- announces the multi-vendor Vulkan extension VK_EXT_ray_tracing_invocation_reorder for Shader Execution Reordering (SER) to reduce divergence in ray tracing workloads
- explains how SER uses hit objects to separate ray traversal from shader invocation and allows the GPU to reorder invocations for improved coherence
- provides best practices, GLSL/Slang code examples, and how to profile with NVIDIA and AMD tools
- benchmarks Shader Execution Reordering (SER) using the Evolve pipeline path tracing benchmark across NVIDIA, AMD, and Intel GPUs
- tests reordering strategies based on material index and material properties mask to improve wave coherence
- shows significant performance improvements on NVIDIA hardware, while AMD and Intel showed minimal or no improvement
- implements a spatial hash structure to cache and accelerate ray-traced ambient occlusion for static scenes
- presents hash functions using PCG and xxhash32 with position and normal quantization to create cells that accumulate AO samples
- discusses distance-based cell sizing, conflict resolution via linear probing, and temporal management to handle hashmap capacity limits
- announces AMD GI-1.2 as part of the Capsaicin Framework v1.3
