AMD has officially introduced FidelityFX Super Resolution 2.0 (FSR) image scaling technology. Unlike FSR 1.0, which relies on spatial scaling algorithms, FSR 2.0 uses temporal scaling algorithms. The manufacturer says that FSR 2.0 will be available in the second quarter of this year.
Keep in mind that spatial scaling only uses data from one captured frame of the game. Temporal scaling uses data from the current frame as well as data from the previous game frame. By the way, NVIDIA DLSS 1.0 technology also used spatial scaling, and with the transition to DLSS 2.0, it began to use temporal scaling.
According to AMD, FSR 2.0 is capable of delivering higher image quality than when rendered at native screen resolution. The technology will also include various anti-aliasing algorithms that will significantly improve image quality compared to FSR 1.0.
Unlike the same NVIDIA DLSS and Intel XeSS scaling technologies, the new AMD FSR 2.0 does not rely on machine learning algorithms. This means that AMD technology does not require special tensor cores or matrix engines (XMX) in the graphics chip. Support for FSR 2.0 is provided by individual models of graphics accelerators, and this does not only apply to Radeon cards – competing solutions can also work with this technology.
“Like FSR 1.0, FSR 2.0 scaling technology does not use any machine learning (ML) scaling algorithms. While ML is an excellent tool for a number of specific tasks, the technology is not required to provide good scaling performance. Therefore, FSR 2.0 does not require dedicated ML hardware, so many more games can benefit from it. FSR 2.0 will work across products and platforms, and as with FSR 1.0, this includes some competitor graphics cards.”explains AMD.
The company has provided several screenshots demonstrating the FSR 2.0 scaling technology in Deathloop in the Performance and Quality setting modes. The result is compared with images in native 4K resolution, as well as the operation of FSR 1.0 technology. The following images can be viewed in full size.
It should be noted that image scaling technologies mostly show the best results on static images. That’s why AMD also posted a video demonstrating FSR 2.0 in the same game.
Below in the gallery you can see examples of the operation of the FSR 2.0 technology in the mode “Quality” on 300x frame magnification.
AMD also confirmed that the FSR 2.0 image scaling technology will remain the open standard. The technology source code is published for game developers in the GPUOpen repository.
