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.
Shadow Denoiser

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.
