Anti-aliasing (AA)
Vertical sync (Vsync)
60 FPS and 120+ FPS
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.

Field of view (FOV)[edit]

Instructions[citation needed]
  1. Go to the configuration file(s) location.
  2. Open user.ini.
  3. Change all three instances of DefaultFOV=90 to your desired value

Issues fixed[edit]

DukeForever.exe caused an EXCEPTION_ACCESS_VIOLATION[edit]

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. If everything goes well you can turn on Steam Cloud again

Broken vehicle physics[edit]

On some PCs, certain vehicle jumps are impossible to successfully complete, even with correct timing and boost usage.
Enable Vsync[11]

Blurry graphics[edit]

Disable Post Special Effects[citation needed]

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.

  1. 1.0 1.1 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.
