I too have been running a Dell Visor with the Kinect V2, and it seems to work sometimes. While the tracking is there, in VRchat my feet sometimes glitch out and are either both attached to one foot, or the tracking becomes minimal, as in large motions with my feet are barely registered. I will say though that the Kinect tracking doesn’t interfere with the WMR tracking at all, at least in my case. Really looking forward to V4 since I have limited space to work with, about 1.6 x 2 meters.
