|enabled||Whether to enable sustained performance mode.|

On Daydream-ready devices, if Google VR Services is not present and enabled, this will prompt the user to install or enable Google VR Services before continuing. If the user continues without Google VR Services present and enabled, the Android OS will not enter VR mode, and some functionality may not be available (e.g. the controller).
