Microsoft tried to downplay the launch of Safari 5 by posting its own comparison video (below, Silverlight needed) showing Internet Explorer 9's performance with graphics hardware acceleration. Apple is touting use of the GPU for the Windows version of its browser, but IE9 even in its test phase is shown drawing demo sites noticeably faster than Safari. Microsoft didn't say how many of the tests, which exist on the IE9 preview site, were hardware-enabled for both.
