Overview
- AMD made the updated FSR SDK available to developers on GPUOpen and GitHub, delivering the next Redstone release.
- FSR Upscaling 4.1 uses machine learning to rebuild lower‑resolution frames with sharper motion detail and better ultra‑performance and dynamic resolution modes.
- FSR Ray Regeneration 1.1 serves as an AI denoiser for ray‑traced effects with quality and memory improvements plus new debug views, debuting in Crimson Desert.
- The ML features target RDNA 4 and Radeon RX 9000 Series GPUs, with analytical fallback modes for older hardware, and certain modules require Windows 11 and Shader Model 6.6 via the DirectX 12 Agility SDK 1.4.9 or newer.
- The SDK supports DirectX 12 and ships with an Unreal Engine 5 plugin that still exposes FSR Upscaling 4.0.3 for now, while the package also includes Frame Generation 4.0.0 and a Radiance Caching 0.9 preview for broader integration.
