Rendering speed issues? (Score 1)

I've been using chrome for a day now, and I must say I'm very impressed, particularly with the ability to see the resource usage. This was immediately useful for me, as cpu-hogging flash applets have always been a pain to find and kill.

The one thing that's bugging me is that the rendering speed seems too be quite a bit worse than FF3. I can see this on sites like espn.com with their drop-down menus -- the menu item highlighting lags a little bit behind the mouse. It's kind of annoying, especially under heavy cpu load or laptop cpu-throttling mode. Has anyone else seen this?

The javascript performance appears to be great, but blasting bitmaps to the screen quickly is important, too.
