Hey, great news! The delay is gone now. First I uninstalled all VR components
-Kinect
-SteamVR
-Driver4VR
-PSMoveService
Next I removed all registry entries referencing Driver4VR and PSMoveService, and a few other entries referencing FreePie, Immotion and other software I’ve used with Kinect/PSMove.
I then reinstalled everything including re-downloading the Driver4VR beta and installing the latest version.
Sorry I couldn’t give you move straightforward solution, but thanks for all your help!
