Description

AMD FidelityFX SDK 2.0 launches our neural rendering technologies for developers is a GPUOpen announcement by Jason Lacroix and Alexander Blake-Davies introducing FidelityFX SDK 2.0 as the vehicle for AMD's ML-based rendering path, starting with public FSR 4 upscaling.

It separates legacy effects onto FidelityFX SDK 1.1.4 while re-architecting API-based features around signed loader DLLs for upscaling and optional frame generation. FSR 4.0.2 targets Radeon RX 9000 Series GPUs; other hardware falls back to FSR 3.1.5. Prior FSR 3.1 integrations can receive Adrenalin driver upgrades toward FSR 4 and future ML frame generation. Requirements list DirectX 12, Windows 10/11, and Unreal Engine 5.2-5.7 plugin support.

It is for intermediate to advanced engine programmers integrating AMD upscaling or frame generation. Familiarity with DX12 plugins and shipping signed vendor DLLs helps.

The article is a free product-launch write-up with requirement tables and pointers to SDK docs and Discord feedback channels.

It is useful when planning an FSR 4 or Redstone-era integration and deciding whether to stay on SDK 1.1.4 effects or move to the 2.0 API DLL layout.
