Supporting OpenXR will bring a multitude of benefits to BMS. Firstly, there is no need to use Steam and the VRAM overhead it imposes.
Secondly, hand tracking will be possible with headsets such as the Oculus Pro and 3 or by using a LeapMotion controller (great if you have a G2). This will allow the interaction with the cockpit using hands instead of a mouse.
Other useful apps are also available such as OpenKneeboard.
