What resolution best matches the DK2's native resolution ?

Hi there.

I received my OR DK2 a few days ago and I am somehow confused about resolution. At least half of the demos I tried so far allows you to choose which resolution you want to render the demo in.
It confuses me a little.
I know what the DK2 screen native resolution is, however It is also more than obvious that the pictures is stretched, deformed and split in half inside the headset. I don't know (if anyone does), how the Rift handles it.
Regarding my quite low GPU abilities (AMD 7850), you will understand I would like as much as possible not to compute "useless" pixels (even if it makes the pictures a little more aliased).
Basically, I would like to know what resolution to select before the game/demo starts in order to get a pixel-perfect render inside the DK2. Not down-sampled. Not over/super-sampled.

I can say without a doubt, in a usual situation, if a game is running at the native resolution of the screen or not. But it is far more difficult with a VR headset.

PS : I could bet the answer will differ regarding which engine is used. I am also afraid it is impossible to answer because the deformation is a post-processing effect.

Yet the gpu generates 75 (1920 x 1080) frames per second. Each frame contains the information from two independent (960 x 1080) renders, and is then split. I believe this is why SLI doesn't work out because it's set up to do alternate frames rather than each doing half of every frame.
Or I could misunderstand the question.
