FidelityFX

FidelityFX is our series of optimized, shader-based features aimed at improving rendering quality and performance.

These features are designed to be easy to integrate, and we ship HLSL and/or GLSL versions of the effects to allow you to target any API.

Contrast Adaptive Sharpening (CAS)

CAS is a low overhead adaptive sharpening algorithm with optional up-sampling.

Combined Adaptive Compute Ambient Occlusion (CACAO)

CACAO is a highly optimized adaptive sampling ambient occlusion implementation.

Luminance Preserving Mapper (LPM)

LPM is is a tone mapping and gamut mapping solution for HDR and wide gamut content.

Find out more:

Single Pass Downsampler (SPD)

SPD provides an RDNA-optimized solution for generating up to 12 MIP levels of a texture.

Stochastic Screen Space Reflections (SSSR)

SSSR is a highly optimized hierarchical screen space traversal kernel for reflections.
