Air to air shots are where the VR really shines with its full scale view. I must say too, once you get everything working, you get a true sense of what the limitations of the view WW2 pilots had having been strapped into the seat. The movement is one to one so when you say real stretch to look up, to get a view of that red, it is very real.
It is almost embarrassing to find yourself reach for the P-38 wheel after a lazy, hands off auto climb or try to rest your arm on the tank turret. It happens more than you would think.
Dive bombing is now much improved although still short of regular AH. I don't look at the altimeter on drop. I depend on the size of the object. VR throws you off with the change of object size. The maps seem a bit easier to read.
Your mind, I guess you would say, starts accepting the lower quality of video graphics seemingly tuning more to the incredible 3-D objects HTC artiest have prepared. My favorite plane so far in 3-D is the P-47 just because of the shear size of the plane.
