There’s another factor here I have thought about but don’t know how it’s handled and it’s ipd. If the game “cameras” are set at a different distance apart than your actual pupil distance, there will be a difference in how close or far and how big things will appear. World scale may correct this appropriately or it may not. Not sure if the hmd sends it’s ipd setting to the game or not either. In the G2, It’s max is 68mm, but my ipd is 69.5mm, so it falls slightly short of what I need. It doesn’t seem to adjust in-game camera separation as far as I can tell. If the in-game camera distance is adjustable or known, this could be corrected more precisely.
