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 FidelityFX FSR4.

New effects and features

AMD FidelityFX Super Resolution 4 (FSR 4.0.2)

Introducing our new inference-based 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 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 FidelityFX features (including the legacy FidelityFX Super Resolution sample), please refer to FidelityFX SDK 1.1.4.
