AMD FidelityFX Denoiser includes specialized spatio-temporal denoisers optimized for specific workloads:
- Shadow Denoiser: Designed to denoise a shadow mask created from tracing jittered rays towards a single light source.
- Reflection Denoiser: Designed to remove noise from the result of tracing jittered reflection rays based on surface roughness.
Supports:
- DirectX®12.
- Vulkan®.

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.

Microsoft® Game Stack Live: Denoising Raytraced Soft Shadows on Xbox Series X|S and Windows with FidelityFX
This presentation will explain how the AMD FidelityFX Denoiser allows for high-quality raytracing results without increasing rays per pixel, and deep dives into specific AMD RDNA™ 2-based optimizations that benefit both Xbox Series X|S and PC.
Hybrid Shadows Sample
This sample demonstrates how to combine ray traced shadows and rasterized shadow maps together to achieve higher quality and performance.
Reflection Denoiser Features
- High performance spatio-temporal denoiser, specialized for reflection denoising.
- Tile Classifier to skip non reflective areas.

- Temporal Variance Guided Tracing.
Includes:
- Classifier pass for reflection rays and denoiser tiles.
- Spatial filter pass.
- Temporal reprojection pass.
- Gaussian blur.
