AMD has announced that FidelityFX Super Resolution (FSR), its super sampling technology that will increase the performance and image quality of supported games, will be launched on June 22. The company held a presentation at Computex Taipei today with more information about the feature, but it is still not clear how effective it will be.
Supersampling is an important dividing point between AMD’s GPUs and those of competitor Nvidia. DLSS (Deep Learning Super Sampling), Nvidia’s version of the technology, uses neural networks to reconstruct higher quality images from lower resolutions in real time, so that games can run at a smoother frame rate without compromising image quality. Nvidia launched DLSS back in 201
AMD first said they were working on supersampling last year when they announced the RX 6000 series GPUs. The company does not provide too many technical details about the feature yet, but says it will be open source, and that more than ten studios and engines will support it this year.
FSR will support four levels of scaling. In AMD’s own testing, running Godfall on a Radeon RX 6800 XT with epic graphics settings and beam tracking, the performance mode ran at 150 frames per second – a huge increase over the original rendering result of 49 frames per second. The balanced modes, quality and ultra-quality modes gave the results 124 fps, 99 fps and 78 fps, respectively.
Because FSR is open source, it will also run on Nvidia GPUs, including 10 Series models that do not support DLSS. AMD claims a 41 percent increase in performance in quality mode for Godfall on a GTX 1060, for example by increasing the frame rate from 27 fps to 38 fps.
Of course, the company’s own references should never be taken at face value, and the results are not so meaningful without being able to see the effects on the image quality with your own eyes. AMD has not shown much evidence of how FSR actually works in practice – but we will not have too much time to find out, since it will be available in three weeks.
