Eh, gimmick for some, sure. For others it's a whole new world that they won't leave. For example, got an Oculus for the gimmick and didn't think I'd be so attached to it, but I cannot go back to playing any flight or racing simulator without it again, it's simply not the same. I tried the new FS2020 briefly on launch, but had to go back to X-Plane as FS2020 still doesn't support VR headsets.
Quest and Quest 2 can play Steam games like Alyx. Since X-Plane is on Steam, I'm going to tentatively say yes. You just need to buy a PC link cable for the Quest. You can get away with a wireless to PC link... but you'll get more lag
Probably not, Quest 2 is basically running mobile hardware right? X-Plane is a fully fledged flight simulator that barely runs on a powerful desktop PC on highest settings. I'm using a Oculus Rift currently.
My understanding is Quest 2 can run Rift games using the optional link cable. But I'm not sure if that means it will take advantage of higher resolution on Quest 2 or whether X-Plane devs have to do something new.
What is irrelevant is if Quest runs with X-Plane or not, even if it doesn't.
The original subject of this thread was if VR is a gimmick or not. I initially replied that yeah, for some it's a gimmick and for others there is really no alternative. Now we're plenty off topic here :)
