| COMPARISON
Are you an Unreal Engine developer?
The Unreal version of TressFX now supports 4.24.
| VERSION HISTORY
- Hair is skinned directly, rather than through triangle stream-out.
- Signed distance field (SDF) collision, including compute shaders to generate the SDF from a dynamic mesh.
- New system for handling fast motion.
- Refactored to be more engine / API agnostic.
- Example code includes compute-based skinning and marching cubes generation.
- DirectX 12 support.
- The biggest update in TressFX v3.1.0 is a new order-independent transparency (OIT) option we call “ShortCut”. It has bounded memory and potentially higher performance than the full per-pixel linked list (PPLL) method. Note, though, that it does not give quite the same quality result as the PPLL method, and thus represents a memory/performance vs. quality tradeoff.

Cauldron Framework
Radeon™ Cauldron is our open source experimentation framework for DirectX®12 and Vulkan®.
FidelityFX – Contrast Adaptive Sharpening
FidelityFX Contrast Adaptive Sharpening (CAS) provides a mixed ability to sharpen and optionally scale an image.
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.
