Huh. I use Safari / OS X on a 4 year old MacBook Pro. I keep it locked on the integrated CPU and it worked fine, barely increasing the system load. Only one or two of the effects near the end made any noticeable difference.

Of course you're pushing 4x as many pixels as me.

Try Safari (you have to enable WebGL in the Develop menu). I wonder it's a Chrome issue.

Safari on my rMBP 13" did the same thing, heh. Still worth it. Amazing work.
