Following a long announcement, Facebook has now officially released the optimized version of the Asynchronous Spacewarp 2.0 (ASW) rendering engine for Oculus Rift and Oculus Rift S. The enhanced version combines Asynchronous Spacewarp with Positional Timewarp (PTW) for an optimized VR experience.
Asynchronous Spacewarp 2.0 – Lower latency, better performance and fewer artifacts
The new update to Deploy Asynchronous Spacewarp 2.0 has been officially released to enhance the VR experience for Rift users. ASW technology powers on automatically as soon as performance drops are imminent. Threatens a Framedrop below 90 FPS, the practical feature turns on, calculated at 45 FPS a synthetic image from the last two images and inserts it in front of the lost frame. This results in a much smoother frame rate and users always get the full 90 Hz.
The new update extends the technology and enhances it with some handy features. Thanks to a performance walkthrough, the ASW 2.0 now also powers on at less than 45 FPS, allowing even weaker PCs to enjoy more advanced VR experiences. Powerful high-end PCs also benefit from this and can use higher resolutions.
In addition, the Positional Timewarp now ensures lower latencies even in spatial movements. In addition, a new method of data processing, which provides better recognition of the objects against a background, provides for less artifacts and thus for an improved display of the contents.
How this works is demonstrated by Oculus in the form of a video:
According to Oculus, the improved ASW 2.0 is expected to be compatible with most of the available VR experiences based on Unreal Engine 4 and Unity, as they provide the necessary depth information from scratch. For example, Medium, Red Matter or Robo Recall and, of course, Oculus Rift Dash and Oculus Home should be able to access the new feature.
If no support for ASW 2.0 is available, the predecessor ASW will be used.
