Thank you for the tip! 
Finally got my hands on a VR-headset myself so I had to try it. Very cool!
My VR-headset is a "Windows Mixed Reality by HP" headset and it works fine using VorpX. I just followed Arron's steps above and it worked.
VorpX doesn't officialy support anything other than Oculus Rift and HTC Vive at this time so it was a gamble that paid off for me.
TIP: Make sure to set the in-game video and screen resolution options before you launch the game in VR-mode since it won't save your changes if you do them while in VR mode. (I selected 4:3 1280x1024) I also maxed the FOV using VorpX's ingame menu (press DELETE) to reduce "fish-eye".
