On an average, an increase of 2–2.5 times can be observed.Īpart from improvising performances on GPUs, AMD is now moving towards the console lineups. The picture quality was affected, but the higher frame rate was easily achieved.ĪMD FSR has been seen significantly increasing the picture quality and increasing the performance in different games that support FSR. Unlike DLSS, FSR does not require any additional specialized graphics hardware and thus is not computation heavy.Īnother benefit that FSR offers over its competitors is that, while its competitors fail to accommodate lower frame rates at a higher level, FSR was able to do the task successfully.
MODEĪMD FSR is GPU-agnostic, which means that it can work with GPUs from different brands, unlike Nvidia DLSS, which can only be used with Nvidia GPUs.ĪMD FSR is an open-source software, which will result in quicker, easier, and more rapid adaptability. I am also attaching a comparison between input and output resolutions for different modes for your better understanding. These performance and quality modes will also be affected by the choice of our GPU. It offers a scaling factor of 2x in each dimension and 4x area scaling, with a 50% screen resolution. Performance mode significantly affects the image quality and should only be used if additional performance is necessary. It offers a scaling factor of 1.3x in each dimension and 1.69x area scaling, with a 59% screen resolution. In balanced mode, high-quality images are produced with quality approximately similar to the native rendering, with a major performance gain achieved compared to the native. It offers a scaling factor of 1.5x in each dimension and 2.25x area scaling, with a 67% screen resolution. The Quality mode of AMD FSR produces high-quality images with similar quality as native rendering, which also gives a sizeable performance gain. It offers a scaling factor of 1.3x in each dimension and 1.69x area scaling, with a 77% screen resolution. This mode produces the highest quality of rendering, which is virtually indistinguishable from the original rendering.

In the end, the results will vary depending upon a few factors, such as the game that is being played, which mode I am using, or what graphics card I am using.Īlthough current AMD FidelityFX Super Resolution uses the spatial upscaling technique, this will be changed in the upcoming update of AMD FSR 2.0, which will be swapping out spatial upscaling with temporal upscaling instead.Īrbitrary scaling is usually used for Dynamic Resolution Scaling, where source resolution is governed by a defined performance budget to achieve a minimum frame rate.ĪMD FSR offers four quality modes, which are: ultra-quality, quality, balanced, and performance. Upscaling and sharpening depend on the quality level that is to be achieved. FSR also includes utility methods for color space conversions, dithering, and tone mapping to make it easier to integrate it into today’s game rendering pipelines. RCAS (Robust Contrast-Adaptive Sharpening) is a sharpening technique that extracts pixel detail in an upscaled image. The weights to apply to the reconstructed pixels at display resolution are determined by the concentration of the gradient reversals. The major component of the algorithm detects gradient reversals, essentially looking at how surrounding gradients differ from a group of input pixels during this pass. After that, the game’s HUD is rendered.ĮASU (Edge-Adaptive Spatial Upsampling) is an upscaling pass that additionally includes edge reconstruction. Once the frame has gone through anti-aliasing and tone mapping, AMD FSR carries out an upscaling pass, and a sharpening pass before film grain and other similar effects are applied. But everything has its pros and cons, and while efficiency and lower system requirements tend to be the pros for AMD FSR, lower image quality, in comparison to temporal upscalers such as those found in Unreal Engine or Nvidia DLSS, are the disadvantage of AMD FSR.
