In short, affine texture mapping is very, very fast - important on those mid-90s consoles that couldn't exactly do anisotropic filtering for practically free. Doom was still 'relevant enough' that Carmack was worried about the perception the game could have if it was plagued with texture warp.ДЇabien Sanglard's article on PSX Doom has a pretty good demonstration of it. I guess the main takeaway from the Saturn version is Carmack really, really hated affine texture warping. Even GamePro's middling review for Saturn Doom pondered the idea of Final Doom getting a Saturn port, the closest we would have gotten to any sort of engine upgrade, which of course never happened. The chances of seeing just an enhanced version of an already released game would have been slim to none at that point, especially for the Saturn.

Keep in mind that by the time Saturn Doom was released in Spring 1997 the Saturn was running a distant third behind PSX and N64 in terms of both sales and popularity, plus the fact that Doom in general was starting to get dumped on by critics for being 'too old' (aka not Quake/Goldeneye/Turok). Also pretty sure DF Retro managed to find out that the Japanese version running better was a myth.

The US version DOES still have the multiplayer in the game code it seems, just that the option to select it from the main menu was coded out for whatever reason. No special editions that fix it or anything. The US version was lacking and wasn't fully baked. The European version had multiplayer, and the Japanese version of the game was more optimized. I believe it would have been a very good port if it wasn't for John Carmack. What would have happened if they stuck with the custom engine? Obviously the game would have run a lot better than what we got, and maybe the extra content would have been added since no extra time would have been wasted on switching engines. The final result was the game not running very well as well as missing content. That resulted in a more rushed development as they had to switch engines which meant not having the time to implement everything as well as not being able to get it optimized. Well see what happened was that originally it was going to have a custom engine that made the game run better, but Carmack stepped in and told them not to use it. Remember Doom on the Saturn? It's hailed as a bad port for its frame rate and misinformation.
