When it came to adopting virtual reality (VR) in 2016 with the launch of the Oculus Rift, one of the biggest obstacles was the power of the PC. So, it became available only to customers who have a decent specialized computer to start the headset in the first place. Oculus solved this problem with Spacewarp Asynchronous Technology (ASW), which could provide higher quality VR on equipment with a lower specification. The company has now introduced ASW 2.0 to improve these gains even more.

ASW 2.0 debuted at Oculus Connect 5 (OC5) last year, describing in detail how it planned to improve the software. While the original ASW 1.0 helped improve the VR experience for low-end PC users, it was limited by several factors, such as activation only when the head rotates in 3DoF.

Thus, one of the biggest updates in ASW 2.0 is the addition of depth (6DoF). Oculus has combined it with another technology, Positional Timewarp (PTW), to enhance PC prediction. When it comes to patterns, ASW 2.0 can use depth data to separate objects before extrapolation, helping to solve reprojection errors.
Another ASW 1.0 problem was that it did not fight when the application fell below half the required frame rate. This is no longer a problem with Oculus stating: “even with a reduced frame rate, ASW 2.0 can maintain an acceptable representation in VR, since depth-based PTW reprojection works more accurately for lower frame rates than ASW 1.0 extrapolation.”

ASW 2.0 is already available to Oculus Rift users with applications, including Oculus Medium, Red Matter, Robo Recall and Oculus Dash. In fact, all ASW 2.0 should function, these are the depths provided by developers, so if the Dash interface is mixed with the application, it will be compatible with ASW 2.0, which is relevant for most applications in the Oculus Store built on Unreal Engine 4 or Unity. If no data is provided, the application will return to ASW 1.0.
A free upgrade will be great for those who want to upgrade their processor or GPU for a better VR experience, but cannot afford new hardware.
