How Retina macbookpro works with screen resolutions

Seems pretty simple
System settings allows you to select 5 screen sizes – 1024 x 640, 1280 x 800, 1440 x 900(default one), 1680 x 1050, 1920 x 1200
Once you select one, it retinezes it (x2 on both dimensions) so you get 2048×1280, 2560×1600, 2880×1800, 3360×2100, 3840×2400

then it upscales (in case of first two) ot downscales(in case of last two) the image to fit 2880×1800.
So blur (in case of upscale) and lost pixels (after downscale) are not that noticable when pixels are small (220 pixel per inch).

    I wonder how much does that scaling hit the performance, when using Ps in “More Space” mode (aka 1920×1200)

    So basically it’s not only pointless but its eating gpu power in order to do so then unless I’m missing something?

    How does it work in Boot Camp? Do you get a screen with a 2880×1800 resolution?

    do macs run games across 2 screens if windowed? with out the need for eyefinity style driver settings.

    i want to set up 3600×1920 across 3 24inch 1200p screens and hoping the new support will work out

    do u know any gfx cards that suports 3 screens at once in OSX?

    they definitely have rough edges to sand down.

    In either of the “best” or 1680 settings, this very board gets a little weird in Safari.

    “” gets clipped at the bottom.
