If your rendering window is an exact multiple of the target resolution, sure - a 1280x960 window can provide the same visuals as a 640x480 display, at only a 4x fill rate hit. For 1280x1024 displays, though (which are somewhat more common), some of the source pixels will stretch out onto two display pixels, where some other source pixels stretch out onto three. -Dave LeCompte
