You're speaking about
Duke Nukem 3D, not the original Duke Nukem game from 1991.
In particular, the PS1 port was called
Total Meltdown, and it was subpar compared to the PC version, so no surprise there.
Duke3D did not use the same engine as Wolfenstein or Doom. It used its own
Build engine, which was technologically superior to the other two, and is still being modded in the present.
I urge you to play
Duke Nukem 3D: Atomic Edition with the eDuke32 source port, the High Resolution Pack and the Polymer renderer. It's come a long way.
There's also a new Duke Nukem game being developed right now called
Mass Destruction. 8 days until it's unveiled at
