Making NVIDA the preferred graphics card for KeyVR

Select Manage 3D settings
Select the Program Settings tab
Select KeyVR from the drop-down
If KeyVR is not available in the drop-down, Click Add and point to the KeyVR.exe
Select your NVIDIA graphics card under Preferred graphics processor
Click Apply and restart KeyVR

Go to the "Gaming" Tab
Click "Add" in the upper right corner
Browse to the KeyVR installation folder and ad the KeyVR.exe - Usually located at in one of the following locations:
