well behind me there is the whole living room, with glasses, bottles, lots of reflective stuff.
I'm sure that moving the head to look around can be intuitive with some training, I was using Bustr's setting, with a very sensitive profile that allowed me to look on my 6 with a ~15 degrees head rotation. I could track an enemy in a 1V1 without any issues, but three problems stopped me.
I don't look straight at my screen, especially when aiming. The view moving while firing is a pain.
I make HEAVY use of the over nose view, I have found some workarounds, but they are only workarounds.
When looking at your high 7:30 then your high 4:30, you have to look at all the positions in between via your 12 oc (your neck doesn't do 360 degree). I don't have that problem with the hat, and it severely hampers my possibilities to adjust for a shot while my enemy is still on my 6 in a reversal.
In short its a lot of work and training, for zero improvement in my flying. Getting used to a throttle and pedals was hard, but the benefit was evident.
