At Connect 2021 last week, Meta revealed a new Quest rendering technology called Application Spacewarp which it says can increase the performance of Quest apps by a whopping 70%.
While similar to the Asynchronous Spacewarp tech available to Oculus PC apps, Meta says Application Spacewarp will produce even better results.
...
The technique achieves this by allowing applications to run at half-framerate (for instance, 36 FPS instead of 72 FPS), and then the system generates a synthetic frame, based on the motion in the previous frame, which is filled in every-other frame. Visually, the app appears to be running at the same rate as a full-framerate app, but only half of the normal rendering work needs to be done.

Lower Latency Than Full Framerate
Combined with other techniques, Meta says that Quest applications using Application Spacewarp can have even lower latency than their full framerate counterparts (that aren’t using the extra tech).

Differences Between Application Spacewarp (Quest) and Asynchronous Spacewarp (PC)
While a similar technique has been employed previously on Oculus PC called Asynchronous Spacewarp, Meta Tech Lead Neel Bedekar says that the Quest version (Application Spacewarp) can produce “significantly” better results because applications generate their own highly-accurate motion vectors which inform the creation of synthetic frames. In the Oculus PC version, motion vectors were estimated based on finished frames which makes for less accurate results.
Ja, da steckt Geld drin.... I know.
