Horizon leveling requires a lot more cooperation from the developers/sim, as does turbulence manipulation/modification.
Maybe better just to ask to be able to tweak ‘camera’ parameters for the view used for the VR pilot. How fast is (e.g.) a 90 degree head movement in VR is converted to a 90 degree head movement in the sim, and reflected in the view. Shouldn’t be hard , as I see these parameters for all other cameras in the sim.
