Rather than having to pull off your headset (mine G2) to see the real world, for instance to find a particular button on a hotas, or on another complex control setup, if you could push a button thats easy to find and enable/disable to have a brief view outside in the real world. You can do it from the VR controllers but when you need to move your hands from a yoke or hotas setup, or remove your headset, you break the immersion.
Just say the words ‘Torch On’ and the passthrough image will appear.
'Torch Off turns it off again.
