As Microsoft got into the swing of Build 2013, it shifted attention to Internet Explorer 11 during a press session here in the belly of San Francisco's Moscone Center.
"The browser is no long a commodity," said Dean Hachamovitch, corporate vice president, Internet Explorer, to set the stage before a crew of IE team members ran down the forthcoming features.
Following the morning's focus on Windows 8.1, now available in preview mode for download, the company said that IE11 preview is also out in the wild. IE11 is co-shipping with Windows 8.1 and those who want to check it out now need the W8.1. preview build to get going.
Microsoft drilled in that's its looking to create "more than just a browser" as opposed to competitors like Firefox and Chrome, one that's tied to users' preferences, search habits and that lessens device strain. The main thrust of the update is that it's optimized for touch.
IE sees improvements
There's a "stick to your fingers" quality to IE11, Hachamovitch said, with features like hover menus, a touch optimized address bar and more responsive swipe/pinch/tap control, all aimed at helping users browse through IE more snappily than before or on other platform s.
Microsoft has boosted the UI for touch, meaning users can swipe for forward or backward gestures, page prediction and per-rendering.
IE11 relies on the machine's GPU to process gestures and to accomplish offloaded image decoding, Microsoft said. A few company-run tests did show limited impact on a tablet's CPU and the company promised battery life takes less of a hit in IE11.
The company has added extra tab support in the updated browser, letting users have up to 100 tabs open per window. Again, a CPU prognosis shown by the IE team showed little impact.
Users will also see Favorite sites get added support. Folder and custom tile pics lend a personal touch.
IE11 also support plugin-free HTML5 video, and thanks to more power effi cient streaming in Windows 8.1, batter life for web video is stretched further than before.
New additions
Unlike before, IE11 also supports interoperable WebGL, a graphics platform used to enable accelerated 2D and 3D graphics.
The feat was achievable, Hachamovitch said, thanks to overcoming a security issue. IE11 scans for unsafe WebGL content and, working with the GPU, launches a software-based renderer to complement the graphic chip's work. A graphics subsystem failure, Microsoft noted, is no longer fatal.
IE11 will also support Google's SPDY protocol, though WebRTC is out of luck.
