AMD has rolled out the latest update to its FidelityFX Software Development Kit (SDK), unveiling version 1.1.2 with significant new support for the Xbox Series X|S. More than just a technology for upscaling, FidelityFX presents a comprehensive suite of tools designed specifically for game developers to enhance visual fidelity. This fresh release centers on addressing issues previously identified in FSR 3.1.1 – the SDK’s prior iteration. Notable improvements with this update encompass the correction of depth format conversion errors in Vulkan and adjustments to extended depth formats within GLSL shaders. Additionally, the SDK license file has been repositioned for easier access. These alterations signify AMD’s ongoing commitment to refining their open technologies, promoting better integration for developers working across different platforms such as the PC and Xbox.
Key Enhancements and Fixes
The FidelityFX SDK 1.1.2 update not only extends support for Xbox Series X|S but also introduces numerous technical enhancements and bug fixes, with a strong focus on visual precision and developer tools. By switching color limitations to an ellipsoid from AABB, AMD aims to minimize “ghosting” effects that can break player immersion. The update includes significant improvements in shader compilation tools, especially in error reporting, enabling developers to quickly identify and resolve code issues. Additional upgrades feature support for frame distortion textures and memory leak fixes in DX12 during PSO creation, ensuring a smoother and more dependable development experience.
AMD’s Cauldron framework also benefits from extensive internal updates and optimizations, demonstrating the company’s commitment to continual improvement. With these advancements, FidelityFX SDK 1.1.2 provides game developers with a more robust and efficient environment to craft high-quality, visually stunning games. AMD’s dedicated support for open technologies reflects its broader ambition to future-proof game development across various platforms, ensuring the creation of immersive gaming experiences.
