  • 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.

Note to developers

AMD FidelityFX Denoiser includes a spatio-temporal denoiser optimized for reflection denoising. 

A denoiser optimized for raytraced shadows will be added here in a future update. If you are a developer working on a raytracing title then please contact your AMD representative for early access.

Comparison

How it works

1. Noisy reflection input
3. Temporal resolve
2. Spatial resolve
4. Gaussian blur

FEMFX

A multithreaded CPU library for deformable material physics, using the Finite Element Method (FEM)

DepthOfFieldFX

The DepthOfFieldFX library provides a GCN-optimized Compute Shader implementation of Depth of Field using the Fast Filter Spreading approach.

GeometryFX

GeometryFX improves the rasterizer efficiency by culling triangles that do not contribute to the output in a pre-pass. This allows the full chip to be used to process geometry, and ensures that the rasterizer only processes triangles that are visible.

ShadowFX

ShadowFX library provides a scalable GCN-optimized solution for deferred shadow filtering. It supports uniform and contact hardening shadow (CHS) kernels.

TressFX

The TressFX library is AMD’s hair/fur rendering and simulation technology. TressFX is designed to use the GPU to simulate and render high-quality, realistic hair and fur.
