Opera enables hardware acceleration, matches IE9, beats Firefox and Chrome (video)
Like Chrome, Opera has opted to use OpenGL for hardware acceleration -- at least for now: DirectX, and presumably Direct2D, support is coming at a later date. The OpenGL backend means that Opera will be capable of hardware accelerating almost every platform -- including OS X, smartphones and Web-enabled TVs -- unlike IE9, which can only be used with Windows 7 and Vista.
WebGL support is also a nice touch, but with so few examples of it being used on the Web, it's hard to get excited about it. Google Body works just fine, however -- but the awesome Flight of the Navigator WebGL demo, which will blow you away in Firefox 4 and Chrome, doesn't seem to work in Opera.
Anyway, now it's time for the bit you've been waiting for: a side-by-side comparison of Opera, Internet Explorer, Firefox and Chrome. You will probably be surprised by the results. Watch the video after the break.
