AMD adds FSR 4.1.2 to Xbox GDK with two upscaling models
Developers can pick between Full INT8 and Lite INT8 for Xbox Series X and S, while ROG Xbox Ally handhelds get support through a preview driver.
AMD has added FSR 4.1.2 support to its Game Development Kit for Xbox Series X and Xbox Series S, according to pcgamer.com. The update gives developers two new upscaling models to choose from: Full INT8 and Lite INT8.
The Lite INT8 model is half the size of the Full model and carries a lower upscaling cost, according to the listed details. Developers decide which of the two models to implement in their games, and AMD has released a GDK sample that switches between Full and Lite at runtime so the two can be compared.
FSR 4.1.2 also reaches Xbox handhelds, starting with the top-end ROG Xbox Ally range. Access on the ROG Xbox Ally X and X20 requires a preview driver from Asus, the maker of the handhelds.
AMD says FSR 4.1.2 upgrades DirectX 12 games that already use FSR 3.1 or newer.
