If playing it locally in DOSBox on Linux here are some settings to try out in your ~/.dosbox/wolf3d.conf copy of ~/.dosbox/dosbox-x.xx-x.conf

  [cpu]
  
  core=auto
  cputype=auto
  cycles=10000
  cycleup=10
  cycledown=20

And at the bottom of the file add your own mount like this:

  [autoexec]
  # Lines in this section will be run at startup.
  # You can put your MOUNT lines here.
  
  @ECHO OFF
  MOUNT C /games
  C:
  CD WOLF3D
  WOLF3D
  EXIT

Then start the game with:

  dosbox -conf ~/.dosbox/wolf3d.conf
