AMD has officially brought FSR Upscaling 4.1.2 to Xbox Series X and Xbox Series S, introducing machine learning-based image upscaling to Microsoft’s consoles for the first time. The technology is available to game developers through the October 2026 Xbox Game Development Kit (GDK), providing new options for improving visual quality while managing GPU performance.
The release was confirmed in a November 4 announcement on AMD’s GPUOpen developer website. Developed in collaboration with Microsoft’s Xbox team, FSR 4.1.2 replaces the purely analytical approach used by earlier FidelityFX Super Resolution implementations with a machine learning-based alternative. Developers can now integrate the technology into Xbox games using tools shared with the Windows PC version.
Unlike a system-wide console update, the release does not automatically enable FSR 4.1.2 in existing Xbox games. Individual developers must implement the technology, meaning improvements will depend on which titles adopt it and how their rendering systems are configured.
AMD FSR 4.1.2 introduces two upscaling models for Xbox Series X|S: Full INT8 and Lite INT8. Both are compatible with Microsoft’s two current-generation consoles, allowing developers to select the implementation that best suits their game’s graphical requirements.
The Full model provides the standard machine learning upscaling implementation, while the Lite version is designed to reduce processing overhead. According to AMD, the Lite model is less than half the size of the Full model and has a lower upscaling cost.
Despite that difference, AMD says both models have the same upscaler memory requirements because memory consumption depends on rendering and display resolutions rather than model size. Developers therefore choose between them primarily based on the balance of image quality and GPU performance.
This flexibility could be particularly useful for Xbox Series S games, where developers often have tighter graphics performance budgets. However, AMD has not established a universal performance improvement for games adopting either model, and the results will depend on individual implementations.
To assist developers, AMD has released an FSR GDK sample that allows switching between the Full and Lite models during runtime. This lets teams compare image quality and processing costs within the same scene rather than evaluating each implementation separately.
The sample supports Xbox Series X|S and Windows desktop builds, with accompanying documentation containing memory and performance figures for both console models.
Integration also follows the existing AMD FSR SDK API used on Windows. Registered Xbox developers can access AMD-signed console binaries through Microsoft’s GDK and use the same API headers as their PC counterparts.
The upscaler accepts familiar rendering inputs, including jittered color data, depth information and motion vectors. Reactive masks and transparency and composition masks remain optional.
Developers can also offer the same five quality presets available on PC: Native AA, Quality, Balanced, Performance and Ultra Performance. AMD recommends using consistent preset names and scaling ratios across supported games.
The Xbox announcement also extends AMD’s wider rollout of FSR SDK 2.4, which adds support for Radeon RX 6000 GPUs, selected Ryzen processors and Vulkan upscaling. The shared development framework is intended to make the technology easier to deploy across consoles, desktop PCs and portable gaming hardware.
AMD has confirmed that FSR Upscaling 4.1.2 also supports the ROG Xbox Ally, ROG Xbox Ally X and ROG Xbox Ally X20 through the standard Windows FSR SDK. The latest SDK includes an efficient INT8 model for compatible Ryzen AI Z2 Extreme and Ryzen Z2 A processors.
For developers testing the technology on handhelds, ASUS has made a preview graphics driver available for the ROG Xbox Ally X and ROG Xbox Ally X20. The driver enables upgrades for DirectX 12 games using FSR 3.1 or newer, while support for the standard ROG Xbox Ally is expected in a subsequent update.
AMD recommends native integration through the latest FSR SDK, particularly for developers targeting Vulkan, where native SDK integration is required for FSR Upscaling 4.1.2.
For Xbox players, the immediate change is the availability of a new rendering option for developers rather than a guaranteed improvement across the existing game library. Machine learning-based upscaling can help reconstruct higher-resolution images from lower-resolution rendering inputs, potentially allowing developers to balance visual fidelity and performance more effectively.
AMD has not announced a confirmed list of Xbox games implementing FSR 4.1.2 in conjunction with this release. Its arrival in the October 2026 GDK establishes the technical foundation, with actual game support dependent on future developer updates and integrations.
