Anandtech says that the resolutions are actually calculated at double the resolution and then scaled down, so if you pick 1920x1200, the GPU actually calculates 3840x2400 and then scales it down to 2880x1800. The results apparently are fairly good compared to past attempts at non-native resolutions.
