Xbox Series X and Series S get FSR 4.1.2 support
Microsoft and AMD have added support for the FSR 4.1.2 upscaling technology on Xbox Series X/S consoles. Tools for implementing it are now available to developers with the October 2026 release of the Microsoft GDK.
Two versions of FSR 4
Two versions of the technology have been prepared for consoles: the full-size Full INT8 model and the lightweight Lite INT8. Full INT8 is a neural upscaler adapted for the RDNA 2 graphics architecture in Xbox consoles and uses 8-bit integer calculations. Radeon RX 9000 graphics cards use the Full FP8 model, which relies on floating-point calculations. The Lite model is less than half the size of Full and requires fewer computational resources. However, both versions use the same amount of memory at identical rendering and output resolutions.
Both versions are compatible with Xbox Series X and Series S. Developers can choose the right option based on the capabilities of a particular game and the performance they want to achieve.
Improved image quality
FSR 4.1.2 uses machine-learning algorithms to reconstruct images from lower-resolution frames. This improves image sharpness without requiring every frame to be rendered entirely at the target resolution. Neither Full nor Lite generates additional intermediate frames. That is handled by the separate FSR Frame Generation technology, and its neural version is not included in the announced FSR 4.1.2 support on Xbox.
Microsoft has also published test results for a demo app in the GDK. On Xbox Series X, upscaling to 4K takes 2.75 ms with Lite and 3.86 ms with Full. On Xbox Series S, at an output resolution of 1440p, the figures are 3.4 and 5.2 ms, respectively. These are the GPU upscaling times, not the total time required to render a frame.
When will it arrive in games?
For now, FSR 4.1.2 is available to developers, not all Xbox owners. Studios will need to add support for the technology to their projects themselves. So don’t expect image quality to improve automatically in every game that has already been released.
The update also expands the capabilities of ROG Xbox Ally handhelds through AMD FSR SDK 2.4. An ASUS preview driver is available for the ROG Xbox Ally X, enabling FSR 4.1.2 in DirectX 12 games that support FSR 3.1 or later. Support for the base ROG Xbox Ally will be added to the driver later.
