SOH ADMINISTRATIONI have the Rift and it was a mind-blowing experience. You actually sit in the plane instead of behind a monitor. Do consider the FlyInside add-on (https://flyinside-fsx.com/); it is a program that gives much better VR support than P3D itself.
Sketchy, I have not yet installed 4.2, but in 4.1 I do not encounter the problem you have. A problem I do have is that sometimes my HOTAS warthog joystick file takes very long to load and then the buttons for FlyInside do not work.
