Evidently you can set the workable space to be 1024 x 640, 1280 x 800, 1440 x 900, 1680 x 1050 or 1920 x 1200.

Thanks. I'm very interested on the specifics of this:

As a result of the upscaled rendering, there can be a performance and quality impact.

Thanks, very cool how they're doing the scaling. Everyone should be sure to check out the screenshots that go with the article.

It seems like even when you set to the 'effective' low resolution modes, it renders things very smoothly. It looks way way better than simply setting a display to a non native resolution.

Anyone tried Quartz Debug on it yet?

I want the desktop area of a 2880x1800 display that thinks it's at 72 ppi - no scaling.

Also, check out the dimensions of the screenshots. Looks like they first scale up 2x, then they scale (either up or down) to native panel res. That's rather inelegant - I'd expect them to do any simple raster scaling that needs to be done in software (in the GPU, even), then draw text and the more complex raster scaled images. This way results in things being fuzzier than they have to be.
