Wouldn't it be much more convenient then to buy a VR headset which actually follows your head movements because it's physically head mounted? Not to mention that it provides a stereoscopic view of the scenery. I guess the price is a hurdle.
VR headsets that are any good are quite expensive so price is definitely a factor I think. Plus they introduce a lot of eye fatigue and you have to wear something on your head which gets tiring.
I have a VR headset and still prefer head tracking. It's more comfortable, and becomes second nature after an hour or two of use.
I tried to play Elite Dangerous in VR. It is a very nice game to do that with but personally I found the heavy HMD got uncomfortable inside of a half hour, and I had difficulty reading text. It's fine for combat missions but if I want to design a trade route I'd rather just use my normal monitor.
The other problem is that I have a fancy throttle and stick with lots of extra buttons and switches. I know common functions by touch but if I wanna toggle exterior lights or something I have to look down and find a label.
For me choosing a screen + head tracking vs VR is like choosing to use speakers instead of headphones. The headphones sound way nicer and give much more immersive soundscapes but sometimes you want to have some tunes going and not have your ears get sweaty.
