The benchmark runs in Chrome 14+, Firefox 13+, IE 10, Opera 12 and Safari 5.1.7+ on the desktop, and in the mobile versions of Chrome, Firefox and Opera. It does not run in IE 9 because Microsoft’s browser does not implement WebGL's Typed Arrays, and in several mobile browsers which fail to execute some of the tests: Android Browser, Chrome on iOS 4 (due to iOS restrictions), and Safari on iOS 4.
