AMD FidelityFX Super Resolution: what it is and how it works

After the official announcement during the conference held at Computex 2021, AMD is ready to launch a new feature for AMD Radeon RX 6000 series GPUs and more. IS FidelityFX Super Resolution, a solution that challenges Nvidia’s DLSS in combining 4K resolutions and ray tracing. FidelityFX Super Resolution could be a major step forward for AMD and, since supports both proprietary and third-party hardware, could dethrone DLSS as an upscaling solution. We have gathered all the information you need about AMD Fidelity FX Super Resolution in this article, which we will update whenever there is news.

What is AMD FidelityFX Super Resolution?

AMD FidelityFX Super Resolution, abbreviated to FSR, is the risposta al Deep Learning Super Sampling introduced by Nvidia on Nvidia GeForce RTX 20 series and later GPUs. AMD FidelityFX Super Resolution is an image reconstruction tool, which makes a game appear as if it is being rendered at a higher resolution than it actually is. In this way the graphics engine can render the game at 1080p, and then let FidelityFX Super Resolution intervene to “fill in” the missing pixels and make the output look like 1440p.

The approach adopted by AMD con FidelityFX Super Resolution It’s open. The function will be available for numerous GPUs both AMD and Nvidia: AMD Radeon RX 6000, 5000 and 500 series GPUs and Nvidia GeForce GTX 10 series and newer GPUs will support at launch. Ryzen APUs with Radeon integrated graphics will also support FidelityFX Super Resolution. AMD FidelityFX Super Resolution will have to be implemented in games by developers, who will have full freedom on the final product and its outcomes.

How does FidelityFX Super Resolution work?

Fidelity Super Resolution is not a copy of Nvidia’s DLSS. Nvidia’s technology works by training artificial intelligence with high-quality offline scans (the same principle later adopted by Nvidia GANverse3D). With FidelityFX Super Resolution AMD is going in a completely different direction. Scott Herkelman, vice president of graphics at AMD, explained in a PCWorld brodcast on YouTube that “you don’t need machine learning to do that” and that AMD is “evaluating many different ways” to achieve FidelityFX Super Resolution outcomes.

In 2019 AMD filed a patent, called “Gaming Super Resolution” and made public on May 20, 2021, which explains how FidelityFX Super Resolution works. The paper reveals that AMD uses a hybrid supersampling approach, which combines linear and non-linear upscaling technology to achieve the most detailed picture possible. The patent explains that linear techniques across a neural network do not include nonlinear information, which “typically results in blurry and / or corrupted images.” To solve this problem, AMD has chosen to use a hybrid solution and combine both methods. “The combination of linear and non-linear upscaling – reports the text – facilitates both the preservation of color and large-scale image characteristics from linear upscaling, and the preservation of the finer characteristics of the image from non-linear upscaling. .

With FidelityFX Super Resolution there are, therefore, two paths for the reconstructed image. The original low-resolution image goes through a series of linear upscaling and a series of non-linear upscaling at the same time, which gather different information. FidelityFX Super Resolution then combines the low resolution images to create a pixel grid, then applies the highest resolution image on each of them. After cleaning the frames, you will have the reconstructed image. We know that FidelityFX Super Resolution delivers four levels of quality, called “Ultra”, “Quality”, “Balanced” and “Performance”. Ultra mode, according to Computex 2021, can increase the framerate by 50% while maintaining as much detail as possible. The other modes offer an even higher frame rate, while reducing the image quality.


Which products will support FidelityFX Super Resolution?

The patent also confirmed that AMD FidelityFX Super Resolution it will work on a large number of devices. The document states that it may work on “a computer, gaming device, portable device, set top box, television, cell phone or tablet.” Right now, AMD would appear ready to support over 100 GPUs and CPUs, including Mobile GPUs and some APUs. According to the reports, we assume that AMD FidelityFX Super Resolution can support more CPUs, GPUs and APUs in the future. Like the rest of the AMD suite of features, it will be possible to access FidelityFX settings directly in-game.

When will FidelityFX Super Resolution be released?

AMD unveiled FidelityFX Super Resolution during the Computex 2021 keynote. The release date is set for Tuesday 22nd June. The feature will initially only be available on PC, but we expect it to AMD may also introduce it on next-generation consoles based on RDNA2 GPUs – both Xbox X | S Series and PlayStation 5. The eventual distribution of FidelityFX on consoles could affect the development cycle of the games and the life of the machines. While both consoles are great and not yet fully exploited today, in the future developers will necessarily have to resort to image reconstruction technology to get the best look in games, perhaps even activating ray tracing – or leave it to players. possibility to choose between aesthetics and performance. Since Nvidia’s DLSS technology is exclusive to its GPUs, it will not be able to be adopted by any console with the exception of a possible successor to the Nintendo Switch.


What games will support FidelityFX Super Resolution at launch?

During the keynote at Computex 2021, AMD showed FidelityFX Super Resolution with Godfall. Counterplay Games’ action RPG featured a 59% performance increase at 4K and with active ray tracing by applying the Ultra mode of FidelityFX. AMD has announced that a first group of games will support FidelityFX with an update right from June 22. According to the company, they are at least 10 software houses that will adopt FidelityFX Super Resolution by the end of 2021.

AMD has also set up a survey to ask users to indicate which games they would like FidelityFX Super Resolution to be implemented on. While AMD will work with developers to anticipate FidelityFX in their games early on, they will be the ones to choose if, when and how to implement this feature. Currently more than 40 titles support at least one FidelityFX feature, usually Contrast Adaptive Sharpening. We expect the list of titles supporting FidelityFX Super Resolution to grow rapidly in the coming months.

The perspectives of FidelityFX Super Resolution

Although AMD FidelityFX Super Resolution and DLSS exhibit very close performance, there is a possibility that AMD achieves better results through cross-platform and open development. Developers should be pushed to implement FidelityFX in their games thanks to support on a large number of hardware. Also, FidelityFX Super Resolution could make buying an AMD GPU more attractive. Nvidia currently holds the record for ray tracing performance thanks to DLSS. If, thanks to FidelityFX Super Resolution, AMD Radeon RX 6000 series GPUs emulate the performance of DLSS, AMD GPUs will once again be a solid option to play the latest AAA releases with maximum settings active. We will monitor the situation with our analysis and, in the case of major performance improvements, we will update our guide to the best video cards to better reflect any changes.
