The way the high resolutions work is that the screen is rendered at 2x then scaled down to fit the display. This does lose a bit of that subpixel antialiasing, so you're right that it doesn't appear quite as crisp as the native retina scaling. Hopefully this is something they're working on - Quartz could theoretically be modified to detect the scaling factor for the display and render text, shapes, etc to match the native pixels.
- johansch 14y agoWhen you scale down a subpixel-rendered text that way, you pretty much destroy the subpixel rendering effect. What I think happens: in modes other than 2x, text is rendered without subpixel rendering. It is scaled down, and possibly a slight sharpening effect is applied in the process. Anyway, the result is not as good as the awesome font rendering we are used to in OS X.

- glhaynes 14y agoIs that in a "Retina app"? If so, my understanding is that text for them is rendered by the system at the right size (so not rendered then rescaled) at any resolution.
