Comment on http://www.smashingmagazine.com/2012/04/24/a-closer-look-at-font-rendering/comment-page-1/#comment-722738
It might be helpful to add that even though sub-pixel antialiasing is the default text rendering method on Macs with built-in LCD panels, using a third-party external screen can result in all text being rendered using greyscale antialiasing.
It’s also possible for users to switch to greyscale rendering system-wide by unchecking “Use LCD font smoothing when available” in the “General” System Preferences panel.
In Safari and Chrome you can control the antialiasing method by using the -webkit-font-smoothing CSS property which can be set to “subpixel-antialiased”, “antialiased” or even “none”.
On top of that; all text on a non-opaque Core Animation layer will always be rendered without sub-pixel antialiasing (because of the way the GPU does compositing). You can see an example of this in the menu bar when you enable “Translucent menu bar” in the “Desktop” System Preferences panel.
The latter is especially relevant for web pages which use CSS 3D transformations. Since these are hardware accelerated in Safari,
