AMD announced the launch of FidelityFX Super Resolution, or FSR, technology on June 22. FSR is a superior sampling technology that enhances performance and picture quality in supported games.
The company gave a presentation at Computex 2021 with more information on the feature. This is although it is still not clear how effective they are. Ultra sampling is a major differentiator between AMD GPUs and competitor NVIDIA's.
DLSS, the NVIDIA version of the technology, uses neural networks to reconstruct images at higher-than-lower resolution in real-time, allowing games to run at smoother frame rates without compromising image quality.
NVIDIA launched DLSS in 2018 with the RTX 20 series, and it's been increasing performance and support ever since.
More than 50 games now work with DLSS, and Nvidia has announced that Red Dead Redemption 2 and Rainbow Six Siege are getting this feature.
AMD responds to Nvidia
AMD said it was working on ultra sampling last year when it announced the RX 6000 GPUs. The company doesn't provide many technical details about the feature yet. But it says it will be open source and that more than a dozen studios and engines are supporting it this year.
FSR supports four levels of scaling. And in AMD's own test, I ran Godfall via the Radeon RX 6800 XT with epic graphics settings and ray tracing.
Performance mode ran at 150 fps, a massive increase from the original 49 fps. The Balanced Quality and Ultra Quality modes went for results of 124 fps, 99 fps, and 78 fps, respectively.
Given that the FSR is open source, it also runs across NVIDIA GPUs, including the 10 Series models that do not support DLSS. AMD points to a 41 percent performance increase in Godfall's quality mode via the GTX 1060 card, for example, and an increase in frame rate from 27 fps to 38 fps. And AMD has not shown much evidence of how FSR actually works in practice. But it will be available in three.
