Why is Chrome so much less graphically performant than Safari?

Hey HN,

Front End Developer here, long time reader. I'm trying to identify why Chrome seems to struggle when it comes to animation performance while Safari is able to render everything without a hitch. Is this because Safari has hooks into the OS that Chrome does not? Is this because Google adopted blink in lieu of webkit? And most importantly is there a remedy out there?

Take the following site for example: http://scrollrevealjs.org/

In Chrome my scrolling gets choppy, however everything remains beautifully buttery in Safari. As a developer what can I do to improve the performance of my sites that rely heavily on animation?

Thanks!
