Ben Vanik has already done some research on the ARB_timer_query extension, so he'd be a good one to fill in the blanks on questions like this. It's something that I was looking at tackling in the near future, so I'd be curious to know just how much of an impact it would have on the accuracy of these benchmarks.

- Will it work in the way browsers use the context? (as in does the GPU processes context map cleanly to a WebGL context)
- ES does not have the extension, would that block introduction of it?
- Can Direct3D9 do those?
