-While in VR, your viewpoint is not limited to being inside the cockpit. If you have the proper setup and space to move around irl, you can actually "walk" outside your craft and see it from outside (and it's way cooler than what I can describe here).

-VR will only work with KSP using Direct3D 12, i.e. you need to use the "-force-d3d12" flag on the executable. It will not work if you try to run KSP normally. To enable the Direct3D 12 flag, create a Shortcut to either `KSP.exe` or `KSP_x64.exe`, and on the shortcut Properties, append "-force-d3d12" to the Target. Follow the [Install Guide](https://github.com/Vivero/Kerbal-VR/wiki/Install-Guide) if you're having trouble.
