| FEATURES
High dynamic range (HDR)
Highly optimized
Open source. MIT license
- Can be configured to work with any positive RGB input working color space.
- Can be configured to target any RGB output color space (target any display)
- Solution is completely ALU-based without any LUT, so has the capacity to run asynchronously with workloads which are bottlenecked by other hardware limits.
- Supports packed FP16 for better performance on Vulkan.

Using AMD FreeSync™ Premium Pro HDR: Code Samples
Part 4 of a series of posts on AMD FreeSync™ Premium Pro Technology. Here, we look at how to enable FreeSync Premium Pro with all next gen graphics APIs.
Using AMD FreeSync™ Premium Pro HDR: Gamut Mapping
In this tutorial, we will be going over what gamut mapping is, how we implemented a gamut mapper to show how FreeSync HDR works, and some pitfalls with different gamut mapping algorithms.
Using AMD Freesync™ Premium Pro HDR: Tone Mapping
In part two of this tutorial, we cover the terminology of tone mapping, what tone mapping is, as well as different monitor features that influence how well a tone mapper will work.
Using AMD FreeSync™ Premium Pro HDR: Color Spaces
The first in a series of four tutorials related to AMD Freesync™ Premium Pro HDR. This tutorial covers terminology related to color.

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.
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.
