I didn't link the video, I linked the comments of people who did try it and found it amazing. Just to spread awareness you can always try it if you have a set
Without headtracking and the simple Grimrock movement and the amazing depth perception you get from SBS view with a VR headset it should be impressive
I haven't dabbled with 3rd party software like VorpX and tridef making non VR games VR compatible as I have a Pimax 4K and compatibility isn't as good compared to oculus/htc vive.
I bought the Pimax as it was cheap and offered a higher resolution than other headsets to play exclusively VR racing games like dirt rally.
