Not sure if anyone can help me but I am getting something really odd when in X-Plane and I enable VR.
The situation is this: Set up a flight in a small helicopter (VSkyLabs Cambri) and enter the sim in 2d. Helicopter is configured for a cold and dark start so it is just sitting there. Hit the button I have to enable VR, then re-center the display and watch as the helicopter seems to drift right, slowly (1 cm a second?). Disable VR, and the drift stops. RE-enable VR and it starts again. Sometimes, depending on my head orientation or position, I can get it to slowly rotate. No other device does anything to move a cold/dark helicopter.
I had something similar in MSFS … ages ago with that old Bell (?) helicopter. If I was to look up and left, the helicopter would turn slowly right while in flight. Which was weird as heck and very hard to pin down to the VR view (because, looking somewhere away from the line of flight and I thought that it was an inadvertent input I was entering).
Any one else experience this?.
It only happens with the headset on my head. Which adds to the weirdness. If I put the headset on my lap. no movement. If I put my hand over the center of the lenses then the movement/rotation happens. What the heck!
Edit: HP Reverb. Only seems to affect helicopters with skids … maybe the phantom force is too low to affect the resistance of wheels?
