AMD FSR SDK 2.2 released with FSR Upscaling 4.1 and FSR Ray Regeneration 1.1

It appears that they didn't replace the girl's face, so should be ok.

So ML to unblur the blur added by the other pass of ML.

I wonder what the "next level" of this stuff is. I don't see a push for 8K - everyone I know is either happy with 4K or even lower. My monitor is only 1440 and while I'm sure I'll go to 4K someday, it won't be any time soon. So what I'm getting at is, if they've built a tech that is all about upscaling but we end up staying at 4K (forever?) what is the upgrade path? I can't see them shrinking the source much. I would doubt you'll see 360p rasters scaled _well_ to 4K.

Further, I wonder if you replaced all the "wasted" transistor space on these chips for raw raster, what kind of numbers would we be getting? It might not be more/much more, but I would expect similar results minus some of the *-tracing stuff. Which, everyone I know turns off anyway.

8k is officially dead (for now at least). The manufacturers aren't making them at all anymore, so you can't buy them even if you wanted to (which you shouldn't.) -- https://arstechnica.com/gadgets/2026/01/lg-joins-the-rest-of-the-world-accepts-that-people-dont-want-8k-tvs/

I do live video streaming engineering as my career. I can tell you first hand that the VAST majority of content I handle is still 1080p. Like probably 95%. Occasionally we will get a 4k ingest, but it's not often. For decent bandwidth, you also need a 4k signal to be hevc 265, whereas a 1080p signal is just fine on good ol ancient avc 264. For stuff in post, a lot more is rendered out in 4k and streamed out in 4k, but even for some of the edits our team does, a lot of the source is delivered in 1080, and then they upscale it on the render so it's just fake 4k LOL

It isn't about going lower and lower render resolution, that just happens because more stuff is rendered, but your PC stays the same.

It isn't about upscaling, it's about managing what to do during the limited time. Instead of brute-forcing all the pixels, they could render less pixels and do more complex render. Instead of lowering the quality of the world, they could just lower the render and upscale it.

There is no point of adding more resources for raster if all that developers want to do is more raytracing.

FSR 4.1 is already available as DLL, which you copy in your game prefix.
Newest-Beta OptiScaler and Proton-CachyOS can do this, too, afaik.
It does also work for RDNA3 via FP8 emulation as did FSR 4.0 before.

My hope, perhaps, maybe, if possible... a new INT8 DLL for RDNA2, that would be great!

Does it mean that FSR4 is now open source, and will be usable for Nvidia cards too?

Same here. I think of 1440p as being the happy medium between 1080p and 4k, giving you a slightly crisper image, without the overhead that 4k requires.

When it comes to games, I can play at 1080p without complaint. I'm not exactly the most difficult person to please on this front. I mean sure, I can see the difference 4k makes, but it's not so much better that I feel the need to spend $1500+ on a new GPU.
