Xbox Series X|S Get Machine Learning Upscaling with AMD FSR 4.1.2

AMD FSR 4.1.2 is finally making its way to Xbox Series X and Series S, bringing machine learning-powered upscaling to Microsoft’s consoles for the first time. AMD and Microsoft have worked together to optimize the technology for both systems.

Xbox Series X|S gets two AMD FSR 4.1.2 upscaling models

In the official announcement, AMD confirmed that FSR Upscaling 4.1.2 is available through Microsoft’s October 2026 Game Development Kit. Developers already using analytical FSR on Xbox can now move to the machine learning-based alternative.

Interestingly, the console implementation includes two INT8 models. The Full model delivers the standard experience, while the new Lite model is less than half its size and comes with a lower upscaling cost.

Both models work on Xbox Series X and Series S. Developers can switch between them using AMD’s new Xbox GDK sample to compare image quality and GPU performance.

Microsoft has also published performance figures. On Series X, FSR Lite takes 2.75ms at 4K, compared with 3.86ms for Full. On Series S, Lite takes 3.4ms at 1440p, while Full requires 5.2ms.

More importantly, both models have identical upscaler memory requirements. The difference comes down to processing cost and visual quality, rather than memory consumption

The upgrade could also benefit Xbox handhelds

AMD says developers can use the same FSR SDK API across Xbox and Windows. Supported quality modes include Native AA, Quality, Balanced, Performance, and Ultra Performance.

The technology also extends to ROG Xbox Ally handhelds through AMD FSR SDK 2.4. ASUS has already released preview drivers for the ROG Xbox Ally X and X20.

That said, existing Xbox games will not automatically receive the upgrade; developers must integrate FSR 4.1.2 before players can benefit from it.
