Ya I ran the SteamVR test again and still failing as only getting 60fps in the steamvr test.
Ah, I just commented below but didn't see this. You've got VSYNC forced on somehow for the application. Not sure if you setup a GLOBAL VSYNC option in the NVidia Control Panel but you shouldn't have that. Make any changes manually on a per-game basis (program settings, not global settings if you need to further modify VSYNC, AA or some other setting).
You might consider DDU as discussed, or check the NVidia Control Panel-> manage 3D settings-> disable any added settings there.
*If it shows 60FPS still during the test, then go to NCP-> manage 3d settings-> program settings-> "add game" then add the "VR" title that shows up.
Then drop down to VSYNC and change that to OFF, then SAVE settings.
