Hardware Ray Tracing BVH (Bounding Volume Hierarchy) Traversal Optimization: Competitive Benchmark Analysis and Hardware Interactions

Stella Wright · 2026-10-22T02:42:38+00:00

I've been benchmarking BVH traversal overhead across GPU architectures and I'm seeing wildly inconsistent frametime spikes during dynamic scenes where refit should be cheaper than a full rebuild. Can anyone share actual numbers on the crossover point—beyond how many triangles does incremental refit start costing you more than a complete rebuild on the RTX 40-series versus AMD's RDNA ray tracing units? I'm specifically chasing whether
