• Combined Adaptive Compute Ambient Occlusion 1.4
• Contrast Adaptive Sharpening 1.2
• Denoiser 1.3
• Classifier 1.3
• Luminance Preserving Mapper 1.4

• Super Resolution 2.3.3 Upscaler
• Super Resolution 3.1.4 Upscaler and Frame Generation
• Super Resolution 3.1.4 Upscaler
• Variable Shading 1.2
• Blur 1.1

• Lens 1.1
• Breadcrumbs 1.0.1

Supported ecosystems

This version of the AMD FidelityFX SDK comes with samples that run on the following APIs:

• DirectX(R)12
• Vulkan(R)

The shader code which comprises the core of AMD FidelityFX SDK is written in HLSL and GLSL, and can easily be ported to other platforms which support modern shader models.

If you are a registered Xbox developer, you can find AMD FidelityFX features available as part of the Microsoft Game Development Kit (GDK).

Samples

All samples are written in C++, and use the FidelityFX Cauldron Framework sample framework.
