ZDNet's Googling Google blog points out that getting GPU acceleration going in your Chrome Dev version is simply a matter of right-clicking your Chrome shortcut and adding a parameter to the end, just as we've explained in the power user's guide to Google Chrome. In this case, that parameter (or "switch") is --enable-accelerated-compositing.

Where can you try out your new graphics-card-assisted browsing and rendering? Oddly enough, at Microsoft's Internet Explorer 9 Testdrive site. There will be, assuredly, other sites that support GPU acceleration in the near future, but for now, it's neat to see how fast you can get your browser going.
