At the "12 Gallagher Lane" gallery in San Francisco, Microsoft' IE team launched Internet Explorer 9 Platform Preview 3, that includes a number of major new features. The biggest additions to Platform Preview are support for HTML Canvas, audio/video tags, and performance boosts that largely focus on IE9′s hardware acceleration. In a series of demos showing off the new capabilities, IE team members gave us a taste of just how smooth advanced operations in the browser can be when they're taking advantage of a computer's multiple cores and GPU (historically most browsers only take advantage of your CPU and don't take advantage of a second core).
Here's are some screenshots of the Test Drive demos:
Microsoft used a variety of demos featured on its Test Drive site to demonstrate what the browser is capable of with these new features (they note that the site has been viewed 16 million times since it launched).
