General Key points
- 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.
- Unlike DLSS, it does not require any dedicated hardware (Nvidia RTX GPUs) and does not utilise machine learning either. The upscale algorithm is based off modified Lanczos algorithm.
- It can be applied on any application as a post-processing filter. On Windows, with Magpie [1] or Lossless Scaling [2], and on Linux, it can applied either with Wine or on any Vulkan game with Proton[3].
- 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.[4]

FidelityFX Super Resolution 2.0
Key points
- AMD FidelityFX Super Resolution 2.0 (FSR 2) is an open-source temporal upscaler.
- 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 2.1/2.2. 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.
- This version has additional enhancements catered towards ghosting on fast moving objects.[7]
