Those browsers are generally limited to 20-30hz. Chrome supports GPU based compositing with the switch "--enable-accelerated-compositing". It's still a dev only feature. WebKit on OSX supports GPU compositing. I believe all the other browsers also have work in progress in this direction as well.

WebKit does hardware compositing on Windows as well. Of course WebGL is not there yet, but when it is, it will composite the WebGL canvas.
