So I have a 15" rMBP (running Yosemite 10.10), and the way Apple/OS X handles Retina scaling has been bugging me recently. The setting that "looks like 1440 x 900" is supposedly the "best" setting for Retina, which makes the display's density look like 1440 x 900 but rendered at 2880 x 1800. But as soon as it is stepped up to what "looks like 1680 x 1050", OS X actually renders 3360 x 2100, then scales it down to the 2880 x 1800 hardware (similarly with 1920 x 1200 at 3840 x 2400). This seems a bit wasteful, and would take a toll on battery life.
So what if I prefer the look/display density of 1680 x 1050 but don't want the performance hit of rendering 3360 x 2100 on a 2880 x 1800 panel? Is there a way to do this?
