AMD Announces FidelityFX Super Resolution (FSR), its DLSS-rival

AMD finally made a big announcement on its ambitious FidelityFX Super Resolution (FSR) technology, the company's rival to NVIDIA's popular DLSS. Much like it, FSR aims to significantly improve gaming performance with minimal loss in image quality, through a sophisticated supersampling algorithm. At this point, AMD did not detail the nuts and bolts of the feature, but mentioned how the feature could look to gamers.

There are four FSR presets typically available to a supported game—Ultra Quality, Quality, Balanced, and Performance, which AMD claims offer performance gains of 59% for "Ultra Quality," 102% for "Quality," 153% for "Balanced," and 206% for "Performance." These should come particularly handy when playing games with raytracing on; and were measured on "Godfall" with RX 6800 XT, with 4K "epic" preset, and raytracing enabled. As of now, the company is working with over 10 game studios and game engine developers to integrate FSR, and the technology is expected to support "over 100 CPUs and GPUs."
The FSR slide-deck follows.

This is AMD's signature move. Announce something open standard but next day you know it's optimized only for AMD and competitors have to optimize code by themselves and rebuild their hardware architecture.



And damage is done. For illiterate people AMD good, Nvidia bad.

*facepalm*

FSR will be open source, so Nvidia can look at the code and tweak their drivers accordingly. There isn't any specialized HW involved, it runs on shaders.

Did Nvidia tweaked its effects for AMD? Hairworks, PhysX, Gameworks...or AMD had to optimize their drivers themselves for proprietary closed source libraries.

I guess AMD could do it for them, if Nvidia open its software and hardware stack. :laugh:

I wonder if what you posted really made sense in your head.

RecusBut Scott Herkelman at CES 21 said it just works.

Only because many still using 3000. What about 1000, 2000, X370, X470, RDNA1? No FineWine?
Talking about ReBAR? It's on x470 and some B450, and works on 2000 series chips on some boards (with lower %, but it works)

As to the quoted image and the listed support, the 'select 3000 series' is because the 3000 series APU chips use an older tech - which complicates that.

lasLooks great I hope support will spread fast.

I hope it's not cherry picked numbers. Godfall is a terrible game. More like a playable tech demo.
Why would you say that? I like the game and its none of what you said. It gives a lot of fun. Sure the story may not be rich but the games is great and the movement and combat is awesome.
Why is everyone picking on this game I don't get it. Also strange brigade same thing.Whenever AMD excels in a game, some people will always call the game demo.
Both are regular games like any other.
I'm currently waiting for the FSR so I can try it out with GodFall. To be frank, I can't wait to give it a try.

im looking forward to this. I was gonna wipe my windows for full linux but after amd announced it, gotta hold to it until linux got an update on the fsr :)

lasOh well, looks like it's pretty much worse than DLSS 1.0 and nothing like DLSS 2.0 (and never will be - completely different approaches)

wccftech.com/no-amds-fsr-fidelityfx-super-resolution-is-not-a-dlss-alternative-and-here-is-why-you-should-care/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Wccftechcom+%28WCCFtech.com%29

So, not really a DLSS competitor.
It is the feature and what it is supposed to do it competes with not by how good in comparison it is.
I wouldn't judge FSR just yet with what we've seen so far is like drop in the bucket.
Maybe it is worse on NV GTX and WCCFtech evaluate the FSR feature by the GTX 1060 image. The video looks much better though and it uses 6000 series graphics card.
Either way, I would refrain from judgment just yet.

That's just a crystall ball article trying to predict the future based off of two examples.
FSR could be a success or a meh, or most likely something in between. We just don't know yet.

Hairworks is based on DX 11, PhysX is open source, all Gameworks are available in Developer Program. Also Nvidia advertising them as Geforce features why would anyone with AMG GPU enable them and complain about bad performance? If AMD's universal solutions working on both brands but requires additional optimizations for NV there is no point to do it instead of pushing your stuff. Death Stranding and Cyberpunk 2077 have both DLSS and CAS Upscaling.

Dude.
As funny (and stereotypical) is to see misunderstanding of tech from NV lovers.

It is getting embarrassing.

DirectML is an API for accessing GPUs.
It has nothing to do with any concrete ML activity (although it can be used for most of them)

lynx29look at this screenshot. FSR is dead on arrival, look how blurry the ground looks. DLSS 2.0 auto wins if this is all AMD has to showcase....

It's on a GTX 1060, not RX 6000 series. Read it, maybe? And wait for proper independent 3rd party or better yet customers to make comparisons before buying. That is if there is any GPU to buy anyway.
So how can we run NV's DLSS on AMD's cards? Mmm, we can't. Last time I checked GTX doesn't support DLSS at all, only RTX does and it does incur latency penalty, + it took them years to get to a usable state that we see in latest Control and Metro. Original Metro DLSS was abominable and so it was in Control. And only selected few games even support DLSS.

So AMD's version runs on shaders, is free for everyone isn't it. Where as NV's version runs on tensor cores that works only on selected cards in selected situations otherwise the performance penalty is too high to use it.

And don't even get me on the blurry meme that is starting on here. DLSS, which I have and use in latest versions 2.0+, is blurry, there is no other way to say it, no amount of postprocessing sharpening will hide the lack of detail due to not rendering at native resolution. Is it better than plain old stupid bilinear or bicubic upscaling, with 2.0+ yes it finally is.

At least with Metro EE the improvements from what I've seen were not only to DLSS version but also a little to the game itself to run the ray tracing better, still the notoriously problematic areas remained.

There is no other way to make non blurry upscaling in real time. One would have to offline (non real time) upscale with expensive generative methods that add fake detail during upscale.

And I bet this AMD solution is likely to work on consoles too, or some variation of it from each company that orders consoles from AMD.

The more I review checkerboard rendering, I get a feeling super resolution is an enhanced version of this. Supposedly checkerboard rendering exploits pixel fill rate best, hence favoring AMD GPUs. By optimizing for individual titles, they should be able to deal with the common artifacts of this technique. And it sounds like there is no AI inferencing involved, because there is no fast matrix math hardware built into RDNA1/2, so that rules out deep learning reconstruction.

DLSS 2.X may have given up on AI inferencing silently altogether, too because it has resorted to using motion algorithms to place previous pixels in the current frame which works more generically for multiple resolutions and any games that generate the needed buffers. That sounds awfully like CBR, too o_O. So either the tensor cores are re-purposed to aid this new pipeline or they are now sitting idle. Imagine that, if AI upscaling is actually dead...

In the world of graphics rendering tricks, we have come full circle. Gaming was prime at 320x240 and eventually 640x480.

damricHoping my Vega gets some extended life out of this seeing how I can never manage to snag a 6800XT for MSRP.
Don't be so dramatic, Vega cards are nowhere near to being unusable.













But nobody asks the most important question, how good games will looks with DLSS and FSR at the same time?

That is FSR running on a GTX 1060, so it will not look as good, because nVidia has to optimize there drivers for it. Like that is ever going to happen, but still. It will likely look far better on Radeon.
wolfI also wonder about this portion..



and CPU's... is it because some AMD APU's will support it? or is it run (even in part) on the CPU, so only certain ones/above a certain threshold of cores/speed etc will support it?

I am really interested to understand what is going on under the hood.
Intel may support it.

I really hope this works out for AMD... if it ends up being a blurry mess its simply no different than lowering your resolution in windowed mode... :/

AMD has been doing so good lately, don't want to see them embarrass themselves, but I feel like that is with the path we are on. lol

ZoneDymoNvidia on the other hand has a legion of fanboys who will, unpaid, convince the world that any slight problem someone has with a game or there PC is the lack of Nvidia in it and will push....recommend buying Nvidia over anything else.

Times have changed luckely on the AMD vs Intel discussion but that was the same thing not 2 years ago: got a problem? oh you have an AMD cpu? well there is your problem!
Agreed lol the AMD hateboners that everyone has is hilariously stupid. AMD was...how far behind nvidia for a while because of serious financial problems? Now AMD gaining on nVidia REALLY fast, and thats a good thing. RDNA is AMD's Pascal, and they are only just really starting to show what it's made of. I personally am tired of nVidia this, and nVidia that, and nVidia doing shady crap time after time, and welcome the renewed competition from AMD.

I still wonder why AMD hasn't used its intellectual property to make a sample efficient antialiasing filter. They have checkerboard sampling, rotated grid sampling, good compute support and good angle independent AF filter. Couple them together and they could make a driver switch to override the game engine like a postprocess filter. They have all this IP laying around in console platforms. What little diagonal shortcoming of the Nyquist limit can likely be covered by the angle independence of their AF filter and some clever analytical filter before the frame buffer.

If AMD could get this working with APU's to use FSR upscale offloading of a discrete graphics render on the APU that would be a really compelling selling point of their APU's that aren't in stock.
