The VR Inspector view allows you to inspect how your application is using VR APIs. Both Oculus and OpenVR are supported in NVIDIA Nsight.

With the Oculus API, the sections of the VR Inspector view include the following:

Swap Chains — Lists all swap chains and their associated texture resources and description fields, with links to the Resources View for inspection
Mirror Textures — Lists all mirror textures and description fields with Resources View links for the associated texture(s)
Render Desc Queries — Shows all of the calls to ovr_GetRenderDesc, along with the parameters, to confirm that the proper eyes, FOV values, etc. are correct
HMD Description — Gives details on the actual HMD device connected to the machine and all of the limits for that device

When using OpenVR, you will see the following in the VR Inspector view:

Show API Usage — Brings up the Events List view filtered by OpenVR calls
OpenVR Version — In the top left, under Show API Usage, the minimally compatible version of OpenVR you are using will be displayed. This may be lower than the version your application has targeted, due to the fact that it may not be using any features of later API versions.
Mirror Textures — Lists all mirror textures and description fields with Resources View links for the associated texture(s)

The following sections return interface dependent information:

VRSystem — displays the render target size
VRSystem Tracked Devices — displays information for each tracked device currently connected
VRSettings — displays all of the VRSettings properties
VRChaperone — displays the play area information
VRCompositor — displays rendering and compositing statistics
