Reducing weight and increasing performance are two of the most important factors in pushing standalone XR headsets forward. While Meta has shown off its own Orion AR glasses prototype using a wireless compute unit, Meta’s CTO Andrew Bosworth doesn’t think a similar setup is the magic bullet for standalone VR gaming.

Bosworth, who is also head of the company’s Reality Labs XR team, held another one of his Instagram Q&As earlier this week, where he typically delves into a wide variety of topics—some professional, some personal.

In the latest session, Bosworth expounded on the subject of wireless compute units, and how the company thinks they aren’t the right fit for its standalone VR headsets.
