Title: Use doms high resolution timer

From HTML5 rocks:
There are a few situations where you'd use this high resolution timer instead of grabbing a basic timestamp:
- benchmarking
- game or animation runloop code
- calculating framerate with precision
- cueing actions or audio to occur at specific points in an animation or other time-based sequence
