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.

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.
