Pimax with Virtual Desktop with out any Oculus or any other account just pimax. Virtual Desktop needs Oculus account? How to we use it then. I installed Virtual Desktop but it asks for Oculus account information. I see others say it works with Pimax, ok then. I searched for hours. But no one talks about the requirement of Oculus account. How to use Pimax without Oculus. This is the first VR head set I bought.
