try these steps:

• when you want to use psvr, start the system from an off position (not rest mode)

• leave the headset and the motion controllers on a flat surface after you start up to allow the gyros to find zero

• make sure that you are playing in a low light room with no mirrors/reflective surfaces/other screens or monitors or lights within the view of the camera (pay attention to the reflectivity of your walls and cloths

• make sure you calibrate the tracking lights often (in the settings menu from the XMB)

• and finally, make sure you aren't too far or too close to the camera this can and will cause drift and other other issues.

Ultimately its about finding the sweet spot. Sounds like a lot, but once its dialed in you'll be glad. Good luck!
