What's new in the AMD FidelityFX™ SDK 2.0.0?

Welcome to the AMD FidelityFX™ SDK. This major revision to the SDK serves as a launching pad for all of our new and upcoming DLL-based ML technologies. We are pleased to present the first of these with the public release of AMD FidelityFX™ FSR4.

New effects and features

AMD FidelityFX™ Super Resolution 4 (FSR 4.0.2)

Introducing our new inference-based AMD FidelityFX™ Super Resolution 4, an advanced upscaling solution that leverages state-of-the-art machine learning algorithms to generate high-quality, high-resolution frames from lower-resolution inputs.

Updated effects

AMD FidelityFX™ Frameinterpolation Swapchain 3.1.5

Fixes out of command lists crash if create swapchain >2 frames of latency and using non-async Frame Interpolation.
Fixes an alt-tab deadlock scenario when Frame Generation is enabled.

AMD FidelityFX™ Super Resolution 3.1.5 (FSR 3.1.5)

Fix for possible negative rcas output.

AMD FidelityFX™ Super Resolution 2.3.4 (FSR 2.3.4)

Fix for possible negative rcas output.

AMD FidelityFX™ Super Resolution (FSR) API

  • Minor non-API breaking additions:
    ffxQueryDescUpscaleGetResourceRequirements for any upscaler provider to get info on what resources are required or optional.
    ffxQueryDescUpscaleGetGPUMemoryUsageV2, ffxQueryDescFrameGenerationGetGPUMemoryUsageV2, and ffxQueryFrameGenerationSwapChainGetGPUMemoryUsageDX12V2 to get GPU memory requirement before effect context is created.

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 AMD FidelityFX™ API for details.



PDBs are provided for the effects DLLs.

Updated documentation

  • Simplified FSR 2, FSR 3 & Frame Generation documentation - previous documentation remains in AMD FidelityFX™ SDK 1.1.4.

Deprecated effects

None.

Deprecated components

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