I have made the move from Oculus Rift where I used P3D v3 with Flyinside Flight Simulator and thoroughly enjoyed it.
I have now made two leaps, one to Oculus Quest 2 with Fibre Optic Cable, and the other to P3D v5.1
I am so looking forward to getting FlyInside Flight Simulator working with it, so I do pray it is compatible, lest my bubble is burst.
