Does anyone else find it weird that Doom3 is going to have like 8 different rendering paths? The different paths are one of the main topics in John Carmack's most recent .plan update. One of the other main topics is a comparison between the current top cards from ATI and NVidia (for reference, when he says NV30 think "GeForce FX", and think of R300 as "Radeon 9700"). As usual, his comments are highly technical and concise. Here is one comment that might be interesting to people waiting for the game release:
There are some more things I am playing around with, that will probably remain in the engine as novelties, but not supported features
To me, this looks like the engine must be getting close to finalized, but I might be reading too much into it.
