Enemy Territory: Quake Wars used an earlier version of it but only for the terrain. I think Rage was the first to use it for everything.

Unfortunately nowadays id Software doesn't seem to be at the cutting edge of engine technology anymore. Most interesting new developments now come from Unreal Engine as far as I can tell. Like virtual geometry (Nanite) or efficient ray traced direct illumination (MegaLights).
Doom the Dark Ages uses some pretty advanced (and performance intense) illumination techniques which i believe are comparable ro megalights.
They ripped our Carmacks texture streaming stuff outta the engine years,ago though
No, they are only using ray traced global illumination, which Unreal Engine already had several years prior (Lumen). They are not second place either, because several other engines also had it before id Tech.

I'm pretty sure they are still using texture streaming. There is no alternative to that.
Damn i feel old. The ue5 demo is now 3 years old and lumen is considered old tech now? Jeez...
The original "Lumen in the Land of Nanite" demo is nearly six years old actually (May 2020).
Fuuuuuuccckkk
The id tech 8 engine is a whole lot more performant than the unreal 5 engine and absolutely does what it needs to, fantastically, I would add for the game it was made for.
