Hi, it took me a while to get it to work. One thing that helped was to not start Steam VR before starting the sim. I started the sim in steam and after picking my flight and aircraft I went into VR mode thru the sim menu. One warning ,for a while all I saw was text in the VR window asking me to press the key to set the pilot POV and nothing on the keyboard would move me off that screen…I had to keep force quitting the sim. Then I saw that you can go into “General Settings” when not in VR, set the binding to a keyboard short cut (I set for space bar). Then I would go into VR mode and once in VR pressed the space bar and then I was in VR. Don’t know if that helps or if that was the problem you had. I do know there was an update to the Steam Client. Make sure you have updated Steam.
