Ya, I heard / read the 3DO port was rushed, or something. Though I did notice something about the 3DO version of Doom. Although the framerate is poor, the resolution is VERY good. Even using just AV cables, 3DO Doom looked super-sharp on my 35 inch Trinitron. Noticeably more so than the Jag, 32X, PS or SNES versions.
I wonder if this is the reason they had such a hard time with the framerate? They set the resolution too high, therefore it ran choppy? Maybe.. The music is great on the 3DO version though. I still found it playable, but ya, not as good as the Jag version. Not even as good as the 32X version... I'd call it equal between the 3DO and SNES versions. The SNES version runs smooth enough, but they really hacked the graphics to hell. It barely resembles Doom at times. Whereas the 3DO version retains that traditional Doom look and looks very sharp. Just a shame about the framerate and the control is not the best.
It's not higher resolution on the 3DO version, but the 3DO's hardware (forgive me if I use the wrong word here) interpolation. Basically everything on the 3DO is displayed on a CRT TV (just like your Trinitron) in full 480i, whereas those other consoles display at 240p (skipping every other scanline) so the 3DO picture is sharper, even though the actual resolution of the game is ~320x240, it's diplayed within a 640x480i "window". This advantage disappears with modern TV's since they don't use scanlines and use all the pixels on-screen regardless of the source resolution.
Though, I do know that in the Jag version it has a horizontal resolution of only 160, and the 3DO version may be ~320, I haven't played it, and it's possible that the other versions (all being ports from the jag) may also have used 160 for horizontal res...so maybe you are seeing a better resolution at least horizontally.
