WebGL and Chrome: high resolution makes for bad performance
Not including other things in here, as far as I was into it last time, all those requestAnimationFrame methods are capped at 60fps, and can only go lower than that.
You can test it with this bit: http://cssdeck.com/labs/gvxnxdrh/. You can modify fps var as high as you wish, but animation wont go quicker than 60fps in any browser I had on my desktop.
