I was a supporter of Rift (DK2, then CV1) for long date and I will update to 1 next-gen headset.
I bought a motion seat and I will receive very soon.
I need motion compensation to be able to use my Rift CV1 into my motion seat BUT there is no solution for Rift, ONLY for SteamVR compatible headsets.
SO I will give up Oculus to buy a SteamVR headset like the Valve Index.
If only Oculus let partially open its driver in order to implement motion compensation ...
