There were no full 3D games in 1993. Quake was still 3 years in the future.

Duke Nukem had some 2.5 D stuff going on that was more powerful than what doom was doing, but just barely. I think the first fully 3d game that meets your definition is probably 'Descent'
Maze/Maze War, Chuck Yeager's AFT, Elite. Not as polished or fast as Descent or Quake on a Pentium chip but you'd need to redefine 3D with rather obtuse constraints to exclude them.
