Software offers generic 3d monitor or 3d device output and it will display side by side on your monitor that can be streamed to phone (but since its squished in half by that it wont be as good and as clear as vorpx+real vr headset)
As for try – there is a free mod for cyberpunk, but dont know if you can run that game and if vorpx can output sbs in a free mod as that setting is in vorpx control UI that is part of full software.
Other than that there are no demos or refunds for vorpx.
