roffles:
Thank you. I just clicked on the clip, looked at the PC specs, then did a slight chuckle.

.....why are ppl glossing over the specs of the PC's ppl are using......

But, please continue to be disingenuous as hell. Just lets me know who to not take serious or even reply to.

Nope I am very serious when I see such money spent netting such compromising results with this demo and with CP2077.
It's good entertainment :)

Did you listen to what they said in the video :unsure:

It's one of the new highlights of the engine and noteworthy for all devices.

I found it very impressive 🤷‍♂️

Yes; they mention it 3 minutes into the video.. and we know it was used in the PS5 demo...

You claiming it was the purpose of the video is pretty hilarious; it was one mention in their script... in their tech docs they make it clear to expect 1080p + scaling for games utilizing Nanite + Lumen on next-gen consoles.. this is expectation setting, not purposefully lowering a resolution to show off a feature.

It's used in both XSX and PS5 footage.
I didn't claim it was the purpose of the video LOL
I said it was a highlight because it was.
Reconstruction techniques will be a big thing for gaming as a whole.

It's used in the original PS5 demo from a year ago..

And you are implying it's the reason they lowered the resolution... there is no reason to think that.
 
I'm really curious to see how this tech runs on the XSS. The prevailing wisdom is it just doesn't have enough RAM to run current gen games. Since lower end PCs can run this tech is it really possible that XSS won't be able to run this engine?
 
Misinformation: the thread

Those specs are for running the demo in the editor. The compiled demo uses 4-6gb of RAM and 6-7gb of VRAM.


It also runs just fine on a regular HDD:


So in the end you don't even need a regular SSD to run the demo better over next gen consoles. 🤣

Epic already said the engine will run on Switch, and even XB1 and PS4. I'm sure XSS will be fine.

I/O based engines will be fine on XSS, better than cross-gen engines that are expecting to use large caching pools.

It'll probably struggle with the next-gen lighting though. That's pretty GPU hungry.

So likely fine asset detail wise, w/ much less fancy lighting, would be my guess.

Don't know but what place to show off this new tool no?

It's a tool to increase performance.. this demo is not more performant than their last.

It's possible the PS5 is hitting better framerates than XSX on this demo, but both are locked at 30... the inverse.. is also possible.

Neither are anywhere close to what a 3090 is doing on PC. And Epic has outright stated that getting good framerate on next-gen consoles will likely require 1080p->4k upscaling.

The lead engineer of Epic China just doesn't know the difference between a video and running something natively. Tim Sweeney told us so.

Yap as i said, the jump from hdd to even a sata hdd is YUGE.
It does seems whatever extras there are, will probably get bogged down by limits elsewhere in the system.

It is good to have a wide tolerance or excess, but with how big UE5 will get over the next few years, and how good it has look....we may not feel that excess in real use. 🤷‍♀️
 
Running a less impressive demo is not a victory for the PCMR. Unreal Engine is a multi platform engine and will scale given fidelity adjustments.

Less impressive?

The graphics quality and level of detail are the same in every respect, except the levels and spaces are actually open world now, no longer small spaces or tight corridors. It's also now more interactive.

You think PC won't be using fake resolutions to run UE5 games?
I guarantee any current GPU will.

Who said that?

This convo is based on people running the game 4k native at higher framerates than the video demo 1080p native.

A 3090 would probably hit 60FPS w/ 1080p upscaled. Unless there's some bottleneck not apparent.

Its not running @ a good performance though the fps was all over the place with a $4000+ build.
Yes it was a higher resolution but we don't know how these consoles would fare at 4K.
Like I already stated we will have to lower the resolution on any PC game that uses UE5 to achieve 60fps+ as well.

Agreed. People in here acting like the new demo was more impressive than this demo:



Come on now...

I'm downloading all of this now ... 5800X CPU, 6900 XT GPU, 16GB of system RAM.

Is it obvious how to compile this thing? Has anyone done it?

I'm curious what that will look like as well. Especially if the target for third-party UE5 is 1080p/30 on XSX/PS5. If XSX/PS5 were targeting 1080p/60, the XSS might be safe at 1080p/30 (giving the weaker gpu twice the time per frame) with a few nips and tucks here and there. I guess we'll know when the first UE5 game drops.

Imagine seeing graphics like that and actually giving a FUCK about a pointless 60fps.

You FPS nerds disgust me.

30 all day, fuckers.

If it were entirely up to me, I'd take the smoothness of 60fps and just knock the visuals back a bit. Hopefully we get both modes.

What if the visuals effect gameplay like physics and shit? Wouldn’t it be better to have more complex simulations at the expense of frame rate
 
I've read three pages of comments and have zero fucking clue what you guys are arguing about. The demo was good. Glad it runs on both consoles. Should help speed up development and improve baseline graphics.
