Aerofly is still a beta and admittedly not nearly as developed in flight model yet (kinda of vanilla FSX at best in some aircraft). It is VR from the ground up though and the devs seem quite involved in growing it. We shall see. It did make Bronze in Steam's Top Seller VR list so they are incentivized.
Xplane's VR is early and needs lots of work. I also don't like the messy setting menus. It is a serious civilian simulator for sure though.
DCS is hindered somewhat by the age of it's engine but most of the aircraft have professional flight models. The PFMs are tested by real world pilots. In fact when Eagle Dynamics first created a P51 in a sim that had only modern aircraft at the time, they were asked why. They said because we own a P51 and wanted to see how close we could get. It became the standard for their PFMs. Most of their birds are "study sims" and everything not classified works and is as it actually is in the real aircraft. The helicopters (my faves) are awesome to fly in VR. Your video is ironic as DCS has a Harrier study sim. I fly for the love of flying more than combat so I don't suffer any problems in DCS as I don't usually have a lot of other aircraft in the scene to deal with. GPUs haven't been as important as CPUs in it but the 1080ti did offer a nice bump for me in DCS as did DDR4. I would see a moderate increase if I put in an 8700 cpu mostly from higher clock but can't justify that build when everything else I run is fine.
When I do get the urge to dogfight, it is usually in IL2 BOS in a FW190 or such. I like old fashion air combat as it's more up close and personal. The best in VR for me will be when WW1 is added to the IL2 engine (it's coming). 1C having merge with 777 Studios is finally going to give us the rebirth of Rise of Flight era planes and that in VR will be sublime. Can't wait.
I have IL2 in my wish list but I'm waiting (hoping) for the battle of Britain. I'm more into civilian flight sims (I always wanted to be an airline pilot) but the Harrier is my favourite airplane but if I were able to relive an historic air war personally it would be the Battle of Britain.
We are so lucky that this technology is out an improving and letting people experience stuff that would normally be out of reach if not impossible to experience.
