When using one of the many available apps to run the rMBP at its native resolution instead of as a retina screen, will it still render at twice that, like with 1920x1200, and then downscale it? Or will it render straight to 2880x1800. The former case sounds to me like a huge hit to the performance.
Got a tip for us?

rMBP scaling at 2880x1800

I do have a question regarding resolutions though. If you run one of these retina displays at it's full resolution with no scaling, is that harder or easier on the graphics card or does it make no difference?
Should be basically the same at 2880x1800 'native' and at 1440x900 HiDPI (which is also 2880x1800).
The 1680x1050 HiDPI and 1920x1200 HiDPI modes however take more GPU power than native 2880x1800.
As obi-wan once said - you will find that many of the truths we cling to depend greatly on your point of view
I find 2880x1800 extremely nice when using photoshop & lightroom. pixel for pixel images with a UI that is still there but basically out of the way. I think I'll still be using these programs at native rez once they are updated for retina.
Thanks you for all your answers. Based on several of them I gathered some courage and installed resolutiontab, and it seems like it does indeed render at 2880x1600 instead of 5760x3200 as I feared (based on a screenshot which comes out at 3840x2400 in 1920HiDPI mode).
Correct, I've measured this and WindowServer uses about 0.75% more CPU overall during UI redrawing.
For you. I don't remember the last time I wasn't running 2880x1800 other than when messing with some non-HiDPI modes to see what it was like.
Easier because the computer doesn't need to carry out any scaling routines. Not that it's a particularly noticeable difference, but it's there.
well obviously some people out there will always do stupid/silly things. i'm not speaking for those folks. and congrats on wasting your money on a screen you're not even utilizing.

I have my computer set whenever say Photoshop or Lightroom opens up, the resolution is changed to 2880x1800 non-HiDPI (native). Sure the tool bar looks small, but my images looks perfect. Until Adobe and others update their applications, I will have to live with this. Some things like Word looks fine. I've seen worse with text, but I can't work with blurring images.
