I liked especially the 2012 Q&A with John Carmack: http://fabiensanglard.net/doom3/interviews.php http://fabiensanglard.net/doom3/interviews.php The blog author goes full nerd, like (paraphrasing) "You did this genius thing making a frontend/backend pipeline for rendering. Was this inspired by LCC? What are the advantages to a monolithic renderer?" and Cormack answers practically "Oh, didn't help that much, because of an unexplainable quirk of OpenGL it only worked well on my developer machine." :-p
