Do you have tested the latest NVIDIA driver "390.65-desktop-win10-64bit-international-whql,exe" ?
It cause freezing screen when the steamVR off. and it can't be recognize with pimax. just show me "Not Ready".
old version of nvidia driver was fine. I'm using the "PiPlay_Setup_22.214.171.124_setup.exe".
My graphic card is GTX 1070.
Ah... I think... noloVR driver causing a crash when the steamVR off... I uninstalled the noloVR driver. and it is fine now.
but... I have a problem to use the noloVR's controller as the vive controller without noloVR driver...
The piplay offer the basic noloVR driver. but this controller's button do not work on the unity. trigger doesn't work.
I have tested the noloVR SDK's unity package too. but it is same thing... ah.. sorry... noloVR driver also do not work on the unity too... Hoo... I think.. noloVR is suck.... on the unity. I have tested unity 5.X 2017. both same thing...
ah... NVM.... it's horrible thing.. it doens't matter for uninstalled noloVR. stuck again my pimax... with the NVIDIA 390.65 driver... Maybe I have to find more old version. I have tested 388.43 driver before. but it getting laggy and skipping frame. and shake a screen on the unity3D. Hmm..
I always clean uninstall the graphic driver in the safe mode .
Hmm... Piplay 126.96.36.199 which you linked main page of this site. getting failed during installing. I have turned off all anti-virus. Hmm.. what is wrong with me. Did I something wrong? hoo...
