Thx. I will test tomorrow improvements between psmoservice v 6.0.6 and 6.0.8 (noisy tracking in steamVR)
Hi all
I am currently using Pi max version 1.2.75 (Release) With the steam VR drivers for my Razer Hydra & everything works perfect. I get some shakes with controllers if I turn my back completely away from my base station which is expected but still works & if I’m sat in my chair with the back of it covering the base station it still picks up the hydra controllers pretty well. I have a PS move controller & a camera from a old ps3 and was thinking about adding the bulb to the top of my 4k and the camera to the top of my monitor. My question would be, can I use just the one controller & one camera for head tracking? As I don’t need the hand controllers. If so how do I do it. I am also thinking about putting the Hydra base station on my ceiling so that the wires don’t get tangled so much if I turn more than 360. Any one else tried this with any advice? I went to Thorpe park recently & tried out the Derren brown ride, having never used a vive headset I was intrigued to see how good the visual was. Not bad but soooo Glad I went down the 4k root!! My honest review is that the 4k with Razer hydra is amazing. Just need head tracking and job done 
Head tracking is being actively discussed in the posts below. Once you look at it, you will get the results you want.
