Windows 10 October 2018 Update now available, adds official support for DirectX Raytracing (DXR)

And the moment a lot of gamers have been waiting for has finally arrived. Microsoft has released the October 2018 update for Windows 10 that adds official support for DirectX Raytracing (DXR). With this update, DirectX Raytracing will work out-of-box on supported hardware and the first wave of DirectX Raytracing in games is coming soon.

As we’ve already reported, the first games that will support DXR are Battlefield 5, Shadow of the Tomb Raider and Metro Exodus, with more games to come in the near future.

According to Microsoft, the first DXR games will worth with NVIDIA’s RTX technology. RTX will make DirectX Raytracing run as efficiently as possible on NVIDIA’s hardware (which is the only GPU manufacturer right now that supports real-time ray tracing).

Microsoft claimed that it has designed DirectX Raytracing with hardware trends in mind.

“By representing DXR as a compute-like workload, without complex state, we believe that the API is future-proof and well-aligned with the future evolution of GPUs: DXR workloads will fit naturally into the GPU pipelines of tomorrow.”

As of 2pm PST today, this update is now available to the public. As with all our updates, rolling out the October 2018 Update will be a gradual process, meaning that not everyone will get it automatically on day one.
