I've taken advantage of a function in madVR that will enable NVidia stereoscopic in the event it is not enabled prior to 3D playback.  Playback of HDR disables NVidia stereoscopic and does not enable it when finished for example.  This has already been remedied using the code and method here, launched from KODI.  But, for those times 3D playback is desired when not using KODI, such as testing naked in Windows Explorer for example, and assuming NVidia stereoscopic has been disabled for any reason, 3D playback will function as normal.  Since it is launched from madVR, only madVR capable players will benefit such as MPC.  This will have no affect on PowerDVD since it does not call madVR.  If you are using PowerDVD without launching from KODI, and 3D plays as 2D, chances are NVidia stereoscopic is disabled.  You will have to manually enable it.

Create a .bat file named 3D ENABLE.bat and put it wherever you like.  I put mine alongside the others in AppData\Roaming\Kodi\userdata folder.  Edit this code into it:

@echo OFF
"C:\Program Files (x86)\NVIDIA Corporation\3D Vision\nvstlink.exe" /enable
EXIT 

Create another .bat file named 3D DISABLE.bat and put it wherever you like.  I put mine alongside the others in AppData\Roaming\Kodi\userdata folder.  Edit this code into it:

@echo OFF
"C:\Program Files (x86)\NVIDIA Corporation\3D Vision\nvstlink.exe" /disable
EXIT

If you have copied the profiles I use or have something similar, open madVR settings and navigate to RENDERING and select the 3D profile.  In the 'command line to execute when this profile is activated' enter the address of the 3D ENABLE.bat you just created.  Mine is C:\Users\DAN\AppData\Roaming\Kodi\userdata\3D ENABLE.bat.

In the 'command line to execute when this profile is deactivated' enter the address of the 3D DISABLE.bat you just created.  Mine is C:\Users\DAN\AppData\Roaming\Kodi\userdata\3D DISABLE.bat.

I have added a picture of the setting with the other madVR settings pictures here https://forum.kodi.tv/showthread.php?tid...pid2616287
