Call of Duty: United Offensive[edit]

Essential improvements[edit]

Version 1.1[edit]

The very first, as installed from the retail disc, unpatched version is also still played online:
Live Call of Duty 1.1 Server List (usually these servers don't require a valid cd-key to play)
Version 1.5 can also be downgraded to 1.1 following this tutorial: Call of Duty 1.5 to 1.1


The latest version is v1.5 (v1.51 for the expansion)

Skip intro videos[edit]

Edit config file[citation needed]
  1. Go to the configuration file(s) location.
  2. Open config.cfg (uoconfig.cfg for United Offensive).
  3. Change seta com_introplayed "0" to seta com_introplayed "1".
  4. Save the file.

Enable multicore support[edit]

Edit config file[citation needed]
  1. Go to the configuration file(s) location.
  2. Open config.cfg (uoconfig.cfg for United Offensive).
  3. Change seta r_smp "0" to seta r_smp "1".
  4. Save the file.


May not be relevant for digital re-release versions (it's already enabled).

German Language Fix[edit]

Takes the Nazi dialogue from the German release of the game and patches it over the other localizations' German dialogue. This fixes both some broken phrases and syncing/cutoffs of the dialogue.

Multiplayer is capped at 91 FPS by default.

Widescreen resolution[edit]

The game does not automatically adjust the aspect ratio to match widescreen resolutions.
Set resolution and aspect ratio[citation needed]
  1. Go to the configuration file(s) location.
  2. Edit config.cfg, config_mp.cfg, uoconfig.cfg, or uoconfig_mp.cfg.
  3. Set seta r_mode to seta r_mode -1 to enable custom resolution.
  4. Set seta r_customheight and seta r_customwidth to the resolution you want.
  5. Set seta r_customaspect to the aspect ratio (e.g. 1.6 for 16:10 1.7 for 16:9). Divide the resolution's width by height to calculate aspect ratio decimal.
  6. Change seta cg_fov "XX" to the FOV you want.
  7. Save your changes and close the file.
  8. Make the file read only, if needed.


If your monitor turns darker in fullscreen and the game doesn't respond to brightness settings, you can fix it with setting r_overBrightBits from 1 to 0
If your monitor turns very bright when attempting to Alt+Tab out of the game, you can fix it with setting r_ignorehwgamma from 0 to 1
If the intro and ending videos have audio but no video after this fix, you can view these files externally by extracting them from localized_english_pak0.pk3.

Field of view (FOV)[edit]

Use CoDUO FoV Changer for multiplayer.
Change FOV in SP[citation needed]
  1. Go to the configuration file(s) location.
  2. Edit config.cfg or uoconfig.cfg.
  3. Change seta cg_fov "XX" to the FOV you want.
  4. Save your changes and close the file.

Frame rate (FPS)[edit]

Use launch parameter[citation needed]

Use the command line argument +set com_maxfps X or console command /com_maxfps X, where X is your desired frame rate cap.

Edit your config

Look for seta com_maxfps X in your config file and set X (0 by default, which is uncapped) to your preferred value.

Keyboard and mouse State Notes
Software, such as the Logitech Gaming Software, is required to map controls to a mouse's side-buttons or any other additional buttons. For Steam, you will need the .exe's TestApp2620s.exe and TestApp2620m.exe, in addition to CoDSP.exe and CoDMP.exe to make a workable profile. For United Offensive, you will also need to look for CoDUOSP.exe and CODUOMP.exe.

Issues fixed[edit]

Buffer Overrun error on start-up[edit]

Game may display a black screen and error message on some cards. Seems to primarily affect those with Intel HD cards, and occurs more commonly with the United Offensive expansion.
Rename executable[citation needed]
  • Rename the executable you need to mohaa.exe and launch the game.
Use Nvidia card[citation needed]
Users with Nvidia Optimus can set the CoD .exes to use their dedicated Nvidia GPU instead of the integrated card- fixing the crash.
  1. Open Nvidia Control Panel.
  2. Go to Manage 3D Settings > Program Settings.
  3. Add the CoD executables and set the preferred graphics processor for each to 'High-performance NVIDIA processor'.

Mouse lag while aiming down sights[edit]

Edit the CFG[5]

Open the cfg file and change the seta cg_nopredict "1" to seta cg_nopredict "0", or type in the command in the console cg_nopredict "1".
