Raytracing is not a new technique, but until recently it has been too computationally demanding to use in real-time games. With modern GPUs, it's now possible to use rasterization for most of the rendering and a smaller amount of raytracing to enhance shadows, reflections, and other effects that are difficult to achieve with traditional techniques.
Our DXR tech demo runs in real-time on current GPU hardware and, because it builds on existing methods, it was relatively easy to implement into our DirectX 12 game engine.
We are proud to be one of the first developers chosen to work with DirectX Raytracing, and we are excited about the opportunities for this new API. I am happy to announce that we will be using DirectX Raytracing in a new 3DMark benchmark test that we hope to release towards the end of the year.
