DirectX Raytracing is supported in Windows 10’s October Update

Microsoft has officially released their Windows 10 October 2018 feature update, enabling support for the company’s DirectX Ray Tracing (DXR) API, enabling developers to support real-time Raytracing in future DirectX 12 gaming titles. 

The DXR API has been built from the ground up to support ray tracing acceleration hardware from all hardware vendors, with Nvidia taking the lead with their RTX 20 series graphics cards, the first generation of graphics hardware to offer bespoke ray tracing acceleration hardware. 

Battlefield V, Metro Exodus and Shadow of the Tomb Raider are expected to be the first three games with support for DirectX Ray Tracing. With the release of Microsoft’s Windows 10 October 2018 update, Windows users now have access to both hardware and software support for DirectX Ray Tracing, making it a matter of time before we see DXR enabled gaming titles and benchmarking utilities. 

Ray Tracing will enable levels of realism that is unachievable than traditional rasterisation techniques, with areas like reflections, shadows and ambient occlusion acting as highlights. Below is a video which showcased 4A Games’ use of DXR to create hyper-realistic ambient occlusion within Metro Exodus. 


Outside of Ray Tracing, Microsoft has also confirmed their plans to integrate machine learning techniques into DirectX with DirectML, which will allow game developers to incorporate inferencing techniques into games using a low-level API. 

DirectML will become available sometime in Spring 2019. Microsoft expects this API to be used alongside DXR to lower the computational requirements of Ray Traced workloads.
