X-Plane is supposed to be as close to a simulation as possible, it claims that a commercial version is used by professionnals, therefore, unless that kind of controllers has been recently approved by the ICAO, FAA, etc, using these controllers is not simulation as it it supposed to be when it comes to flying aircrafts.
In fact these controllers were not designed for that kind of VR. They were trying to provide an answer to questions raised by using VR in games, not in real life simulation. Dirt Rally is using VR, with wheel, shifter and pedals, and is absolutely fantastic. No arms flailing, things knocked over and whatnot, only pure driving just like it is done in real life.
Had it been using these controllers, well ...
