Hardware Ray Tracing (DXR / Vulkan RT)

Hardware-accelerated ray tracing uses dedicated fixed-function silicon to accelerate BVH traversal and ray-triangle intersection tests: NVIDIA RT Cores (Turing and later), AMD Ray Accelerators (RDNA 2 and later), and Intel Xe Ray Tracing Units (Arc Alchemist and later). Exposed via DirectX Raytracing (DXR 1.0/1.1) and VK_KHR_ray_tracing_pipeline. Enables physically accurate reflections, area light shadows, ambient occlusion, and full path-traced global illumination in real time in games and DCC applications.
