Essential improvements

Skip intro videos

Delete/rename video files[citation needed]
  1. Go to <path-to-game>\Movies.
  2. Delete or rename Attract.bik, Dice_Intro.bik and Legal.bik.
  3. Go to <path-to-game>\System.
  4. Delete or rename logo.bik.

Fix low mouse sensitivity

Configure user.ini

This game has extremely low mouse sensitivity on the highest setting, especially if pointer precision is disabled on Windows, and the mouse is not of high DPI.

  1. Open <Steam-folder>\userdata\<user-id>\57900\remote\user.ini
  2. Set MouseSensitivity to your desired value above 10.000000

Optionally, decrease MouseAccelDampening, as mouse smoothing makes overall sensitivity slower. Changing settings in-game reverts these changes and setting the file as read-only breaks the game. Make this .ini edit after configuring key bindingd etc.

FPS Cap only in multiplayer, which is capped at 60 FPS. The singleplayer is uncapped. Vehicle speed is slower than intended at higher frame rates; at very high frame rates (well over ~150 fps or so), certain vehicle segments cannot be completed as jumps cannot be done properly. Vsync can be used to cap frame rate to the monitor's refresh rate for these sections.
High dynamic range display (HDR)

There is a mod that allows the pc version of the main campaign in Japanese, albeit without the dub that was avaliable on consoles [1]. There apparently was work done to make the dlc work in Japanese as well, but no links seem to remain.

Issues fixed

DukeForever.exe caused an EXCEPTION_ACCESS_VIOLATION

Can be caused by faulty .ini files[citation needed]
  1. Turn off Steam Cloud for the game.
  2. Go to the configuration file(s) location.
  3. Delete both system.ini and user.ini.
  4. Launch the game
  5. Re-enable Steam Cloud if the problem is resolved.

Broken vehicle physics

At high framerates, certain vehicle jumps are impossible to successfully complete, even with correct timing and boost usage.
Limiting the frame rate to 60fps
Enable Vsync and set refresh rate to 60 Hz[11]

Blurry graphics

Disable Post Special Effects

The game's depth of field effect results in unusually heavy blurring of the graphics. Disabling Post Special Effects will disable the depth of field and make the graphics much crisper, but will also disable tone mapping, bloom, and ambient occlusion.

Re-enable developer console and use a console command to disable depth of field effect only
  1. Download Console Downgrader mod and follow the installation instructions provided on its page.
  2. In game press the key you've chosen for the | Type command to open developer console, delete the default input prefix Say from it and type r_dofpow 0 followed by Enter
This will effectively disable the depth of field post-processing effect while keeping all other post-processing effects active.
The console command will have to be re-entered on every game launch. The result persist on level changes however.


  • Duke Nukem Forever: Enhanced - This mod overhauls the gameplay while also adding quick saves,removes weapon limit and Depth of Field effect for new post processing effects

  1. They state Duke Nukem Forever as engine in game files and in interviews they use the term "Duke Engine", but it's closer in file structure to Unreal Engine 1 games with many issues either absorbed from later iterations of the engine or entirely unique.[3][4]
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/57900/ in addition to or instead of this directory. The app ID (57900) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
