The AMD FSR “Redstone” SDK includes four neural rendering features optimized for AMD RDNA™ 4 architecture graphics cards: AMD FSR Upscaling, FSR Frame Generation, FSR Ray Regeneration, and FSR Radiance Caching. While the ML-powered features require RDNA 4 architecture-based hardware, analytical fallback (FSR 3) modes are available for upscaling and frame generation features, supporting RDNA 3.5 architecture and earlier graphics. Below are more details about the specific FSR features being updated in the SDK 2.2 release.
AMD FSR 2.2 SDK Now Available: Comes With FSR 4.1 & Ray Regeneration 1.1 Support… AMD FSR 2.2 SDK Gives Devs The Ability To Add Redstone's Neural Rendering Technologies, FSR 4.1 & Ray Regeneration 1.1, In Their Games Easily Neural rendering is transforming real-time graphics, enabling developers to deliver higher visual fidelity and performance than ever before. …
