AMD is about to explain more about FidelityFX Super Resolution (FSR) 2.0 technology at GDC, but at present, the new features of FSR 2.0 are also generally introduced in GPUOpen, which is simply to import “Temporal Data” and replace “Anti-Aliasing (TAA)” “.
To put it simply, FSR 2.0 will require the game to provide Depth Buffer, Motion Vector Buffer, Color Buffer and other current screen data, and hand it over to the FSR 2.0 function while referring to the Outout Buffer of the previous screen for processing, so as to obtain better performance and proximity The high quality of native rendering; at the same time, FSR 2.0 will replace the previous TAA function of the game.
FSR 2.0 will replace the TAA position of the original drawing pipeline. In the past, Posts that needed to deal with Anti-Aliased and special effects need to be pre-upscaled first, and then handed over to FSR 2.0 for processing in Linear Color Space, and then handed over to Post-upscale to display the in the screen.
AMD mentioned that if the game itself already supports the DLSS 2.X version, it will take less than 3 days to import the FSR 2.0 function, and games such as UE4/UE5 can also be added through Plugin. As for the game support Decoupled separation rendering, display resolution If there is a TAA processing function, the addition time is relatively short, but the game does not support separate rendering, display resolution and motion vector, it may take 4 weeks to add the FSR 2.0 function.
FSR 2.0 also provides 4 modes. Each mode mainly corresponds to different input resolution and output resolution. In Quality mode, the magnification is only 2.25x, which can maintain close to the original image quality and good performance improvement, while in Performance mode It is a magnification of nearly 4x, and the relative picture quality will be slightly insufficient.
The first game that currently supports FSR 2.0 is “DEATHLOOP”, and “Forspoken” will also support this feature in the future, and FSR 2.0 is expected to be opened in the game in October 2022, whether it is AMD, NVIDIA should say any PC player All can feel the performance improvement brought by FSR 2.0.
