That’s a weird one, I’ve never heard of the issue with the Oculus headsets in Elite. If I lift my headset up I’m literally one-to-one. Have you tried making small adjustments to the IPD setting?I'm only 6ft, so not exceptionally tall. If I lift up or peak out the nose of my headset, my in game arm is easily only 2 thirds the size of my real arm in terms of length and the hands are smaller too. It's the same on my CV1 and the Quest 2. Again, it's not quite as jarring as the discrepancy is on the Vive, as I tried it on my mates one and yeah, that is bad.
