FWIW, I saw with gDebugger that the sky dome is made of more than 23000 vertices, even if a small amount of them are really displayed on screen. In Rembrandt, several pass are done on 1/16th of the size of the screen (1/4th of each dimension), relying on the mag filter to cover the whole screen. This is the case of the blur pass in the AO or Bloom effects.
