SDK

Features and Improvements

  • Shader improvements for probe data reads/writes
    • The probe data texture now uses the same layout as the irradiance and distance textures
    • This change makes probe data visualizations easier to understand
  • Adds a RWTexture2D variant of DDGILoadProbeState()
  • Uses the DDGILoadProbeState() convenience function where appropriate
  • Moved the data member of the DDGIVolumeDescGPU struct inside the GetPackedData() function so the struct size is the same on the CPU and GPU
  • Updated stale code comments (non-functional)
  • Bumped SDK revision number and version string

Bug Fixes

  • DDGIGetVolumeBlendWeight: fixed regression related to volume edge fade not respecting rotations

Test Harness

Features and Improvements

  • ProbeTraceRGS.hlsl: no longer performs lighting for fixed rays when probe relocation is enabled (performance optimization)
  • Adds a performance benchmark mode that collects CPU and GPU performance data and outputs the results to *.csv files
    • Press the F2 key to run a benchmark
  • Adds the ability to store intermediate textures (back buffer, GBuffer, RTAO, and DDGIVolume textures) to disk
    • Uses the zlib and libpng libraries for cross-platform compatibility
    • Press the F1 key to save the current image data to disk
  • VolumeTexturesCS.hlsl: minor updates to the layout order of visualized textures
  • Config file and documentation updates
