I am using Windows 10 with 2 video cards a GForce 1080 where Oculus Rift is plugged in and a 1060 where my monitor is plugged in.
X-Plane 11 loads fine without VR selected but then upon selecting and restarting PC it hangs after starting and loads up to "Loding VR..." (50% progress bar) and 2 images then show up and it seems to switch back and forth between the 2. Both stuck at 50% never getting any further - Rift shows loading message - "If this takes a long time..." I have let it run for an hour but it never gets past this. I have to kill it in Task List.
