Features
- Hybrid Reflections
- Uses FidelityFX SSSR to replace ray tracing intersection tests.
- Reshades re-projected pixels for accurate material evaluation.
- Supports lower resolution reflections using FidelityFX Super Resolution (FSR) 1.0 upscaling.
- Uses per-pixel feedback to reduce hybridization cost.
- Ray-traced reflections.
- FidelityFX reflection denoiser.
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.
AMD FidelityFX Denoiser
AMD FidelityFX Denoiser is a set of denoising compute shaders which remove artefacts from reflection and shadow rendering.
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.
