Please, please, please. Don't have the default set to VR enabled on a fresh install. When I launched DCS it launched in VR mode and none of my HID's were responding. I spent 30min to an hour trying to figure WTF was going on. Let users enable VR on first install if they so wish. Don't force it out of the gate just because they have Oculus or SteamVR installed. I had to use my VR headset as my mouse to disable VR. Lucky I had some friends that were able to share with me that what I was viewing was the VR mode. Otherwise I would have just uninstalled this and gone back to other games, writing the 2.5 beta off as a failure.
Trying to get back into this game but so far i am left with a bad taste because of this. It seems more intuitive to start by default with standard display settings.
