For some folks artisitic merit or financial success of Halo 3 isn't what's really important: it's about how many pixels are on the screen. After there were some complaints about the 'truth' of the game's HD nature Bungie posted a missive on their site clarifying the output process for Halo 3's visuals. "Halo 3 uses not one, but two frame buffers - both of which render at 1152x640 pixels. The reason we chose this slightly unorthodox resolution and this very complex use of two buffers is simple enough to see - lighting. We wanted to preserve as much dynamic range as possible - so we use one for the high dynamic range and one for the low dynamic range values. Both are combined to create the finished on screen image. This ability to display a full range of HDR ... gives our scenes ... a steady and smooth frame rate, which in the end was far more important to us than the ability to display a few extra pixels."
