The New Doom Iii Engine Is Still Being Built
In response to the closed thread. What you saw with the release of the geforce III was NOT the DooM III engine! It was simply a demonstration that ID put together using what they had at the time. Just as the Unreal engine goes through iterations so does ID's engine. Unoptimised and all that. Some of the content of that video was preliminary work on DooM III. But the engine itself is still being built. Actually.. it might be around 1/2 finished by now... as they were full steam ahead on it around January This year.
