Well, for a start I didn’t have the back ‘strap’ low enough. So fixing that certainly helped.
I had VR Lens Lab lenses in my Rift, and I was able to secure them in the O+ with no problems. They work great.
Performance wise in DCS I’m fairly impressed. One of the things that would bug me with the Rift was the way it struggled in a fly by. The aircraft would ghost as it went by the camera. With the O+ that doesn’t happen at all.
I’m having issues in X-Plane with not being able to move the mouse cursor when in VR (that never was a problem with the Rift). The brighter displays are great though!
