I think I have the same issue. Did a flight today and I could always see the ground, weather was overcast at 5000 and I was at 8 and could still see the ground. Switch to standard X-plane weather and by by ground. Seems like the clouds are always in front of you, you can't fly through them. Flying in VR.
Yesterday on first run, it crashed with a Gizmo64 out of video memory. Today just hung on starting the flight. Something to do with gizmo64 but that topic doesn't have a support topic so here I am! After changing to 2D and doing the activation, it now seems fine. Seems to be a problem there with doing the activation in VR. Log.txt
