I think the lighting is baked, but due to the technique (virtual textures) the texture detail is much higher than normal. This gives the wonderful illusion of radiosity/GI in a scene even though the actual computed lighting effects may be on par with the original Quake. Thanks to the technique, textures are loaded as needed, placing less burden on GPU memory.

I give Carmack credit. It has surprisingly little to do with the iPhone specifically.

Sometimes I wish I was a real-time graphics researcher. It's so exciting to me! I may have missed my calling. Maybe....
