Report: OpenXR Spec In-Progress; New Nvidia Vulkan Driver

The Khronos Group has announced OpenXR, an open standard for VR and AR applications and devices. Their OpenXR Working Group is creating this open and royalty-free standard to combat (API) fragmentation.

The Khronos GroupIn short, fragmentation slows the adoption of VR/AR devices, generates unnecessary work for developers and limits the ability of new and innovative devices to gain popularity.


The OpenXR standard comes in two parts: an Application Interface ("write code once that will run everywhere") and a Device Layer ("allows VR/AR runtimes to interface with various devices").

In related news, there's Vulkan 1.0.42. Mentioned in their Vulkan at GDC 2017 PDF document, and it introduces new extensions. As GamingOnLinux writes: "We know Khronos will be at GDC, so it's likely some of the Vulkan talks will mention these new extensions for VR use."

These new extensions have already made it into Nvidia's beta Vulkan driver 375.27.12. It's unclear to me if this means we can/should now move from 375.27.10 to 375.27.12. The SteamVR-for-Linux GitHub page still says 375.27.10.

Also, Valve's Joe Ludwig talks about OpenXR in a Voices of VR podcast interview. I haven't listened to it yet, but that should be interesting. Voices of VR writes: "Given that it was first announced in December 2016, then I'd expect that we might be seeing a 1.0 specification for OpenXR sometime in the first half of 2018."

Careful though, that didn't work for me.
