Lets see if I can help out with a few specs.
I7-7700 HQ @ 2.80
GTX1070 Driver: 22.214.171.12405
I have usinstalled PiPlay 1.1.92 again,
making sure to close out all the active processes
deleted all the files that were remaining
deleted the Steam VR settings that were here:"C:\Program Files (x86)\Steam\steamapps\common\SteamVR\resources\settings"
SteamVR wont load from the Pimax program and doesn't recognize the HMD
