Well, there's Valve's approach for HL2 using just a bit more information... And spherical harmonics could be far too computation heavy...

At least Bungie uses lightmaps with direction information stored in SH.(halo lighting.zip, lightmap compression.pptx)
If I remember correctly Insomniac games use them as well.
Naughty Dog used at least per vertex SH for environments and have released compression paper on subject.

That's not ID's strength unfortunately. It seems they spend their resesearch budget on all aspects megatextures (compression/decompression/storing/fetching/etc.) and post-processing effects. The basic lighting scheme still looks pretty similar to Doom3.

I ripped the audio and listened it on the road this weekend. Carmack definitely needs a podcast, as he is really really great speaker.

As always though, one should take the technical details in his talks with a grain and of salt. :|

I would have thought you listen to Carmack FOR the technical detail.
