Cerny didn't make FSR4.
It was made by AMD, and will be adopted by Sony and PS5 Pro in a future PSSR update.

I believe it was collaboration. AMD were clearly struggling on their own before the partnership.

This is what pssr should've been. Cerny didn't need to go off and do his own thing as admirable as it sounds. But the results have not been there.

Yes, it's the first results of the Amethyst collaboration.
Though each company uses different tensor cores.

Eurogamer article

"The neural network (and training recipe) in FSR 4's upscaler are the first results of the Amethyst collaboration," Cerny told us. "And results are excellent, it's a more advanced approach that can exceed the crispness of PSSR. I'm very proud of the work of the joint team!"

The first iteration of FSR4 is clearly AMD only. Otherwise it would also be available on the Pro.
Eventually, a version of FSR4, made under amethyst project, will come to the Pro.

They didn't have an ML-accelerated solution before this. NVIDIA kind of forced everyone into it in a way, but yeah, it is a partnership.

 

[SlimySnake]

On topic, it sounds like fsr4 quality is somewhere between dlsse and dlss4.

I've not been using dlss4 because of the performance hit and several issues with artifacts and am wondering if i would be able to use fsr4 instead of dlss3 going forward.

Stop licking that butthole man….stop polluting pc thread.
You don't see me in every PS5 thread saying that those game don't have pathtracing on those low cost devices

 

[winjer]

So Cerny is wrong and you are right somehow? Ok

Cerny is correct. But Amethyst started at a later date.
Just consider that the Radeon 9070 and FSR4 were released over a month ago and there is no FSR4 on the Pro.
The collaboration probably started when Cerny made that interview. So it will take some time until we see the results of such collaboration.
And it will be beneficial for AMD and Sony.

 

[Gaiff]

Seems FSR4 is about as taxing as DLSS4, even a bit more.

 

[winjer]

Seems FSR4 is about as taxing as DLSS4, even a bit more.

Or the Tensor Cores in RDNA4 are not as powerful, so they take more time to process each frame.

 

[Amey]

Higher input resolution results in better upscaled image. Mind Blown!

 

[Fafalada]

Seems FSR4 is about as taxing as DLSS4, even a bit more.

That's not really a statement that the data we have supports.
What we see is that 'relative to base performance, FSR4 on supported AMD hw is about as taxing as DLSS4 on latest NVidia hardware', at what is 'perceptually' a similar level of quality (No outlet has so far applied quantifiable quality tests to any of these to date) - basically we're not comparing FSR and DLSS at all, we're just comparing the GPUs.

For your statement to be relevant - we'd need measured performance of algorithms themselves (NVidia has shared those numbers with DLSS4 - AMD did not) and divide that with tensor performance on a specific hw-target to get cost that could be compared across algorithms. This wouldn't control for architecture specific gotchas - but it's the closest we can get given the exclusive nature of these two.

 

[Fake]

FSR4 can act as a AA, so no surprises here.

The same happens with RDR remastered.

 

[mckmas8808]

This is what pssr should've been. Cerny didn't need to go off and do his own thing as admirable as it sounds. But the results have not been there.

FSR4 can NOT run on the PS5 Pro. Hence.....yes he did need to make PSSR.

Cerny stated that FSR4 will be used in PS5Pro in 2026.

 

[winjer]

If the collaboration had started much sooner, then Pro would already be using the FSR4 code.
Instead, it will only use FSR4 next year.

 

[Loxus]

Cerny stated that FSR4 will be used in PS5Pro in 2026.

I thought this is what he actually said?

"Our target is to have something very similar to FSR 4's upscaler available on PS5 Pro for 2026 titles as the next evolution of PSSR"

 

[mckmas8808]

Cerny stated that FSR4 will be used in PS5Pro in 2026.

True, but it'll be a "version" of FSR4. And the PS5Pro released in 2024, so PSSR was needed for those 2 or so years.

Strange, you are getting artifacts with the Transformer model but not with the CNN model.

And the perf hit is high enough that you would rather use DLSS3?


In my own testing DLSS4 Balanced looks better than DLSS3 Quality and performs about the same if not better.

*Using an RTX4080.



P.S
FSR4 looks most like DLSS3 tier for tier if your GPU performs better with FSR4 then you might as well switch to FSR4 for however many frames you are gaining.
Otherwise just go a tier down using DLSS4.

You are correct, but I was really just taking a more practical approach. ie, we have two GPUs with similar levels of performance with upscaling of a similar quality. I suppose I should have instead said that DLSS4 on a 5070 Ti is more efficient/less demanding than FSR4 on a 9070 XT. At least, based on that 4 games sample.

Or the Tensor Cores in RDNA4 are not as powerful, so they take more time to process each frame.

Are they called Tensor Cores? Thought this was patented by NVIDIA. Techpowerup calls them Tensor Cores, but no documentation from AMD calls them that.

Pls bring to RDNA3 cards

Sony announces new 'Amethyst' collaboration with AMD to develop 'machine learning' technology in games

'Amethyst' will be a "multi-year" collaboration

www.techradar.com

I think it's safe to say the collaboration started sometime in 2024.

"With Amethyst, we've started on another long journey and are combining our expertise with two goals in mind," Mark Cerny said.
"The first goal is a more ideal architecture for machine learning. Something capable of generalized processing of neural networks but particularly good at the lightweight CNNs needed for game graphics and something focused around achieving that Holy Grail of fully-fused networks."
Cerny explained that the second goal is to develop "in parallel, a set of high quality CNNs for game graphics" to will help further graphical capability. "Both SIE and AMD will independently have the ability to draw from this collection of network architectures and training strategies, and these components should be key in increasing the richness of game graphics as well as enabling more extensive use of ray tracing and path tracing," he said.

I think it's safe to say the collaboration started sometime in 2024.

But it's not ready on the PS5 Pro, while it's ready on RDNA4 GPUs, for over a month.
So it's clear that AMD started work on FSR4 much sooner than Sony.
Chances are that Sony saw that FSR4 was superior to PSSR and decided to ditch it and join AMD in developing FSR4 for the Pro as well.

There are so many coincidences

RDNA2 with Ray Tracing acceleration, the first product announced with this is the PS5.
RDNA4 with hardware-accelerated FSR4, announced at the same time as the PS5 PRO, hardware acceleration for AI, is the PS5 PRO

AMD's biggest leaps are with the launches of the PS5 and PS5 PRO

But Sony has nothing to do with this and much less collaborated with AMD to make this possible

It is obvious and evident that FSR4 and PSSR are both byproducts of AMD and Sony's collaboration.

Sony used PSSR because on consoles in general the FPS is fixed and the resolution is variable.
AMD uses FSR4 because on PC in general the resolution is fixed and the FPS is variable.

AMD's main GPU customers aren't PC gamers, they're Sony and Playstation gamers. And be happy about that, it means AMD's focus is on people who play video games. Not like Nvidia who makes GPUs for AI and the waste becomes GPUs for PC games.

RDNA2 RT was a response to Nvidia's Ray-Tracing that came out in 2018 with Turing.
RDNA4 has different Tensor units to the ones in the PS5 Pro.
And FSR4 is much better than PSSR.

Almost every advancement in the GPU market, in the past half decade was done by Nvidia.
RT cores, Tensor Cores, AI upscaling, Mesh Shaders, Variable Rate Shading, Frame generation, Ray reconstruction.
Even with Nvidia focusing on AI and servers, they are still the leaders in GPU tech.
What AMD has been doing is catching up. And Sony uses hardware designed by AMD.

Tensor is a mathematical operation, so anyone can use it.

Nvidia calls them Tensor Cores.
AMD calls them AI Accelerators.
Intel I believe calls them Vector Engines.

They effectively do the same thing but yeah they use different naming schemes.

 

[Xyphie]

Are they called Tensor Cores? Thought this was patented by NVIDIA. Techpowerup calls them Tensor Cores, but no documentation from AMD calls them that.

They already call their Tensor Core-equivalent Matrix Cores on their CDNA GPUs. What RDNA4/RDNA3/PS5Pro does isn't a Tensor/Matrix Core but MLOPs running on their shader core. Likely we'll see them bring that with UDNA.

i think we PS owners will be eating good on the ps6.

Same. They need a big card tho. Not going backwards from 24gig VRAM.

Not that shocking, its close to DLSS 4 but not quite there.

Next few releases should be really good.

 

[Fafalada]

Almost every advancement in the GPU market, in the past half decade was done by Nvidia.
RT cores, Tensor Cores, AI upscaling, Mesh Shaders, Variable Rate Shading, Frame generation, Ray reconstruction.

I don't think there's any disputing NVidia leadership in GPU space (market share aside - they dominated the news and mindshare for a reason) but I wouldn't attribute a bunch of individual things to them at all here.
Mesh Shaders were a DX construct and GPU vendors were 'compliant' with them (from hardware perspective, drivers took awhile) years ahead of the spec being there. Frame Gen (for games) predates AI or even programmable GPUs by quite some time, and VRS is a conceit of MSAA hardware that dates back to early 00s (we literally had games shipping with Tier-0 VRS throughout 00s, and beyond).
Hell PS4 Pro 'invented' a variant of its own specifically for VR acceleration (and yes this was apparently Pro exclusive, to my knowledge no AMD gpus shipped with it later), and I could be wrong, but timeline wise I remember Intel demoing Tier-2 VRS before anyone else did (the hope was after all that it would change fates for low-end hw - which didn't materialize - but anyway).

I do think we have NVidia to thank for AI accelerated pixel treatment being so widespread (and go beyond reconstruction), and their investment into RT absolutely helped bring that forward ahead of the market being ready for it. They were slow at getting adoption - but without their push, who knows if current gen of consoles would have bothered at all, let alone mobile hardware and beyond.

 

[SlimySnake]

What kind of artifacts?

• Squiggly lines on zebra crossings in cyberpunk.
• Shimmering artifacts on godrays through trees in kcd2.
• Similar issues with distant foliage in virtually every open world game with foliage i tried though i did not try it in ac shadows since its already so heavy.
• Blocky artifacts in Space Marine 2 when alpha effects are in play which is all the time since the game is so effects driven. especially in the distance.

this was back at launch a couple of months ago, so maybe things have improved since but im barely able to do dlss quality in these games. makes no sense to take a big performance hit and drop down to dlss 4 balanced or performance anyway.

 

[Loxus]

I'm reading a lot of different stuff about UDNA, but Kepler has a solid track record, so I'll take his word for it.
