AMD FidelityFX Super Resolution: What It Is, How to Use It

After loads of anticipation, AMD finally pulled the curtain back on FidelityFX Super Resolution at Computex 2021. Its upscaling function is positioned to problem Nvidia’s deep learning super sampling (DLSS), bettering body charges by over 200% in some video games at 4K with ray tracing turned on.

Super Resolution is a giant step for AMD, providing the RX 6000 graphics cards a much-needed increase with ray tracing and giving players with older playing cards a serving to hand at a time when buying new GPUs is so difficult. That mentioned, Super Resolution isn’t only a copy of DLSS. In addition to supporting {hardware} from AMD and Nvidia, Super Resolution makes use of a special upscaling approach that would dethrone DLSS because the go-to upscaling choice.

Now that FidelityFX Super Resolution is broadly accessible, right here’s all the things it’s worthwhile to find out about what FSR is and the best way to use it.

What is AMD FidelityFX Super Resolution?

FidelityFX Super Resolution (FSR) is AMD’s reply to Nvidia’s Deep Learning Super Sampling (DLSS). Like DLSS, FSR is an image-upscaling function that makes a sport appear like it’s rendering at the next decision than it truly is. So, the engine could render the sport at 1080p, after which FSR steps in to fill within the lacking pixels to make it appear like a 1440p output.

FSR isn’t only a copy of DLSS, although. Nvidia’s tech works by coaching a synthetic intelligence (A.I.) mannequin with high-quality scans offline (say, a 16K nonetheless body). DLSS can then fill within the additional info in a body utilizing the A.I. mannequin. FSR works just a little otherwise, utilizing no machine studying, and it doesn’t require any per-game coaching. Developers can implement it independently of AMD, with no specialised drivers or {hardware} required.

Also in contrast to DLSS, AMD is taking an open strategy to FSR. The total FidelityFX suite works throughout many generations of GPUs from AMD and Nvidia, together with FSR. At launch, the function is supported on RX 6000, RX 5000, RX 500, and 400 GPUs, in addition to Nvidia GTX 10-series and 16-series and RTX 2000 and 3000 playing cards. Ryzen processors with Radeon graphics are supported, too.

In addition, the supply code is available for free to developers on AMD’s GPUOpen platform, and it’s accessible by way of the Unreal Engine 4 and Unity sport engines. Basically, any developer, no matter their price range or connections, can get FSR working of their video games.

FSR affords 4 high quality modes: Ultra Quality, Quality, Balanced, and Performance. Ultra high quality boosts body charges whereas retaining as a lot element as potential. Further down, every efficiency mode affords the next body charge at the price of picture high quality by rendering at decrease resolutions and utilizing extra excessive sharpening to compensate.

How does FidelityFX Super Resolution work?

The AMD FidelityFX Super Resolution rendering pipeline.

FidelityFX Super Resolution is a “shadow-based” upscaling approach that takes place towards the top of the rendering pipeline. It takes a picture rendered at a decrease decision than the native decision set by the gamer and performs two passes to enhance its visible high quality so it’s extra akin to the native decision. The first is an edge-reconstruction upscaling algorithm, which makes an attempt to recreate the picture as if it have been the next decision than it’s. A secondary sharpening cross then provides additional readability to the picture.

The enter decision for the algorithm to work with is determined by the FSR high quality mode chosen by the consumer. For a 4K output, the place native is 3840 x 2160, FSR Ultra Quality would render at 2954 x 1662. It makes use of 2560 x 1440 for Quality mode, 2259 x 1270 for Balanced mode, and 1920 x 1080 for Performance mode.

FidelityFX Super Resolution input resolutions at different quality modes.

In lower-quality modes, builders could decide to make use of extra aggressive sharpening to compensate for the decrease enter decision. This may end up in the looks of sharpening artifacts, as we noted in our testing.

Like DLSS, the approach is simplest when the upscaling algorithm has extra info to work with at larger native resolutions. However, FSR can work effectively at 1080p, and even decrease resolutions, probably enabling a few of these older GPUs it helps to play video games that might in any other case have been unimaginable to get working.

When can you employ FidelityFX Super Resolution?

AMD Radeon RX 6000.

AMD debuted FSR throughout its Computex 2021 keynote and adopted by way of with a basic launch on June 22. All it’s worthwhile to reap the benefits of it is among the many supporting GPUs, the latest Radeon driver, and one of many video games that has an FSR setting.

Currently, the function is just accessible on PC, although we anticipate AMD to introduce it to the RDNA 2-based PlayStation 5 in some unspecified time in the future. Shortly after Microsoft’s Windows 11 announcement, the corporate introduced that FSR is coming to Xbox, too. Developers can entry a preview model of FSR within the Microsoft Game Development Kit (GDK) to be used on Windows, Xbox Series X, and even Xbox One.

When it involves consoles, FSR will grow to be an essential a part of the sport growth pipeline. Console video games are already stretching the efficiency limits of their machines, so a robust upscaling approach will grow to be important because the consoles start to age. Hopefully, which means huge adoption, which is nice information for PC players, too.

What video games help FidelityFX Super Resolution?

The present listing of FidelityFX Super Resolution video games contains:

  • Anno 1800
  • Evil Genius 2
  • Godfall
  • Kingshunt
  • Terminator Resistance
  • The Riftbreaker
  • 22 Racing Series
  • Necromunda: Hired Gun
  • Arcadeggedon 

More video games are coming quickly, although, a few of which we’ve a launch window for. Though they don’t have any agency launch date, upcoming confirmed FSR video games embody:

  • Asterigos
  • Baldur’s Gate III
  • DOTA 2
  • Edge of Eternity (July 2021)
  • FarCry 6
  • Farming Simulator 22
  • Forspoken
  • Myst
  • Resident Evil: Village (July 2021)
  • Swordsman Remake
  • Vampire The Masquerade: Bloodhunt

AMD has reportedly partnered with over 40 main studios to undertake FSR sooner or later, together with EA Frostbite, Obsidian Entertainment, Focus Home Interactive, Capcom, Larian Studios, and Turtle Rock, amongst many others.

If you wish to see FSR in your favourite sport, you possibly can request it by way of the AMD FSR wishlist.

A DLSS killer?

Between DLSS and FSR, there are already stark variations in high quality and help. DLSS 2.0 is by far the extra spectacular upscaling know-how, delivering wonderful efficiency enhancement with restricted visible artifacts. It additionally has a variety of supporting video games, with over 55 current titles supporting DLSS 1.0 or 2.0 in some guise and an extra 10 deliberate within the coming 12 months.

DLSS is restricted to Nvidia’s RTX graphics playing cards, although, that are extremely costly and in brief provide. FSR is supported by nearly each graphics card launched within the final 5 years, and its upscaling is each efficient and has restricted visible affect at higher-quality settings. That could possibly be an enormous game-changer for these utilizing older or weaker graphics playing cards and provides AMD followers with high-end GPUs improved efficiency when utilizing ray tracing.

The solely drawback is the restricted video games it’s accessible on proper now. With its extra open stance and wider {hardware} help base, nonetheless, that appears prone to change. Consider too that FSR is coming to house consoles, and it has all of the potential on this planet to be the extra common — if not fairly as efficient — upscaling know-how.
