That's great news for the Steam machine.

So that's why my Rog Ally X was doing a little dance this morning.

How can anyone say it can't when there is a leaked version that factually runs?But according to neogaf "experts" RDNA3 can't run FSR4.1

Worse than that. These "experts" say RDNA2 can't run FSR4.

My Steam Deck thanks you. No more optiscaler needed. \o/
Asha has an opportunity to demonstrate that she "hear you" and wants to improve the experience on the Xbox Series as much as possible. There are no technical impediments preventing the XSX from benefiting from FSR 4.1.
On the other hand, the Xbox Ally X could also see a significant benefit as early as July.

yup. Microsoft needs to push for this too happen as quickly as possible

I forgot who exactly, but there was literally someone who said that didn't count because it wasn't official.
Clearly, it wasn't going to do anything to boost console sales at this point, but it would definitely be a game-changer and strong proof that they're truly prioritizing the console experience again and winning back user appreciation. It would be laughable if they had included specific hardware that made the Xbox Series X's APU more expensive, boasted about that feature against the PS5 at the beginning, and now aren't using it to their advantage. Its implementation would surely require less work than some of the latest new OS features.
P.S. It would be stupid not to benefit when they could. The other option would be if they couldn't due to problems unrelated to the technical aspects...
It's not just their marketing. NVIDIA is generations ahead of AMD in terms of software. Yes, AMD does release their stuff so it works on non-AMD hardware. But that's because they have to. Why would devs support AMD if it was proprietary, when they could just support NVIDIA's solution that has 10x the market share?

No. It doesn't support DP4A.

Its not a FULL RDNA2
If they decided to do it, only the XSX could be capable due to its specific hardware.
It would be up to Xbox to implement FSR 4.1 in the GDK because there are no technical obstacles preventing it. The only other possibility is a lack of will (which would be laughable since it was included precisely to differentiate it from the PS5 and they touted it extensively) or other specific circumstances.

Devs could in theory implement it on their own, without needing MS.

PS5 - no, RDNA1 limitations ( ͡° ͜ʖ ͡°)
XSX - could get it, but most likely it would be too slow vs. FSR3.1 (performance hit on RDNA2 i larger than on RDNA3).

Why does it have to be in the GDK? Devs could pull it off themselves if AMD releases it, right?If they decided to do it, only the XSX could be capable due to its specific hardware.

FSR appeared in PS5 games before it was implemented in SDK, so yeah. It's just software.

Damn. I guess Pro's value prop would still be justified.
With regard to performance on XSX, it seems the hit isn't that much compared to the gains in IQ? Had seen some RDNA 2 tests back when the leak happened. Was heavy, but looked leagues better. They could potentially reduce resolution further and still maintain the same performance targets.

Yes, they could drop internal res and still achieve better results.
But developers don't really care about image quality, we still see many games using fucking FSR1...

Or is it just one of Phil's balls in my throat?
No developer is probably gonna leverage this for console, but this could be pretty good for Series X|S if they would.

The first release of FSR4 Int8 mod, that several channels tested, had a bug that caused performance losses.
The newer FSR4 Int8 dll, version 4.0.0C runs significantly better.
For example, this is a RX6600, a 9TFLOP GPU, running the new dll. The Series X is 33% faster.
Now consider that Optiscaler has an overhead and on top of that AMD will probably be able to better optimized the code for RDNA2. So the official release will probably have a lower time.
I doubt the Series X would be able to do 1080p to 4K at a reasonable upscale time. But 1080p to 1440p would probably be feasible and look better than FSR3.
Also, AMD might not do the full fat FSR4 Int8 for RDNA2, but a distilled version, similar to what Intel did with XeSS DP4A.

They should have done this when they launched FSR4. Instead, they chose to be anti-consumer by forcing people to buy their newest GPUs when RDNA 3 chips were still on the market.
While it's good that they're correcting this, it's coming pretty late.

It's not mandatory for developers to use it, but being part of GDK greatly simplifies and automates its implementation. In other words, being part of GDK would significantly increase the likelihood of implementation by studios and developers on XSX versions compared to a situation where it depended solely on the willingness of said studios and developers.

PS5 lacks the RDNA 2 features to run this. XS S/X could get it in theory but I don't think anybody cares to implement it.

Fair point. Especially when the thing isn't supported on base PS5 "will devs bother?" is a big question. Like many stated, a lot of them are sticking to freaking FSR 1...

I don't think even Microsoft cares at this point for their "old" hardware so I have a hard time seeing any developer bothering, but we'll see.

One thing doesn't have much to do with the other.
When they finally managed to achieve decent upscaling, they decided to make it exclusive to RDNA 4. The argument was that only this generation of GPUs would be capable of running FSR4.
An AMD developer accidentally released a version of FSR INT8, compatible with RDNA 2 and 3, on Github. This quickly spread, and tests showed that older GPUs could run this version smoothly and achieve improved image quality.
On Linux, the Proton developer even worked on a converter so that any game with FS4 would universally run on older GPUs. The feature was forced to remain hidden due to "forces beyond its control," according to the developer. But the community took advantage of it, and it even appeared on Windows with Optiscaler.
And so, throughout 2025, whenever AMD was asked about FSR4, it continued to say that it was only for RDNA 4. Add to that the fact that driver development for older GPUs had entered "legacy mode".
And the final blow was the announcement that the future FSR5 would also be exclusive to RDNA 5. For consumers, this leaves the impression that it's not worth buying AMD because the support is poor. And this was reflected in the ever-decreasing market share.
The point is, for someone who's behind, this kind of strategy is suicide. Since the launch of FSR4, 12% of the market share has been lost.

So where can I send Sony a Thank You letter for spending the time and money on PSSR?
