Md Ray Md Ray ANIMAL1975 ANIMAL1975 I was kindly replying to someone. Now if you don't realize you guys are both of topic, please form your own thread. Rea Rea and I finished our convo long time ago. Unless you are talking about either GPU's I'm not sure why you guys keep derailing the thread?


Unreal Engine on Epic's pc vs Unreal engine on every other pc

Mine looks and runs like Epics build, as well as people running well before the minimum specs. Not sure why people are mistaking the editors performance for the baked demo. It's pathetic at this point to keep trying to peddle this nonsense.

You sound triggered Md Ray Md Ray Md Ray Md Ray go to bed.
No, I'm chill, breh. :messenger_tears_of_joy:
Before you jumped in, I was talking was about how we don't know how much RAM it's allocated to the OS.
Yes. But what does primitive shaders have anything to do with that? :messenger_tears_of_joy:
there's no indication of what it uses, but what would 2.5gb of RAM be out of the norm? Do you have any reason to believe otherwise? Md Ray Md Ray Md Ray Md Ray ??
Believe what? I've posted this already 👇
There's no word from Sony yet, AFAIK. But I'd imagine it's similar to XSX's 13.5 GB.
To address your concern, how is that downplaying ps5?
To answer your question, see your post: 👇
if I were using an outdated tech (primative shaders)
Bringing up something entirely different like primitive shaders when the question/discussion was about something else entirely. If this is not downplaying then IDK what is. :messenger_tears_of_joy:

No one brought up about primitive shaders in the first place but you, when the question was simply about usable RAM.

Why, what's the correlation between them...?
I'm not sure why you guys keep derailing the thread?

If you kept up with the thread, it was used an example with things that hasn't revealed, which was said along with it's absence of RAM usage. You could just read the thread to see what was said you know. Not sure what the act is for.


Now that it's been answered twice, you gonna get back on topic Md Ray Md Ray or further derail? Not every thread needs to be about PlayStation.

I hope you seriously wanna know about primitive shaders, they kill unnecessary data before it hurts the GPU/CPU performance, hence "primitive".

Yeah, i get that. We're all making an educated guess,
Zach Galifianakis Thank You GIF


but seems to me, OP sounds like 13.5 for ps5 is confirmed, so i just ask a simple question because i was genuinely curious. LoL. There is no downplaying other platforms or hidden agenda involved.
It was a genuine, curious question.

I came in here for some PC GPU discussion and see this is a thread about PS and XB.

Anyways, the results make sense and don't. These synthetic benchmarks are something I always don't like to gauge performance with unless it's just to see some metrics on specific things I want to compare my rig with others findings.

Some interesting results found by a youtuber.

  • 3090 at 4k outperforms 6900xt. 10-20% better performance.
  • 6900xt at 1440p outperforms 6900xt. 10-15% better performance.
  • 6900xt is only 20 Tflops. 3090 is 36 tflops.
  • VRAM usage at both 1440p and 4k resolutions is around 6GB. Demo Allocates up to 7GB.
  • System RAM usage at both 1440p and 4k resolutions goes all the way up to 20+ GB. Total usage 2x more than PS5 and XSX.
  • PS5 and XSX only have 13.5 GB of total RAM available which means their I/O is doing a lot of the heavy lifting.
  • 6900 XT is roughly 50-60 fps at 1440p. 28-35 fps at native 4k.
  • 3090 is roughly 45-50 fps at 1440p. 30-38 fps at native 4k.
6900xt 1440p

3900 1440p

4k Comparison. Timestamped.


And that's why i said at the reveal of the demo that PC will just use ram to swap the data in and out and more cpu cores unless it shifts to gpu from ( rtx i/o). Yet tech youtubers on the other end not even once.

Also found this.

Trees and dynamic, non-rigid objects add so much performance penalty as they're still rendered the old way. You should expect less than half the performance.

We should see real games to see if UE5 would provide the next gen promise.

That's such an odd example to use.

And then outright calling primitive shaders = outdated, without providing any data (visual/perf difference) as proof is hilarious.

This is pretty much on topic of the GPUs now. It's not about PlayStation. Primitive shader is an AMD GPU feature.

Regardless, its nothing to be upset about since this is all still in early access, things will improve and evolve over time, especially on PC where directstorage is still to come.

It bodes well that the 6900XT is providing double the performance of the PS5 even at this early stage.

Exactly. It is maddening. They are pushing this crap to games and it should go to movies.
50fps on 3090 in 1440p... for bare desert. Didn't UE5 promised to "optimize" the polygon count so it should give amazing performance with amazing visuals up close?
Death Stranding rocky lands are 4k120 and look amazing. I fail to see how this is so much better.... I understand it is "infinitely" detailed but cmon

PS5 was doing around 40fps at 1440p though, also cinematic assets, raw, zero optimization while using Lumen by software. Interesting if there is a console version to test.

Still UE5 needs sometime but it's a good start.

This is a sample project in an early access engine. You shouldn't expect miracles in terms of performance right now. It's basically running at ultra-extreme settings from the get go.

The performance is still crazy, as it is rendering soooooo much more polygons than any games to date. You can spam a dozen of these extremly high detailed ancient ones and performance still won't suffer. The Polygon count is out of this world. You need glasses if you think Death Stranding even remotely compares.

As for deformable meshes, support is coming. It is still early access after all. I don't think this will be a big deal at all, you will get tons of interactive stuff in future games. The post you quoted is incorrect about non Nanite stuff being rendered the old way. Eventually, it will be using mesh shading on PC and Xbox and primitive shading on PS5, which are much, much faster and better pipelines than vertex shading (what's used today). Future is looking very bright indeed.

yeah this is why we won't a released game made from strach using nanite and strength of it before long....
using v5 of the engine that's another strory.
Sadly poeple tend to mix the two and see thing not there when studio say they use v5

Another important thing I want to mention is that RT hardware-acceleration for Lumen is literally broken right now.

Lumen should get a great speedup once it's able to make use of dedicated hardware found in modern GPUs and consoles.

To me it looks laggy compared to normal RT as well, something like few cycles slow, maybe to make it less taxing? You notice it when you move the sun around.

Are you and the bandwagon gang all here yet? Y'all finish assembling the squad?


In 2017, to accommodate developers’ increasing appetite for migrating geometry work to compute shaders, AMD introduced a more programmable geometry pipeline stage in their Vega GPU that ran a new type of shader called a primitive shader. According to AMD corporate fellow Mike Mantor, primitive shaders have “the same access that a compute shader has to coordinate how you bring work into the shader.” Mantor said that primitive shaders would give developers access to all the data they need to effectively process geometry, as well.

Primitive shaders led to task shaders, and that led to mesh shaders.

Little is known about Sony's implementation of their geometry engine wich also houses their primitive shaders. What we do know, is that they've brought a lot of their own customization to it and comparing that to the older primitive shaders are probably not accurate.

Which was my main point before someone alerted all of you guys to come defend this thread. It's customized, yes, but a spade is still a spade at the end of the day. Who knows, it might even be better, but it still fits under primitive. They were pretty vocal about "SSD, SSD, SSD!!!", so it's a bit odd they have been on hush mode about this.

If you and your squad want to discuss this further, create a thread. This isn't really the place for discussion of you haven't noticed yet.

Eh. the S only has 7.5 GB of ram available for games. and the xsx and ps5 can only run it at 1440p 30 fps.

the S will probably run it at 800p if its lucky and doesnt have its 7.5 GB of vram become a bottleneck.
Couldn't they load half precision assets and set the resolution to meet target performance with that instead (I'm not sure how the data stored and if this is even possible)? It would still be more detailed than what we have now.

Also if this tech is heavily dependent on IO series x will not be able to overcome the throughput difference with extra memory so either:
- asset quality is reduced in advance so they fit in the budget (assuming that this is the limiting factor)
- pop-up galore will ensue when there are too many new objects to stream in


My guess is that we are about to reevaluate what our GPUs can and cannot do.

So the VRAM usage is already smaller than some current-gen titles, nice. RAM usage on the other hand skyrockets, but once DirectStorage is utilized that one will go down as well. And with DLSS it will be possible to play at 4K60. Great times ahead.

I've always been telling people VRAM consumption is not going to increase next gen, atleast when using techniques like Sampler Feedback and Nanite+Virtual Texturing.

These techniques allow for much higher fidelity without the need to increase physical VRAM.

thanks.

TheThreadsThatBindUs TheThreadsThatBindUs Three Jackdaws Three Jackdaws the 570 which is roughly on par with the 4 tflops series s (1.5x IPC gain over Polaris) is doing 10 fps at 1440p. this is likely an 800p game to hit 30 fps.

In the other thread, Alex mentioned how Lumens is software based and is equivalent to Medium Settings. High Lumen settings is hardware accelerated using RT cores and can only do 1080p 30 on both the PS5 and XSX. this would put the series s version at 540p 30 fps.

It looks like series s isnt going to be holding back next gen. Devs dont seem to really care that it exists and are just content with pushing fidelity instead of resolution and framerate.

I am not sure but I think that rasterization in UE5 uses GPU compute shaders to draw meshes and not the hardware accelerated mesh shading (or the equivalent of geometry engine of the PS5).

My speculation is that it shifts some shader work to draw polygons.
I might be completely wrong though.

Edit: The unreal engine 5 demo for PS5 might use the geometry engine instead.

Primitive Shaders are far from outdated, they actually offer the same functionality as Mesh Shaders do which is to bring compute shader functionality into the graphics pipeline. The underlying hardware for Mesh/Primitive Shaders is also the same, in fact AMD have not highlighted any changes to their geometry engine and command processor since Vega and the Mesh Shaders (which are simply an API implementation) are converted into Primitive Shader code on all RDNA 2 cards and this very likely includes the Series X/S.

Now Primitive Shaders modify the graphics pipeline while Mesh Shaders intend to replace it all together, which one is better? not really a good question since both offer the same functionality and performance when coded and optimised correctly, I know that tessellation can be programmed a little bit easier with Mesh Shaders but that's about it.

Unreal Engine 5 doesn't offer support for Mesh Shaders as far as I'm aware, I know that they use "hyper optimised compute shaders" which were featured in the PS5 demo last year and the same demo also featured Primitive Shaders according to Epic.

thanks.

TheThreadsThatBindUs TheThreadsThatBindUs Three Jackdaws Three Jackdaws the 570 which is roughly on par with the 4 tflops series s (1.5x IPC gain over Polaris) is doing 10 fps at 1440p. this is likely an 800p game to hit 30 fps.

In the other thread, Alex mentioned how Lumens is software based and is equivalent to Medium Settings. High Lumen settings is hardware accelerated using RT cores and can only do 1080p 30 on both the PS5 and XSX. this would put the series s version at 540p 30 fps.

It looks like series s isnt going to be holding back next gen. Devs dont seem to really care that it exists and are just content with pushing fidelity instead of resolution and framerate.

The results are interesting, I'm kind of surprised at the performance cost of Lumen considering it's a software solution, but then again true dynamic bounce global illumination is very expensive on the GPU.

Until we actually see something running on XSS and PS5/XSX it is very presumptuous to assume anything. Epic themselves stated that while they targeted 1080p/30, 1080p/60 (or presumably higher resolutions) were possible and expected. You might see the XSS running at 30fps with a similar fidelity target as XSX/PS5 at 60fps. Taking an old GPU that might lineup in theoretical TF count when adjusting for ipc increases is not indicative of performance on a part with modern accelerators (that only holds for old software). This can easily be seen by trying to run WDL on the 570 with equivalent RT as the XSS.

It will be something interesting to see in 3rd-party UE5 releases, especially in seeing the approach taken. Will they lower fidelity of Nanite/Lumen to work with XSS (can Nanite/Lumen be used on the XSS?), or do they auto-generate LODs and continue to work more traditionally with XSS?

Eh. the S only has 7.5 GB of ram available for games. and the xsx and ps5 can only run it at 1440p 30 fps.

the S will probably run it at 800p if its lucky and doesnt have its 7.5 GB of vram become a bottleneck.
Eh. The engine will be optimized more and more over time and it will run on cell phones. As every unreal engine since the beginning. No need to worry.

Has anybody been able to get the requisite SDK installed and package this into a standalone .exe, or does anyone have a link to where somebody has been able to do this?

The whole point of UE5 early access is so devs(from hobbyist to professional) can get a look at UE5 functionality and start pushing development towards that. It's not meant to be console fanboy fodder.

Is there any confirmation that PS5 usable RAM is 13.5GB? I only found that XSX is confirmed 13.5gb for games.
No. Folks just assumed since thats the case for MS then that must be the case for Sony. In fact since the PS5 SSD is much faster they don't need to allocate as much ram to the OS as MS. Rumor is the PS5 allocates 2GB to OS thus leaving 14GB available for games.
