AMD FidelityFX™ Denoiser

Shadow Denoiser specific features

Spatio-temporal denoiser, specialized for shadow denoising.

Tile classifier to skip work on areas without spatial variance in the shadow mask.

Increased contribution of spatial filters on low temporal sample counts.

Analysis of the local pixel neighborhood to counter ghosting artifacts.

Version history

The AMD FidelityFX™ SDK 1.1.4 is a patch release that includes additions to API and fixes for issues discovered with AMD FSR 3.1.0 to 3.1.3.
Exposed 4 new tunings to reduce AMD FSR upscaler ghosting in newly disoccludded pixels or highly reactive pixels.
Changed the default value of fMinDisocclusionAccumulation to -0.333 (from equivalent of 0.333 in AMD FSR 3.1.3) to reduce disocclusion ghosting.
Added ffxQueryGetProviderVersion to get version info from created ffx-api context.
Exposed ffxDispatchDescFrameGenerationPrepareCameraInfo as a linked struct. It is a required input to AMD FSR 3.1.4 and onwards for best quality.
Added frame generation debug checker support.
Dropped unused interpolation command lists if frame generation callback fails, to fix infinite wait at swapchain destruction.
General fixes to Vulkan® Frame Interpolation Swapchain.
General framework fixes and updates.
Frame pacing debug line added to Vulkan®.
Added new FFX error when create frame interpolation swapchain results in E_ACCESSDENIED in DX12 due to overlay or capture software.
Enabled support for frame interpolation swapchain on Windows® 10 1909 and potentially earlier versions.
Fixed flipped disocclusion factor from previous and current backbuffer.
Fixed HDR mode issues in Cauldron sample.
Fixed MSVC C compile errors including ffx-api.
The AMD FidelityFX™ SDK 1.1.4 also updates the following to address select issues:
AMD FidelityFX™ Brixelizer GI 1.0.1
AMD FidelityFX™ Breadcrumbs 1.0.1
