AMD Announces FSR 4 Updates Project Redstone

[btarunr]

AMD in its Computex 2025 keynote address announced an overview of FSR 4 implementation. FSR 4 introduces a new AI Machine Learning-based super resolution algorithm that's more accurate, and vastly improves image quality at every performance preset. AMD also announced FSR "Project Redstone." This is a future version extension of FSR, and "Project Redstone" is its working title. "Redstone" combines the AI ML super resolution introduced by FSR 4, with three new features—neural radiance caching, an AI ML-based Ray Regeneration, and AI ML-based Frame Generation. The company plans to launch "Redstone" in the second half of 2025.

All three features being introduced by "Project Redstone" aim to achieve technological parity with NVIDIA DLSS 3.5 and DLSS 4, particularly in AAA games with ray tracing enabled. Neural Radiance Caching sees an AI ML model continually learn how light bounces in a scene to predict and store indirect lighting, which reduces the performance cost of ray tracing. AMD FSR "Redstone" Ray Regeneration is functionally similar to NVIDIA DLSS 3.5 Ray Reconstruction. It uses a neural network to regenerate pixels that couldn't be accurately path-traced. This should improve the quality of reflections, particularly when super resolution is used. The next big announcement of course is a new AI ML-based model for Frame Generation.



AMD has been using a slightly spruced up interpolation technology as its take on Frame Generation, which it introduced with FSR 3. With "Project Redstone," AMD is replacing this method of frame generation with a new ML-based model that incorporates temporal and spatial awareness to generate interleaving frames with greater accuracy and image quality. This isn't multi-frame generation, but the 2x frame-rate doubling NVIDIA achieved with RTX 40-series "Ada," but with greater image quality.



AMD announced that over 60 game titles support FSR 4. Integrating FSR 4 is as easy as it was for game developers to integrate FSR 3.1, so it should be fairly straightforward for devs to push patches to their existing FSR-enabled titles to support the latest version.

Begun, the AI rendering wars have.

"AMD announced that when FSR 4 goes live on June 5th". It's not available yet according to AMD then? What am I using on my 9070 XT then?

 

[badepaz]

What kind of uninformed reporting is this…? FSR 4 has already been available since March. It launched with the RX 9070 XT. It looks like AMD will be adding new features to it along with more supported game titles, but FSR 4 is available NOW. That slide you re-posted says FSR 4 was made available in the 1st half of 2025…we are IN the first half of 2025 right now. It’s FSR Redstone that’s in the 2nd half of 2025. Sorry to repeat myself, but we’ve been using the ML upscaler of FSR 4 since March. It’s the ML Frame Gen that’s coming with redstone. June 5th is when the 9060 XT launches.

The person who posted this doesn’t know what he’s talking about. FSR 4 has been available since March. It’s the ML based frame generation and a couple of other things that are coming 2nd half of 2025. June 5 is the date when the 9060 and 9060 XT launches - not the update to FSR.

I am confused too!

 

[badepaz]

I am confused too!

Don’t be. This article is wrong. FSR 4 is already available. It’s an UPDATE to FSR that’s coming the 2nd half of 2025. June 5th is when the 9060 XT GPU launches.

I believe this has happened in the past where what people had access to was viewed by AMD at least to be in a preview/beta sort of phase and not completely and officially 'launched', I wonder if that's the case here.

FSR4 really does look great and is massively useable, so they really need to double down on adoption, for instance DOOM Dark Ages not having it is a massive wasted opportunity.

This is not uninformed reporting, inasmuch as an indirect admission that their FSR 4 deal was oversold and underdelivered. What you've had is an early, undocumented implementation of it that relies on the driver intercepting and replacing FSR 3 code. This should be, at least from what I understand, a proper implementation and documented feature-complete release of FSR 4, complete with support from the FidelityFX SDK so game developers can implement and tune it themselves - as it should have been from the start. AMD can't devote the resources to test and maintain the current implementation because it relies on code injection, especially over time as games get updates and the driver code itself changes.

Adding ray reconstruction and ML-assisted frame generation should bring this up to parity with DLSS, and it's good to hear of the neural shaders also being supported. All that will be missing is 3x and 4x rate frame generation, which should be more useful on this level of hardware compared to something that's vastly more powerful like a 5090... but ultimately not a dealbreaker if you ask me.

 

[Rhosta]

Even if 5th June availability meant it is going to be available in 60 games. It seems unlikely given that it is currently available only in 44 games. I doubt we will suddenly see support for 16 more games two weeks forward.

Which brings me to my second point. FSR 4 is dead technology. Simply because they restricted its compatibility only to latest gen of their cards. The only reason devs bothered to implement FSR 3 is, because it ran on Nvidia cards. Why would anybody implement technology almost nobody is going to use? That's a waste of ever so scarce resources in games development industry. Redstone should be mainly about extending its support to older gen cards and to Nvidia cards.

Mmmm, I wouldn't go that far. With a proper SDK, it can enable features selectively, therefore the same implementation would runs on earlier AMD architectures or other vendors' products, just not producing the same level of image quality that it would on an otherwise full FSR 4 implementation. DirectSR should simplify the deployment of upscaling engines on DirectX games, which will alleviate that concern somewhat. It's similar to what Nvidia wanted to achieve with Streamline, but AMD opted out of supporting their competitor's solution (unsurprisingly).

 

[JustBenching]

It's good we are getting progress with upscalers. Let the wars begin

EG1. But nvidia and I assume AMD need to make it easier to enable. Im not going to go into inspector and play around with presets and whatnot to get dlss 4 / fsr 4 working. Im paying, you do that for me, pleasekthanksbye.

That’s a kind way of looking at it. For the article though, it’s just that the person who wrote it just put a lot of things down without being informed. In his defense, he probably doesn’t follow AMD.

I went back and re-watched AMDs presentation, and I see where part of the writer’s confusion is. Right after they got finished talking about “FSR Redstone”, they then followed up on a slide showing the number of FSR 4 games going from 37 to 60 on June 5th. So for someone who hasn’t followed AMD and is just trying to get an article out quickly, I can see where things would get mixed up. Going back and forth with these acronyms and slides and topics, and so on, could be confusing for someone who isn’t super familiar with AMD products.

So here’s a summary.

- March 6, 2025 - AMD launched the 9070 XT and, along with it, FSR 4 and its Machine Learning Upscaler. (Around 30ish games supported at launch - 37 at this moment in time)

- June 5th 2025 - over 60 games total will support FSR 4

- June 5th 2025 - 9060 XT GPU will launch

- Some time in the 2nd half of 2025, “Redstone” will launch. Maybe they’ll call it “FSR 4.1”? Maybe?
Redstone will have more ML features added to go along with the ML upscaler that is already present in FSR 4.0. The three new things will be Neural Radiance Caching, ML Ray Regeneration, and ML Frame Gen.

This is kind of in-line with AMDs past approach of starting off with some features and adding value over time with driver and software updates. Like how FSR 3.1 brought Native AA to the existing implementation of FSR 3. That’s why I’m guessing the final name for these new features will be FSR 4.1 - it would follow the precedent of FSR 3. They may have wanted to put these features in the original FSR 4 implementation but just got behind and didn’t want to hold up the new GPU line. I’m a software engineer, so I get it - things get behind sometimes for various reasons. But we still want to get our products out. AMD hasn’t said anything about wanting to change the upscaling feature, and everyone I’ve seen review it has had nothing but high praise for it. Digital Foundry was singing its praises since it was first previewed at CES. Many say, while it doesn’t come quite to DLSS 4 quality, it’s close, and looks better than DLSS 3 in many cases. So FSR 4 isn’t beta or pre-release. It’s just the first version with more updates to come.

Here we are with proprietary, vendor locked tech driving core rendering advancements, instead of commonly developing them in DirectX etc. We will have a dark future where specific games will practically only be playable on either Nvidia or AMD, which partially already is true. Thanks Nvidia RTX and your curse of proprietarization...

 

[WatchThe80s]

Nice! When we get this to all the games that has FSR 1.0, 2.0, 2.2, maybe 3.0, 3.5? Never? Probably.

I wasn’t saying AMD was “uninformed”, I was saying the person who wrote this article was “uninformed”. He said FSR 4 was coming on June 5th. That’s incorrect. It’s already out. June 5th is the date more games are going to be added and when the 9060 XT will launch. I get that media outlets want to rush to get their articles out for clicks and views, whenever there’s some kind of tech event or some breaking news. But if a person doesn’t have all the facts and is going to write things that are incorrect, they shouldn’t write it all - at least not till they’ve done their research.

I agree with you about features: I was a little disappointed that they didn’t have ray reconstruction as part of the initial implementation of FSR 4. It’s good to have them bringing their ML stuff up to parity with Nvidia. Maybe better feature parity and competition will push Nvidia to bringing their prices down. Probably not - but it’s a nice thought. Multi frame gen is nice I guess, but not something I’m personally concerned with. I don’t mind the “fake frames” that others complain about, but I just don’t see where more than 2x would be useful to me and my games. But I also agree, there mfg is probably more important to lower powered hardware than a beast like the 5090.

In general, though, I don’t get into this brand loyalty hate thing that I’ve seen a lot of computer building enthusiasts get into. I don’t have any personal hate of Nvidia, nor do I hate AMD. In general I like AMD products, but I think the Nvidia control panel is much easier and nicer than Adrenalin. I like how Nvidia has had ray reconstruction - and I like how AMD still uses 8 pin PCI-E connectors. The point is, I can appreciate the good of all brands, while also acknowledging the bad; I just like to buy things that make me happy. And my 9070 XT has made me a happy gamer. And i personally really like the quality of FSR 4 upscaling. Native AA (or DLAA for Nvidia) is a nice thing too since most of the games I play I play on my 1440p monitor and I don’t really need the upscaling part. Even on my 65” 4K OLED I don’t always need the upscaling. I don’t really mind the driver toggle.

Of course, we’re all entitled to our preferences and opinions. The world is big enough for both AMD and Nvidia GPU gamers . It’s also nice that intel is making some good competitive budget GPUs.

The alternative is what AMD did with FSR1-3, resulting in noticably, consistently worse IQ in many different ways, for years (to the point where DLSS Balanced looks better than FSR Quality, leading to what, 20-30% extra performance), besides the complete lack of feature parity. Those versions are still available if you want something that runs on any old potato and don't care about the IQ issues, but even consoles and phones, which previously used versions of FSR, have shifted towards their own proprietary solutions, presumably to get better image quality. AMD following suit as NV and requiring specific AI and math hardware is because that is the way to get actual good results, which is obvious.

If a game has FSR >= 3.1 then it will support FSR 4 automatically unless it's not whitelisted yet. Complain to AMD about that.
If a game has FSR < 3.1 then Complain to the developer or use Optiscaler.

Optiscaler which currently supports enabling FSR 4 in 207 games and counting. I've used it with great results in: Lies of P, Lords of the Fallen, Mount and Blade II, Clash Artifacts of Chaos, Tiny Tina's Wonderlands.

At this point I'm convinced that FSR 4 and DLSS 4 could be ported to Nvidia and AMD respectively as the required hardware is there. Of course they will remain separate and duplicate each other's work because of all the sunk R&D costs and vendor politics.

How does that make it dead technology? These are the cards people are buying going forwards. To release it for let's say 6000 series only would make it dead technology.

Many, many people bought a 9000 series card so far so idk why you think hardly anybody will use it.

It's good we are getting progress with upscalers. Let the wars begin

EG1. But nvidia and I assume AMD need to make it easier to enable. Im not going to go into inspector and play around with presets and whatnot to get dlss 4 / fsr 4 working. Im paying, you do that for me, pleasekthanksbye.

We shall reap the rewards!

I actually feel like AMD has a massive point to prove and a reason to push forwards with the amount of 9070/XT's they've sold so far, especially with Nvidia in the press for all the wrong things recently. Surely they recognise this too.

There's no update coming June 5th.

I wish one morning both companies would wake up and drop FG completely...

 

[Event Horizon]

FSR Redstone is coming in "2H 2025". Maybe they'll time its release with the SDK with full Vulkan support.
