What is AMD FSR? FidelityFX super resolution explained

AMD Fidelity FX Super Resolution (FSR) is a rendering technology designed to increase the frame rate in games and achieve high-quality, high-resolution games.It is also a competitor of NVIDIA DLSS, Although the two are very different in function. The working principle of FSR is to render the frame at a lower resolution, and then use the open-source spatial enlargement algorithm to make the game appear to be running at a higher resolution. DLSS uses AI algorithms to achieve similar results, but it only works on Nvidia’s RTX GPUs, some of which Best graphics card Now. In contrast, FSR can run on almost any GPU-for example, we have confirmed that it can even run on Intel integrated graphics.

AMD does not directly promote FSR as a competitor to DLSS, mainly because it believes that FSR can be applied to a wider range of games.Although FSR can definitely help high-performance games and games with a wide range of effects, such as Ray tracing, It can also be used as a general algorithm to simply improve performance, even in games that are already running well.This may prove useful for high refresh rate 1440p monitors, some of which The best gaming monitor, But it can also help smooth the frame rate and Gaming laptop.

For example, the game may not run particularly well in the native environment 4K Rendering. FSR allows users to render anywhere 1440p (FSR Super Quality) to 1080p Resolution (FSR performance), which will make it easier to reach higher frame rates, and there are two other options. Then the generated image is enlarged to the target resolution to obtain higher performance than 4K and clearer details than 1080p. Then apply UI elements and text to the final output.

AMD claims that FSR provides improvements over other types of spatial amplification methods (such as bilinear amplification). In addition to providing different levels of performance and supporting different games and applications, the biggest difference between the two is that AMD FSR has nothing to do with the GPU, so it can be used with AMD and Nvidia and Intel graphics cards. In contrast, DLSS only applies to Nvidia GPUs.

Because PlayStation 5 (PS5) uses AMD RDNA 2 based GPU, it also supports FSR. The first PS5 game to provide FSR support is arcade. This Xbox X series/S also uses RDNA 2 based GPUs, which will be Get FSR support as well as. In the long run, this is a key advantage of FSR, not only supporting PCs, but also game consoles, and possibly even smartphone hardware.

AMD FSR has four different modes: Ultra Quality, Quality, Balanced and Performance. Using the highest level of performance mode shown in the image above, AMD claims that you will see an average performance increase of 2.4 times at 4K resolution. But more upgrades will lead to more visual artifacts. And, just like the highest performance of Nvidia DLSS, you can expect obvious artifacts in FSR performance mode.
