No. That's not cool of you to play the victim to prove a point and accuse a group of people falsely like that. Not cool man. Not cool.

And I'll be bluntly honest with you here, this exact behaviour is precisely why I find *certain Xbox fans pathetic. This inferiority complex, playing the victim, spreading lies and false accusations really puts me off. You don't have to do that to prove a point. I just don't understand why this is prevalent among certain Xbox fans, especially now when they should be happy they have the upper hand in teraflops and have a very capable and nice device in XSX.

It's like no fun allowed for the competition. No wins allowed. It's all us. Nothing allowed for them. No!

So much hate blinds you from celebrating all the technological advances both are bringing nextgen.

(Yes I am fully aware certain fans of PS and Nintendo have their own complexes as well. Certain PS fans may come off as show offs and certain Nintendo fans may come off as manbabies. Though I'm not sure they downplay and hate the competition as much as certain Xbox fans do)

*Certain Xbox fans = trying my best not to use that certain word.

Bottom line, some people get extra defensive or respond this way because they get over enthused. I agree it's not fair to paint whole groups with the same brush. Although, that's a tendency we have as humans...it's kind of what our history has largely been based on and is the reasons we have countries, borders and have split ourselves into "races" when we are verifiably the exact same species. ;)

The last point feels like a biggie. So essentially Developers can develop games until their heart's content and then scale for the previous generation hardware?

Less capable platforms could aim for more realistic approaches like toned down 1080p,2K, 4K assets. The demo just used mind-blowing, uncompressed Hollywood-level 8K assets. The amazing Rebirth trailer by Quixel used 4K assets compressed by 25% at smaller ratio of 2.39:1 semi-4K@24fps. PS5 is more likely to use more of those 4K and some 8K assets and getaway with it with its unprecedented SSD and i/o, less capable platforms may use compressed 4K or 1080p down to 240p assets to avoid stutter and buffer due to slower architecture and overall process.

Why a "like" to that post would make you that/xbox fan?

Tim Sweeney is basically confirming there that UE5 is tailored for the PS5 SSD I/O unit 👇

ZVEd9Lb.jpg


We already knew that Nanite and Lumen tech will be fully supported on Xbox Series X. Pretty sure that XSX will show its own UE5 tech demo soon too :)
.
In other words, of course XSX can run Lumen and Nanite.

BUT...

Nobody said anything about being able to run that demo, pretty sure it was tailored to take advantage of PS5 SSD.

Too bad we have no remote idea what the actual demands of the demo are. For all that we know it only uses a quarter of the PS5s speeds and XSX is overkill too. They say it runs well in Sata SSDs after all. There’s absolutely no evidence to say that the PS5 is having its I/O tapped out, it’s speculation with as little basis as anything else. You can’t just definitively say that XSX will have downgraded textures

Very true and good point. As I've already said in another response it appears from what Epic said that this demo is exclusive to the PS5 so we WON'T be able to see it in comparison on other platforms. We MAY get to find out more and see if like you were saying the PS5 is being stretched to the max with this demo or what the technical details are around how much data is being streamed per second, etc. Time will tell.

They normally release the demos for you to run in UE on your hardware. So I am sure we will get this demo like they have done with the others once UE5 is out, so it will be interesting to see how it scales across different PCs.

Looking at Sweeney discussion again he talks of no Draw Calls. This is interesting and needs to be explored. Is it because the geometry is essentially streamed from ssd directly to ram to be rendered with no cpu intervention?

Certainly sounds like it if Draw Calls are initiated by the CPU. Looking at the engine again, static geometry is discussed, again backing up Stream vs Cpu. Animating geometry would require Draw Calls. Thoughts?

Bingo. This is largely what I think was meant with the 'scaled down' comment. Maybe other platforms can do all the same but not the 8k assets streamed in? Or maybe they can. We'll see as we get more information. That's the problem right now...we're all fumbling around in a dark room looking for the light switch and with only a half burned thru match to light the way! :)

On the Nvidia DGX-2 - "GPU-based machine-learning frequently bottlenecks on storage, not CPU. The M.2 and U.2 interfaces used by the DGX A100 each use 4 PCIe lanes, which means the shift from PCI Express 3.0 to PCI Express 4.0 means doubling the available storage transport bandwidth from 32Gbps to 64Gbps per individual SSD.". Not that I can afford that in 10-years!

Uh... I don't see how anything I said is 'playing the victim'? Would someone saying that others are pretending the PS5 is 5TF, as an exaggeration of people saying 8TF or 9TF or whatever, be considered 'victim playing'? I don't think so. So what are we talking about here? And this is part of the problem. You can't call out this behavior on one side but you can from the other, and that is bollocks. This behavior you're talking about is prevalent among all competition. Sony vs Microsoft, AMD vs nVidia, Intel vs AMD, Forza vs GT, you name it. No one group has one specific behavior, and your specific targeting of so-called "Xbox fans" says a lot. If we were actually trying to understand the technology rather than both sides trying to brag and boast which one has the bigger e-peen, we would be able to get somewhere. And the issue is that someone neutral is dragged into it, and that is EXTREMELY frustrating. The majority of my posts are about understanding what is really happening and what we really know. I call out illogical conclusions, try to explain things, but for some reason that is seen as hating the PS5, or downplaying its SSD, or being an "Xbox fan". I get tired of this nonsense. I get this a lot less from the other side, ironically.
And if you want to see this as playing the victim again, go right ahead. Doesn't change the facts.

Draw calls are key for the traditional rendering method. But so much has changed with Nanite, that we really cannot think of rendering in the same way. Draw calls are indeed done by the CPU. The whole DX12/Vulkan thing was focused on draw calls, where DX11 was basically trash at using the CPU for draw calls, and DX12/Vulkan are much more capable of leveraging the CPU. How Nanite works exactly right now is unclear. We have a lot of info, but some of the details are still unknown, and most likely will remain so for now. That's why developers themselves are baffled. I mean, rendering without draw calls is an immediate wtf.
As for animations, the girl in the demo is apparently still rendered the traditional way. Only the environments are rendered using the Nanite technology.

Bingo. This is largely what I think was meant with the 'scaled down' comment. Maybe other platforms can do all the same but not the 8k assets streamed in? Or maybe they can. We'll see as we get more information. That's the problem right now...we're all fumbling around in a dark room looking for the light switch and with only a half burned thru match to light the way! :)
Except they were specific that Nanite did away with LODs.

Did you see Dictator's post in the NXgamer thread? Absolutely hilarious, here it is:





Even though in the first few minutes of the UE5 reveal where the developer specifically states that all of the polygon detail is made possible due to the SSD streaming polygons in, he's still on here trying to downplay it as though "we don't know how it scales". He even tries to downplay the SSD by saying that there's not as much normal map data and so forth. He even goes on to say specifically that UE5 should scale with GPU power to try and pain the narrative that SSD isn't hugely responsible for this but somehow a 15% difference in GPU power will be an enormous scaling of power.

It's amazing the lengths he's going to downplay Sony's SSD, though completely predictable.
this is so silly. its great that it scales with compute which should be great news for xbox series x, but there is no reason to downplay the ssd after all the comments tim sweeney has made.

But they did say that they were streaming in Zbrush assets that were 8k, didn't they? Might that not mean that on a PS4 they could only stream in HD assets for example? Or on another platform maybe 1440p? I dunno...maybe I'm thinking about this wrong. I thought that was the point they were making about the super fast I/O with the PS5. The ability to stream those assets direct. 8k is obviously overkill for us right now when even native 4k isn't exactly the norm. Anyway, that's the way I thought they were pointing in the demo.

you’re playing the victim because you frame yourself as a poor neutral man getting caught in a console flamewar, when you’re the one stirring the pot. You’re downplaying any official/expert statements praising the ps5, and exaggerate whatever little hate the xsx is getting In this thread.
Just knock it off.

This was running at 1080p@30FPS with ray-traced global illumination, shadows and reflections enabled all at the same time right? REALLY interested to see how PS5 does hardware-accelerated triangle-based ray-tracing. Guess we'll find out June 4th. (Hopefully)

Well, so far, it's been using "software-based" global illumination on the PS5, which is the most critical type of Ray Tracing that's much more visible than reflections which need certain reflective surfaces. So with that lifted with HW RT later on when they implement it that demo should benefit from higher resolution/framerates. Plus, we're not sure if it was utilizing The Tempest 3D Audio engine or it was using only traditional, pre-baked audio behavior. Global illumination, shadows, reflections were all used in video in real time to some extent, not sure if ray-traced audio. All of those taxing types aren't utilizing the built-in HW RT.

Things are unclear... It was stated in a Eurogamer article that one statue uses 24 8K textures. That would amount to 24 x 7680 x 4320 x 32 / (8,000,000,000) = 3.2GB of assets for one statue. If all statues are the same, no duplicate data is necessary. In any case, the full uncompressed statue can be fully streamed in less than a second (0.6 seconds) by the PS5, while the XSX would take 1.3 seconds. As a reference, an HDD at 50 MB/s would take 64 seconds.

How different would the narrative have been the last 2 months if Epic had shown the demo along side Cerny’s presentation at GDC as planned? Sony really needed to demonstrate why traditional metrics won’t define this generation. The PS5 technical dive along with the demo would have sent a clear message. I think Sony planned it right, but Covid derailed the messaging.

I was on the poor messaging bandwagon, but if things had went as planned we would have been drooling for the last 2 months in anticipation of the June event. I’m going to give them a pass on the lack of information, I think the plan was in place.

Path tracing does it all. From GI to Shadows to Reflections and Ambient Occlusion. That's why it's way more taxing and computationally expensive than bog standard Raytracing.

Aaah...I see what you mean. Yeah, we definitely need more info...and more demos, dammit! I want to be SICK of seeing next gen game play demos and graphic demos within the next 90 days. Nay, I DEMAND to be made sick of it! :)

If the rumor about an October launch is true, perhaps

Boy do I WISH the pre-orders would go live then! And and October release???? If it's October, I'm gonna feel some release myself with the news, if you know what I mean! :)

I've always thought it was silly honestly, to have these boxes up for sale only at Thanksgiving time or maybe a few days before or after. They should have these things out with PLENTY of time for people to buy them for the holidays. Buy them and also try to track them down when they're out of stock before the holidays. I've never understood why Sony and MS haven't planned for and done that. That being said, their marketing and sales data MUST be telling them that later in the year is more optimal...I assume?

Anyway, yes, I hope the pre-orders are available June 4th and then an October release date for the hardware would be just FANTASTIC.

I think so, not sure. You have assets from Hollywood-level, uncompressed 8K assets down to 240p. Nintendo Switch could find something in between, I believe.

Indeed, man. But what we really need to focus on is the final result, and I'll be more than happy with that result shown in the demo with more things going around and gameplay.

His track record as of late has been good and the June 4 date is the date I have been told as well.

Plus I think I have said it here already but I agree with him it will be a full showcase for the PS5.

Late nite guesses and all.
That should include a console reveal right? Judging by the controller design and rumours the PS5 design should be something which will look ridiculously amazing and cool (pun intended lol)

Just wow! Amazing video from him as usual, but we could expect even native 4K@30-60fps or 1440p@60-90fps with the same demo when HW RT is utilized! What a madness!
I don't understand, are you trying to so that by utilising the dedicated RT hardware in the PS5 it will increase the frame rate and resolution because the other parts of the CPU/GPU won't be taxed as much?

EDIT: Just rewatched the video and now I understand what you mean, my bad lol

EDIT 2: oh shit, thats crazy when you think about it! lmao

I believe he is trying to say that software RT like UE does is way more taxing to GPU than if it used the hardware RT.

Bit that demo uses very little RT in Lumen... so I don’t know:

No clue there.

Yes, I mean they have to show it sooner or later but yeah we should see it then, possibly a sneak peek sooner of just a glimpse when they announce the showcase.

Who at epic is saying this demo would not be possible on series x?

I’m sure it could run with compromises. The demo was done to highlight the PS5s strength which is throughput that is double the XSX. Yet the original poster claims it would run with more polys on the XSX...that is impossible as the streaming is responsible for ridiculous number of triangles. You can’t run more with half the throughput...good luck. Then entire point of Sony‘s approach is to get away from ever increasing amounts of RAM. You can get your butt everyone will be following their approach.

The RT cores or as named intersection engines that are dedicated to lift most of the calculation out of CU's themselves:

Sony also shed some "light" on the hardware-accelerated real-time ray-tracing approach AMD is taking with RDNA2. Apparently, each compute unit features a hardware component called "Intersection Engine," with roughly the same function as an RT core on NVIDIA "Turing," which is to calculate the intersection of rays with geometry (such as triangles or polygons) in a scene. This combines with a fairly standardized bounding volume hierarchy (BVH) model to achieve a hybrid of ray-traced elements in an otherwise conventional rasterized 3D scene (pretty much where NVIDIA is right now with RTX). On PlayStation 5, RDNA2's ray-tracing hardware is leveraged for positional audio, global illumination, shadows, reflections, and full ray-tracing.


All of those were not utilizing the dedicated ray-tracing hardware (intersection engines) that should lift that weight way better. To see how with and without HW RT results are:

GTX 1080Ti is pretty close to RTX 2080 when there is no RT, but see how it's devastating with RT on (1080Ti needs to use software-based RT, adding more stress on the CU's). Even RTX 2060 beats it.
