Wow, due to a typo in VR Beta 1 the IPD (InterPupillary Distance or gap between the eyes) was set to 6.5mm instead of 6.5cm. Fixing this simple error has transformed a pretty good VR experience into a phenomenal one!
Previously the cockpit looked 'large' (due to the lack of stereo separation) now the cockpit feels like it wraps around you and the sense of depth to the controls, displays and HUD is great. I'm a VR convert!
I've also added an IPD setting so you can adjust it to your particular eye distance.
