I already supplied the link, different demo but same engine. PC running the PS5 demo is like saying the Switch runs Witcher 3. I’m not contesting it doesn’t.
There's no link to say otherwise or any reason to think it would be running lower size texture or assets. The guy clarified any difference in the demo. Which would only be that PC is running the same exact ps5 demo, as well as clarifying that Tim Sweeney need for a super fast SSD was smoke and mirrors. This guy is running the ps5 demo in full quality on his HOME PC.

Within the first 2 minutes you have a flat out statement that there is a "misconception" about this demo and that it runs fine in engine, in the editor on a PC. These are the actual Devs saying this. The Demo would run on a PC, it would run on an Xbox, it would run on a PS5. It is not using the special Cerny sauce. Tim got paid and took us all for a ride.

This is precisely the point people are trying to make here..."EDITOR". Hey is not talking about the I/O stuff since that's not part of this demo and wouldn't be the same on PC, Xbox and PS5.

You are focused on the word "misconception" but not what he actually means and what the difference is between the PS5 demo and an editor demonstration.

VFXVeteran VFXVeteran This whole discussion is that people claim that this is "running" the same as the PS5 demo. Well, it's not RUNNING anything with all bells and whistles enabled since in editor you create, build, move all assets.

Like i said before, run the Valley demo and you can clearly see a difference in performance between editor mode and gameplay. Also they are not showing any of the I/O tech around here in this demo, because it was all in editor.

you have the literal developers of the engine coming out to get ahead of the misconceptions and bullshit that has been spreading and we have people wanting them to do an exact direct comment on every single little thing. It's madness man, Madness i tell thee! haha

You can't do anything but laugh.

To even think a PS5 would run this better than a PC with a 16 core 32 thread CPU, 128GB ram or more, the fastest NVMEs available and 3090's or 6900 XTs is absolute effing insanity...but some still want to believe!!!
 
Sony payed to confine the demo on PS5 seem otherwise we would have all the data possible and imaginable. but after these statements do you still have doubts? the ssd and the i / o of the ps5 you guys have just overhyped
For this reason the lie of Sweeney on twitter
Still no facts lol I said it before untill we see a 1:1 version of the same demo running nobody will believe and it's all speculation.

Gotta keep the dream alive for these guys. If Epic can't shut down the debbie downers, no one can. Might as well take a deep breath, and BELIEVE.



not gonna happen

The link I provided states the new demo was running with 4K textures on PC. It’s the same engine. He never uses the words ‘full quality’, that’s your addition.

Imagine having a engineer make a video to explain misconceptions that people have only for the people to still not believe it and continue to claim different.

What a time to be alive in.

Summary. That enginner is unable to show that PS5 demo running in its full glory on much potent PC .. even one year later.

We all agree. Good.

Not this demo, the more recent demo.
It’s pulling in the same textures from the old demo but displaying them at 4K

One matters, the other doesn't. Running in editor mode is more taxing on the system due to all of the overhead involved in running the actual UE5 editor. The FX, the particle bugs, the climbing and jumping and the cinematic fly scene in the end are inconsequential to running the demo in compiled out mode (i.e. they take very little cost compared to Nanite/Lumen). The PC will run that demo faster and at a higher resolution than the PS5. Period. There is no discussion. You don't need to see the demo run in compiled mode. It's already in it's worst running form - i.e. the editor.

Like i said before, run the Valley demo and you can clearly see a difference in performance between editor mode and gameplay.
Read my thread on my own benchmarks. It's running at native 4k/ 50s- > 60FPS in compiled mode. Where the editor runs less than that and requires more system resources than the packaged exe.

What fsr vs native comparisons show us is that with this level of detail rendering resolution already cause loss of a good amount of them.
This is an important thing people doesn't seem to notice.
rendering resolution will matter to see all thoses details.

It runs the ENTIRE demo, without any need to stream in textures, as everything is loaded into ram, at better performance. What more do you need to see? If they ran the demo the same way as ps5, instead of running the editor on top, the same results would maintain. PC performance>ps5. There's no mystery or secret mirrors going on here.

Lumen in the land of nanite is what he completely loaded into RAM, so that specific demo will run better on a PC.
Valley of the ancient demo specifically shows how Unreal Engine 5 is super efficient at streaming since the data isnt that large a PCIE4 SSD isnt actually needed to load in and out data.
Valley of the Ancient was used to show off how you could use Unreal Engine to make open world games that can stream in millions of polygons.
Test the demo yourself and see.

P.S We already have SSDs that catchup(read as trump) the PS5 SSD.

  • PS5 SSD IO — 5,500MB/s reads, 5,500MB/s writes
  • PNY XLR8 CS3140 —7,500MB/s reads, 6,850MB/s writes
  • Adata XPG Gammix S70 —7,400MB/s reads, 6,400MB/s writes
  • Mushkin Gamma — 7,175MB/s reads, 6,800MB/s writes
  • Sabrent Rocket 4 Plus — 7,100MB/s reads, 6000MB/s writes
  • Samsung 980 Pro — 7,000MB/s reads, 5,000MB/s writes
  • WD SN850 Black — 7,000MB/s reads, 5,300MB/s writes

And before you come at me with the whole "compressed speed" thats not relevant right now.

No PC today can actually get anywhere close to those speeds through the entire I/O pipeline from storage to GPU memory and caches. That's what Sony has made sure the PS5 CAN do through a bunch of custom silicon.

As long as everything you need can be loaded into RAM, sure, no problem (except for a longer initial load), but what about when you're not just running a very limited demo? How is it gonna work once you have a full game at this quality level?

DonJuanSchlong DonJuanSchlong Why would you respond with a "crying with laughter" emoji? I'm stating basic facts. PC is, at this moment, far behind in terms of full I/O pipeline speed. But ahead in terms of potential GPU power (if you can get your hands on one) and RAM size, obviously.

🤣 Yeah it's bizarre. You have new Epic provided demo that runs at 30 fps 1080p on those new consoels and at 60 fps 2560x1440 or even higher on PC and yet some still claim PC can't run it as well as consoles. :messenger_dizzy:

What happens when Direct Storage releases? You already have PC's running just over 3x over ps5 on UE5. :messenger_face_screaming:

once more time ..

PS5 SSD IOP: data from SSD direct to VRAM .. shocking !!
PC SSD IOP: data from SSD to main RAM and then to VRAM .. uff .. it's a long way to tipperary it's a long to go ..

PS5 SSD IOP: data depacked by HW dekompressors - Kraken, Oodle format .. neglible or zero CPU/GPU usage.
PC SSD IOP: fuck CPU or GPU and fuck it HARD

.. and I can continue with highly custom PS5 SSD low level access, priority lines, manual control etc. etc.

Since that Unreal demo came out, the fanboys have been absolutely insufferable for weeks even though it was painfully obvious that much of it was just marketing talk.

Now that much of that PR hype has been dispelled, none of the usual suspects are to be seen.

Since running in editor mode and fly over the area compared to the gameplay was less taxing then running the Valley gameplay with controls, physics enabled, animation, sound, etc etc etc.

You can also see that video i dropped where you can clearly see a difference in performance when compiled it. Also i did run it myself so i don't know and i can easily make video so you can see the performance hit when gameplay starts.

Also the Valley demo is not larger then the PS5 demo. VFXVeteran VFXVeteran i respect you but your also missing the point here what others are trying to make. It's NOT running the compiled demo, but they use EDITOR MODE to fly over the area. If this demo we've seen today was so taxing AND the SAME?

Why do we not see any VFX...in this scene for instance?

PS5 realtime

PC editor mode

See it's not the same, nothing is enabled. So it's not "running" with all mechanics enabled, it's "RUNNING IN EDITOR".

Did you wanted to say something? New demo runs at 30 fps 1080p on PS5 and you have fellers running at 2560 x 1440 60+ fps on PC already even without Direct Storage. Lookie at this trhead here > https://www.neogaf.com/threads/unreal-engine-5-running-as-an-exe.1607957/page-2

Not gonna lie, but I'm waiting for geordiemp geordiemp to school us on cache scrubbers, and why this demo was actually running on ps5 hardware, and not PC.

This guy is running the ps5 demo. The same file that ps5 used last year, with the exception of adding in 2 bikes to the demo. So PC ran at better performance, better framerates, more assets, more textures, etc, than ps5, etc.
I don’t think we’re going to agree mate. :messenger_squinting_tongue:

The way I see it:
-The PS5 demo was old and ran 8K textures;
-The new UE5 (PC) demo ran 4K textures, there’s no logical reason why Epic would change the textures to a smaller size and as we know it scales down to fit;
-The demo in the OP doesn’t state it matches or beats PS5, only that it runs

But agree to disagree.
 
OK guys. At this point, I would ask the mods to shut you up. It's THAT ridiculous.

Not only did you ignore the author of the technique about this demo and explanations about the hardware and it's limits, you are continuously trying to push an agenda even AFTER the author of the technique tells you otherwise. First it was a demo only made for PS5 because of it's sole piece of SSD->VRAM pipeline and no other hardware could render the demo. Then when the recent demo comes out, it's "well that demo was scaled down to work on PC/XSX". Now it's "well the author doesn't play the entire compiled out demo with FX in the video so he hasn't proven anything".

To the non-Sony warriors, it's not worth arguing page after page after page with these guys' PS5 superiority train. They will spin anything and everything to not admit they were being too fanboyish and needed to come back to earth in 2021.

A straw man (sometimes written as strawman) is a form of argument and an informal fallacy of having the impression of refuting an argument, whereas the real subject of the argument was not addressed or refuted, but instead replaced with a false one.[1] One who engages in this fallacy is said to be "attacking a straw man".

That's out of the way. How does a PC without NVIO and DS run a large UE5 game which needs fast streaming better than next gen consoles?

OK. Let's just make this very simple without me explaining pages and pages.

Physics being turned on offers 0 benefit to the PS5 over the PC. Like none. If people have a CPU like I have (AMD Ryzen 3950X), it will run that simulation code significantly faster. Period.

Animation rigs, are also a CPU-limited scenario.

Sound is also CPU-limited.

The entire frame budget of that demo is completely dependent on Lumen and Nanite (i.e. shading, lighting, geometry throughput).

If you think that the PS5 can outperform a PC in *any* metric. You continue to do so. But don't argue for the sake of arguing.

Where are the downgraded assets or textures again? The guy specifically stated they are running the ps5 demo, and added 2 bikes to the demo.

It's ok if you don't believe me. Water under the bridge, never under my eyes.

But why don't you believe Epic? Why do you believe ps5 had 8k textures, if you don't believe Epic in the first place? Why do you only selectively believe one thing, but not another from the same source? I don't get this whole fanboyism thing?

It was stated as being 8K textures here.
He says that each asset has 8K texture for base colour, another 8K texture for metalness/roughness and a final 8K texture for the normal map.

Again, saying it’s running the PS5 demo doesn’t mean it’s running at the same quality.
Two different things.

Guys, seriously, hold it together. Keep your composure. It'll be ok. All of this info or proof you need to see, is in the demo. Watch the video if you haven't. And if you have, actually try and retain what was said.



There's no need to be upset

Ad hominem (Latin for 'to the person'), short for argumentum ad hominem, refers to several types of arguments, some but not all of which are fallacious. Typically this term refers to a rhetorical strategy where the speaker attacks the character, motive, or some other attribute of the person making an argument rather than attacking the substance of the argument itself.

If you think that the PS5 can outperform a PC in *any* metric. You continue to do so. But don't argue for the sake of arguing.

And is not a direct comparison to the PS5 demo as we have not seen this demo on PC run in compiled mode from start to finish.

Simply put:

editor mode:
- Everything related to gameplay is disabled, so you have much better performance to build your scene.

compiled mode:
- Every game mechanism runs, so you can see how well it runs, more taxing because this uses every aspect of your hardware. If editor mode was more taxing, you're causing developers headaches.

I'm not talking about benefits for the PS5. That's not the point we're trying to make. The point is that this demo was all in editor.

Another great example, look at Teardown...creating in magicvoxel is less taxing then when it's running compiled in the engine. Maybe not completely the same, but yes every game mechanic is enabled when it's equally running:



Edit: Dude serious, nobody is talking about "outperforming", since what we've seen in their video today is a totally different video then before, and only show how it's been build in editor mode....nothing more.

Don't get me wrong, I'd be upset to be proven completely wrong, and have it blow the fuck up in my face. But at the same time, that's why i refrain from making stupid ass assumptions that don't make sense. So I never find myself in your position, because I don't make stupid ass claims that WILL come back to bite me in the ass.

I believe the new demo is more than proof enough, meaning PS5 could run that one with 8K textures too.

But I see it’s getting a bit heated so this’ll be my last post. Good night!
