Oculus recently posted a developer guide on Asynchronous Spacewarp (ASW) 2.0, which combines the power of ASW 1.0 with Positional Timewarp (PTW) to provide higher-quality and lower-latency VR. The blog entry builds on an initial post on ASW 1.0 with more technical details and tips on how to make sure VR applications are ASW 2.0 ready.

The blog post first discusses the difference between ASW 1.0 and 2.0, including the above video showing debug arrows of the calculated motion vectors per tile used for content-motion warping by ASW, followed by a deeper breakdown into the algorithm used by Oculus runtime to use ASW and a deeper dive into the technical details.
