AMD FidelityFX Denoiser includes specialized spatio-temporal denoisers optimized for specific workloads:
- Shadow Denoiser: Designed to denoise a shadow mask created from tracing jittered rays towards a single light source.
- Reflection Denoiser: Designed to remove noise from the result of tracing jittered reflection rays based on surface roughness.
Supports:
- DirectX®12.
- Vulkan®.
