AMD and Microsoft have made FSR Upscaling 4.1.2 available to game developers on Xbox Series X and Series S through the October 2026 Game Development Kit (GDK).
What happened?
This is the first time AMD's machine-learning-based upscaling technology reaches Xbox Series consoles. FSR 4.1.2 includes two INT8 models: Full (standard implementation) and Lite (less than half the size and lower GPU cost). Both work on Series X and Series S, letting studios choose the quality-versus-performance balance.
According to GDK sample measurements, on Series X the Lite model costs about 1.29 ms at 1440p and 2.75 ms at 4K; Full costs 1.95 ms at 1440p and 3.86 ms at 4K. On Series S the costs are higher at equivalent resolutions. The implementation uses the same FSR SDK as PC and was optimized in partnership with the Xbox team for the consoles' RDNA 2 GPUs.
Why this matters
Until now Xbox consoles relied on older analytical FSR versions. AI upscaling can improve perceived image quality and help extract more performance from 2020 hardware. It joins Sony's QSSR on base PS5 and DLSS options on Switch 2, raising the upscaling standard across current platforms. Existing games will only get the feature if developers update them.
Official sources include AMD GPUOpen blog and Microsoft's developer announcement. Immediate availability is for registered studios; player impact depends on developer adoption.
What changes in practice
Xbox Series developers now have a modern ML upscaling tool to improve visuals and performance, especially useful on Series S. Players can expect future patches in titles that adopt it. It is not an automatic update for all games.
