AMD FidelityFX Super Resolution 3 (FSR3) is the latest version of AMD’s upscaling technology that aims to boost the performance and image quality of supported games. FSR3 is AMD’s answer to Nvidia’s DLSS 3 and Intel’s XeSS, which use machine learning to generate high-resolution images from lower-resolution ones. In this article, we will explain what is AMDs FSR3? how it works, what games and graphics cards support it, and when it is coming out.
What is FSR3?
FSR3 is a combination of three technologies: super resolution upscaling, frame generation, and latency reduction. Super resolution upscaling is the process of rendering a game at a lower resolution and then using an algorithm to upscale it to a higher resolution, while preserving or enhancing the image quality. Frame generation is the process of creating additional frames between the original ones, using motion vector data and optical flow technology, to increase the framerate and smoothness of the game. Latency reduction is the process of minimizing the input lag between the user’s actions and the game’s response, using techniques such as anti-aliasing and sharpening.
How does FSR3 work?
FSR3 works by applying different levels of upscaling and frame generation to the game, depending on the user’s preference and hardware capability. The user can choose from four quality modes: Native AA, Quality, Balanced, and Performance. Native AA mode renders the game at native resolution with anti-aliasing applied, without any upscaling or frame generation. Quality mode renders the game at 77% of native resolution with upscaling and frame generation applied at 1.5x rate. Balanced mode renders the game at 67% of native resolution with upscaling and frame generation applied at 2x rate. Performance mode renders the game at 50% of native resolution with upscaling and frame generation applied at 4x rate.
The upscaling algorithm used in FSR3 is based on FSR2, which was released in 2021 and updated in 2022. FSR2 uses a spatial adaptive sharpening filter to enhance the details and contrast of the upscaled image, while reducing noise and artifacts. FSR3 improves on FSR2 by integrating it with the new frame generation technology, which uses an enhanced version of AMD Fluid Motion Frames (AFMF) optical flow technology to generate additional frames. AFMF analyzes the motion vectors of the original frames and interpolates new frames between them, using a temporal feedback loop to reduce ghosting and blurring effects.
The latency reduction technology used in FSR3 is based on AMD Anti-Lag+, which was introduced in 2022 as an extension of AMD Anti-Lag. Anti-Lag reduces the input lag by synchronizing the CPU and GPU workloads, while Anti-Lag+ further reduces it by applying sharpening and anti-aliasing filters to the final image.
What games and graphics cards support FSR3?
FSR3 is an open source and hardware-agnostic technology that can work on any DirectX 11 or DirectX 12 game that supports motion vector data. However, not all games have implemented FSR3 yet, as it requires some integration work from the developers. AMD has announced that two games will be the first to support FSR3: Forspoken by Square Enix and Immortals of Aveum by Ascendant Studios and Electronic Arts. Both games are expected to add FSR3 support in early fall 2023.
As for graphics cards, FSR3 supports a wide range of GPUs from AMD, Nvidia, and Intel. AMD has confirmed that the following graphics cards are compatible with FSR3:
- Radeon RX 5000, 6000, and 7000 series
- Intel Arc GPUs
- Nvidia RTX 20, 30, and 40 series
AMD also says that FSR3 will work on unspecified game consoles, likely the PlayStation 5 and Xbox Series X/S.
When is FSR3 coming out?
AMD has not given a specific release date for FSR3 yet, but it has said that it will be available in early fall 2023. The first games to support FSR3 will be Forspoken and Immortals of Aveum, followed by more titles in the future. AMD also plans to release an update for its Radeon Software Adrenalin Edition driver that will enable FSR3 for all compatible games.
AMD FSR3 is an exciting new technology that promises to deliver massive performance gains and image quality improvements for supported games. AMD hopes that FSR3 will become a widely adopted standard for upscaling and frame generation in the gaming industry and with their opensource and hardware agnostic approach it is highly likely that might be the case .
