I played DCS using Riftcat and driver4vr with kinect 360. It was 6 dof. but not stable. After few minutes needed to recenter. My adwise dont waist your time and money. It is friendly adwise. Before i Bought Lenovo explorer i waisted a lot of money for junk like Trinus, Riftcat, driver4vr, kinect 360....
I dont recomend VR using phone because it is not good for your eyes. nad it is only 60 Hz. Save you money for new PC and next gen VR.
