Halo3 not 720p Shocka!!!!

[Yaka]

with all the sodding sing and dance both MS and Sony have done about the "HD"
being on of the most prominent feature of thier new consoles. but it seems like a few Halo fanboys with a sharp eye noticed Halo 3 was not running in 720p but in 640p. Bungie on thier part have admitted so while giving thier explantions to the grumbling halo3 fans.

However, the interweb detectives did notice that Halo 3's vertical resolution, when captured from a frame buffer, is indeed 640 pixels. So what gives? Did we short change you 80 pixels? Naturally it's more complicated than that. In fact, you could argue we gave you 1280 pixels of vertical resolution, since 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.
