What's new in the AMD FSR™ SDK 2.1.0?

Welcome to the AMD FSR™ SDK. This revision to the SDK introduces the AMD FSR™ Redstone DLL-based ML technologies.

New effects and features

AMD FSR™ Frame Generation 4.0.0

Introducing our new inference-based FSR™ Frame Generation, an advanced frame-generating solution that leverages state-of-the-art machine learning algorithms to generate high-quality interpolated frames.

AMD FSR™ Ray Regeneration 1.0.0

Introducing our new inference-based FSR™ Ray Regeneration, an advanced denoising solution that leverages state-of-the-art machine learning algorithms to generate high-quality output from noisy source inputs.

AMD FSR™ Radiance Caching (Preview)

Introducing our new inference-based FSR™ Radiance Caching, an advanced path tracing caching solution that leverages state-of-the-art machine learning algorithms to facilitate high-performance path tracing calculations.

Updated effects

AMD FSR™ Upscaling 4.0.3

  • Fixed a rendering error when surface dimensions are not multiples of 8.
  • API changes:
  • Added ffxCreateContextDescUpscaleVersion which must be linked to ffxCreateContextDescUpscale when creating a context to ensure correct behavior with future updates.

AMD FidelityFX™ Super Resolution Frame Generation 3.1.6

  • API changes:
  • Deprecated ffxDispatchDescFrameGenerationPrepare & ffxDispatchDescFrameGenerationPrepareCameraInfo, replaced by ffxDispatchDescFrameGenerationPrepareV2.
  • Added ffxCreateContextDescFrameGenerationVersion which must be linked to ffxCreateContextDescFrameGeneration when creating a context to ensure correct behavior with future updates.

AMD FidelityFX™ Super Resolution Frame Generation Swapchain 3.1.6

  • Modified internal implementation to ensure future ABI compatibility.
  • API changes:
  • Added ffxCreateContextDescFrameGenerationSwapChainVersionDX12 which must be linked to ffxCreateContextDescFrameGenerationSwapChain*DX12 when creating a context to ensure correct behavior with future updates.

AMD FSR™ API

  • Minor non-API breaking additions:

Updated Components

Starting with AMD FidelityFX™ SDK 2.0.0 the effects, previously combined in amd_fidelityfx_dx12.dll, are split into multiple DLLs based on effect type. Please see Introduction to FSR™ API for details.

PDBs are provided for the effects DLLs.

Updated documentation

  • FSR™ 4 documentation.

Deprecated effects

None.

Deprecated components

All SDK version 1 effects are now deprecated to that version of the SDK. For any pre-existing FidelityFX features (including the legacy FidelityFX Super Resolution sample), please refer to FidelityFX SDK 1.1.4.
