FidelityFX Super Resolution
FidelityFX Super Resolution at Wikipedia

General key points

AMD FidelityFX Super Resolution is used to upsample an input image into a higher resolution.
Open source, can be used with most modern GPUs, including but not limited to AMD, Intel and NVIDIA cards.

FidelityFX Super Resolution 1.0

Key points

AMD FidelityFX Super Resolution 1.0 (FSR) is an open-source spatial upscaler, released on 22nd June 2021.[1]
Unlike DLSS, it does not require any dedicated hardware (Nvidia RTX GPUs) and does not utilise machine learning either.
It applies a directionally and anisotropically adaptive radial Lanczos algorithm.[2]
It can be applied on any application as a post-processing filter. On Windows, with Magpie[3] or Lossless Scaling, and on Linux, it can applied either with Wine or on any Vulkan game with Proton.[4]
Used in Steam Deck to upscale any game.
Native game implementation produce much higher fidelity image as the upscale is applied before any UI elements and post-processing effects are applied. Third-party implementation such as Steam Deck's apply the upscaling at the very end of the rendering pipeline, blurring UI and producing significantly much worse image.
Generally worse in terms of visual quality due to being a spatial upscaler in comparison to DLSS and FSR 2, which are temporal upscalers and replace the game's anti-aliasing.[5]

FidelityFX Super Resolution 2.0

Key points

AMD FidelityFX Super Resolution 2.0 (FSR 2) is an open-source temporal upscaler, released first for Deathloop on 12th May 2022, and then open sourced on 22nd June 2022.
Produced image quality is perceivably almost as good as DLSS, without requiring dedicated hardware (NVidia RTX) or machine learning hardware.
Similar to DLSS, it replaces the game's anti-aliasing.
AMD reported that implementing FSR 2 in games already supporting any temporal based upscaling technology (such as DLSS) could be achieved with relative ease by developers.
There are unofficial modifications available for games which allow for replacing DLSS implementation with FSR 2.
Games that may expose the FSR 2.0 DLL can be swapped for FSR 2.1. Do note that this may not work with each game, or may not yield any benefits due to changes in the API.

FidelityFX Super Resolution 2.1

First major improvement to FSR 2.0, dubbed FSR 2.1.
Alleviating ghosting issues on particles with unmatching underlying pixel colors.
Overall color range and temporal stability of the upscaled image.
Performance improvements across all presets.

FidelityFX Super Resolution 2.2

Second major improvement to FSR 2.0, dubbed FSR 2.2.
Additional enhancements catered towards ghosting on fast moving objects, referred to as "High Velocity Ghosting".[6]
Improved temporal stability, which should result in a more stable, less flickering and "fizzing" artefacts.
