SDK

Features and Improvements

  • Substantial code and API refactor
  • Added support for Vulkan
  • Added support for Linux (x86 and ARM)
  • Added support for bindless resource access models
  • Infinite Scrolling Volumes (ISV) feature is now available (no longer beta)
  • Improved multi-volume support, including GPU workload batching
  • Improved shaders with define driven feature and resource declarations
    • Shaders can now be used directly in any codebase that supports D3D12 or Vulkan, regardless of resource binding model
  • Improved Probe Classification accuracy and increased performance gains when classification is enabled
  • Moved DDGIVolume constants to structured buffer(s)
  • Reduced the size of DDGIVolume constants by 2x
  • Merged per-probe relocation and classification data into a single texture resource
    • Removed the R8 UINT texture resource used with classification
  • Substantial CMake and build system improvements
    • Removed unnecessary third party dependencies
    • Refactored and simplified the defines system
  • Refreshed and improved documentation and converted to Markdown

Bug Fixes

  • Infinite scrolling volumes now properly clear irradiance and distance data for probes that are scrolled
  • Probe classification now accurately tests each probe ray's hit distance against the probe voxel's bounding planes
  • Fixed probe rays no longer perform unnecessary shading and lighting
  • Fixed regression related to distance blending and sampling

Test Harness

Features and Improvements
