Doom 3 Programmer on OGG, Ultra, 60FPS Play

Cryect writes "Appears that Doom 3 is making use of Ogg Vorbis to reduce memory usage for sounds. This comes from id programmer Robert Duffy's latest plan update where he says: 'When we started on memory optimization, most levels used between 80 and 100 megabytes of sound data. We made the choice to move to .OGG for quite a few sounds which effectively removed the problem for us.'" Duffy also comments on texture usage in 'Ultra' mode ("In Ultra quality, we load each texture; diffuse, specular, normal map at full resolution with no compression. In a typical DOOM 3 level, this can hover around a whopping 500MB of texture data") and framerate ("The game is capped at 60fps for normal game play. For render demos, like what was used for the HardOCP stuff, we run those at full tilt which is why you will see 60fps.")

Re:Wouldn't this add to the processor usage?

Note the 500 MB of memory for textures. They need memory badly. Bumping the CPU speed slightly probably makes for better minimum specs tan going over 500MB of ram.
