When AMD launched RDNA2, it promised it will unveil a brand new GPU rendering answer that might match Nvidia’s DLSS. The corporate has now shared some extra particulars on the know-how, with extra approaching June 22.

FidelityFX Tremendous Decision is just not the identical as DLSS. The know-how can be a part of AMD’s GPUOpen program, and AMD is promising assist for a a lot wider vary of GPUs than at the moment assist DLSS 1.zero or 2.zero. At present, AMD expects to assist FSR on RDNA2, RDNA, and Vega GPUs. Whereas it received’t be supported to the identical extent on Nvidia , AMD does plan to supply assist for Pascal, Ampere, and Turing. We don’t know precisely which video games will assist FSR, nevertheless it sounds as if the characteristic requires a minimum of a point of developer collaboration. Intel is reportedly contemplating FSR assist as nicely.

AMD has mentioned that it expects over 10 video games and engines so as to add assist for FSR in 2021, however the one one we all know of is Godfall. Whereas particulars from the corporate are mild to this point, it’s claiming to ship 4 totally different high quality modes (Extremely High quality, High quality, Balanced, and Efficiency).

On paper, the efficiency boosts AMD is claiming are big, with the 6800 XT beginning at 49fps for native 4K and hitting 150fps in Efficiency mode. These features are nothing to sneeze at. However the early knowledge round high quality is just not encouraging. As a lot as I need to stress that that is early knowledge, firms sometimes put their finest foot ahead in these sorts of demos.

I can not hyperlink to the full-size picture that Anandtech posted attributable to limitations in our backend file add measurement, so I’ve zoomed into only one part of it.

We’re zoomed in tightly right here, so nothing goes to look nice. The quantity of blur on the right-hand aspect of the picture is sort of noticeable, nonetheless. This can be attributable to AMD’s resolution to rely strictly on spatial upscaling for FSR, with no info included from movement vectors. This sounds much like how DLSS 1.zero labored for Nvidia. Drawback there may be, DLSS 1.zero for Nvidia didn’t work very nicely.

One other tight zoom, cropped from the underside of the identical picture. There’s a good bit of element being misplaced right here. This isn’t to lose sight of AMD’s bigger level — the corporate is displaying the GTX 1060 operating at 1.41x quicker, and sure, that type of efficiency acquire is clearly going to come back with a high quality tradeoff. It’s simply not clear that FSR can be superior to easily accepting a decrease decision goal within the first place.

A sport operating in 2560×1440 is drawing way more pixels than a sport operating in 1080p. It’s not clear, primarily based on this screenshot, that our hypothetical gamer wouldn’t profit extra from 1080p and barely much less aggressive element settings.

It took Nvidia a short while to get DLSS banged into form, and AMD may have a while to work on FSR as nicely. We’ll see what the corporate unveils a number of weeks from now. The backward compatibility, a minimum of, is a really good contact.
