Severe judder with head movement

New problem today… After a few minutes flying, it seems like the tracking of my headset (Oculus CV1) starts to lag severely. Whenever I move my head, the view judders, so much that it quickly becomes nauseating. However, the ATC screen stays perfectly still… which makes me think it’s not the tracking that’s the problem.

I noticed in another thread a problem that sounds similar, and suggested deactivating the ATC and VR Map from the overhead panel, but this had no effect. It also seems to me that the framerate isn’t affected, but I haven’t checked that.

I am actually quite happy that despite this, in the last couple of days I’ve at least had no CTDs. No really long flights, but before it wouldn’t last more than 5 or 10 minutes…

Anyone else had this experience?
