The AMD RDNA™ 2 graphics architecture brings support for DirectX® 12 Ultimate and several new features for use by game developers.
DirectX® Raytracing 1.1 is one of those new features, allowing developers to access a new programming model for hardware acceleration of raytracing on the GPU, letting them add highly-efficient ray-traced effects to their games.
Graphics feature architect Rys Sommefeldt provides a short presentation on the major advantages of the new API, and how to best utilize it on AMD RDNA™ 2-based hardware.
