That's odd, I use current Aurora and Chromium dev channel. Well, on Linux. Both use only one core for the browser, and Xorg uses "another core". Firefox uses 10% more CPU and the animation is butter smooth. Chromium uses 10% less CPU and the animation is a little choppy. It looks like Chromium is throttling or something. None of them use more than 40% CPU on the core used. Video driver is intel i915, acceleration works.
