AMD FidelityFX Denoiser

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®.

Optimized for Shader Model 6.0+

State-of-the-art algorithm

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.

Reflection Denoiser features

  • High performance spatio-temporal denoiser, specialized for reflection denoising.
  • Tile Classifier to skip non reflective areas.
  • Variable Rate Traversal: From full rate for mirror reflections down to quarter rate for glossy reflections.
  • Temporal Variance Guided Tracing.

Includes:

  • Classifier pass for reflection rays and denoiser tiles.
  • Spatial filter pass.
  • Temporal reprojection pass.
  • Gaussian blur.
