Steam Audio Beta 15 has added support for ray-tracing via the open-source AMD Radeon Rays technology. Steam Audio can use ray tracing to bake indirect sound propagation as sounds bounce around a scene until they hit a source. Thousands of ray tracing probes can be used in a scene and AMD Radeon Rays technology can speedup this operation up to 150x as it is GPU-accelerated and works on any modern AMD, Nvidia, or other GPU. "Reverb bakes that required an hour using the built-in ray tracer with a single thread should now take less than a minute using Radeon Rays on a Radeon RX Vega 64 GPU." What is Radeon Rays? Radeon Rays is a software library that provides GPU-accelerated algorithms for tracing coherent rays (direct light) and incoherent rays (global illumination, sound propagation). Radeon Rays is highly optimized for modern GPUs, and provides OpenCL and Vulkan backends. Steam Audio uses the OpenCL backend, which requires a GPU that supports OpenCL 1.2 or higher.
