GNOME 3.8 and the "new" Classic Mode using 3D acceleration

["." <dcMhOYBdpZkH web de>]

So now that GNOME 3.8 has "Classic Mode"[1] I'll see how loud my
notebook's fan gets, since from the picture it seems that it uses 3D
acceleration. 3D acceleration was always something which gets my (and my
friends') notebook fan very loud and decreases battery time. 3D for
desktop, at least for older notebooks, is unnecessary (I don't know if
> =Sandy Bridge notebook are louder too when using 3D).
