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 or uoconfig.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 r_customaspect to the aspect ratio (e.g. 1.6 for 16:10). 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.


If your monitor turns darker in fullscreen and the game doesn't respond to brightness settings, you can fix it with 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 r_ignorehwgamma from "0" to "1"

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.

Keyboard and mouse Native 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'.
