Firmware V12 update:

Oculus Link:
-AMD GPUs are now supported! Please see the Oculus Link Compatibility Guide for more details.

-We have separated the system audio from VR audio so that you'll only hear VR game audio while using Link, instead of hearing game and desktop audio together.

-The Oculus Debug Tool now supports changing Oculus Link graphics settings.

-General performance improvements and stability fixes.

-The microphone has been temporarily disabled. We are working to re-enable it in a future software update.

Casting:
New features built on top of phone casting will allow you to better guide someone else through their first VR experience while casting from the headset to your phone. For example, while your friend is wearing the headset, you can act as “tour guide” for them using several new options to do things like launch the Oculus First Steps tutorial or reset the headset view.

Voice Commands (Beta):
-Use your voice to navigate, control your device, and find new apps and games by clicking the Voice Commands button on the Home menu. This beta feature is rolling out gradually, so not everyone will see it in this software update.

Hand Tracking:
-Use your hands as an additional input method for navigation and controls in the Home environment and some Oculus applications. After opting-in via Settings > Experiments, you will be able to view a tutorial on how to use hand tracking. This tutorial will also be available in your Library.
