The DK2 has a built in latency tester. The SDK has an API to access it: ovrHmd_ProcessLatencyTest

Can we expose it in the browser?

That's for starting a latency test, and you may need to use the rgb color to clear the screen (which the device then waits for). It's unfortunately not as simple as just making a call -- you have to actually do rendering.

Worth the trouble I think. Having an accurate latency measurement is crucial, especially in WebVR where we have a lot of ground to cover on performance IMO.
