AMD FidelityFX™ Stochastic Screen Space Reflections (SSSR)
The AMD FidelityFX SSSR effect provides an open-source library to easily integrate stochastic screen space reflections into your game.
The AMD FidelityFX™ Hybrid Reflections sample shows how to combine AMD FidelityFX™ Stochastic Screen Space Reflections (SSSR) with ray tracing in order to create high quality reflections.
Supports:
- DirectX® 12
- Vulkan®
Part of the AMD FidelityFX™ SDK
Download the latest version - v1.1.4
This release of the AMD FidelityFX™ SDK adds the following features:
- Additions to the API and fixes for issues discovered.
Features
- Hybrid Reflections:
- Uses AMD FidelityFX™ SSSR to replace ray tracing intersection tests.
- Reshades re-projected pixels for accurate material evaluation.
- Supports lower resolution reflections using AMD FidelityFX™ Super Resolution (FSR) 1.0 upscaling.
- Uses per-pixel feedback to reduce hybridization cost.
- Ray-traced reflections.
- AMD FidelityFX™ reflection denoiser.
Debug view
Left side: The hybrid stochastic reflections composited into the final scene.
Right side: Debug visualization which shows which pixels have their reflections calculated by ray tracing, screen space reflections, or a mix of the two.
Using hybrid stochastic reflections, decals which are rendered in screen space (and not present in the BVH) may be included in the reflections.
