German Language Fix

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.

When using a language different than English, rename the files localized_english_pakuo03 to the one corresponding to the desired language.

Ray tracing (RT)

Widescreen resolution

The game does not automatically adjust the aspect ratio to match widescreen resolutions.

Use United Fronts[citation needed]

Right click your game in your steam library and go to properties, add this line or your custom resolution and fov value to the command line, +set r_mode -1 +set r_customwidth 2560 +set r_customheight 1440 +set cg_fov 90

Set resolution and aspect ratio[citation needed]

Go to the configuration file(s) location. Edit config.cfg, config_mp.cfg, uoconfig.cfg, or uoconfig_mp.cfg. Set seta r_mode "0" to seta r_mode "-1" to enable custom resolution. Set seta r_customheight and seta r_customwidth to the desired resolution. 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. Save the changes and close the file. Make the file read only, if needed. Notes If the monitor turns darker in fullscreen and the game doesn't respond to brightness settings, fix it by setting r_overBrightBits from 1 to 0. If the monitor turns very bright when attempting to Alt+Tab ↹ out of the game, fix it with setting r_ignorehwgamma from 0 to 1. If the intro and ending videos have audio but no video after this fix, view these files externally by extracting them from localized_english_pak0.pk3. Windows scaling of applications can cause the resolution to not be applied correctly. Go to the properties of the executable and under compatibility change the high DPI override setting to be performed by application. HUD and menus are stretched. Vert-: Lower FOV at aspect ratios wider than 4:3. Increase FOV to compensate, see Field of view (FOV).

Field of view (FOV)

FOV adjustment is necessary at wider aspect ratios than 4:3.

Use CoDUO FoV Changer for multiplayer.

Use United Fronts[citation needed]

Change FOV in SP[citation needed]
Go to the configuration file(s) location. Edit config.cfg or uoconfig.cfg. Change seta cg_fov "XX" to the desired FOV. Save the changes and close the file. Notes The Kar98k has a bug where it shows a ghost bullet when the FOV is above 80. Use the kar98k fov fix to fix it.

Frame rate (FPS)

In order for any of the fixes to work, Vsync needs to be turned off from the game's settings if the screen's refresh rate is less than the required FPS, which is the case most of the time. The setting for Vsync is listed as "Sync Every Frame" under the Performance tab in the game Options and needs to be set to "No".

Use launch parameter[citation needed]
Use the command line argument +set com_maxfps X or console command /com_maxfps X, where X is the desired frame rate cap.

Edit config.cfg/uoconfig.cfg[citation needed]
Look for seta com_maxfps X in config.cfg or uoconfig.cfg and set X (0 by default, which is uncapped) to the preferred value.

Remove 91 FPS cap in multiplayer[citation needed]
Look for seta com_maxfps 85 in config_mp.cfg or uoconfig_mp.cfg, and set 85 to 0. Notes When framerate reaches over 900, the player might experience connection issues with a "Connection Interrupted" notification.

For Steam, the executables TestApp2620s.exe and TestApp2620m.exe are needed, in addition to CoDSP.exe and CoDMP.exe to make a workable profile. For United Offensive, look for CoDUOSP.exe and CODUOMP.exe.

Issues unresolved

Water reflections rendering is broken on AMD Graphics

On AMD Radeon GPUs running Adrenalin 22.7.1 (from July 2022) and later, the reflective water effect is broken due to the removal of the OpenGL extension GL_ATI_fragment_shader, causing the game to only render the basic non-reflective water textures. Since the removal was part of AMD's overhaul of their OpenGL renderer, GL_ATI_fragment_shader extension is considered deprecated and the company has no plans to add support of it back in the foreseeable future.

The revamped fragment shader extension, GL_ARB_fragment_shader, is fundamentally different from GL_ATI_fragment_shader and is not considered as a replacement.

Roll back AMD Radeon driver to Adrenalin 22.6.1 or earlier.
AMD Adrenalin 22.6.1 and earlier drivers are not available on Radeon RX 7000 Series graphics cards and newer.

Issues fixed

Buffer Overrun error on start-up

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 mohaa.exe and launch the game.

Use Nvidia card[citation needed]
Open Nvidia Control Panel. Go to Manage 3D Settings > Program Settings. Add the CoD executables and set the preferred graphics processor for each to 'High-performance NVIDIA processor'. Notes Users with Nvidia Optimus can set the CoD .exes to use their dedicated Nvidia GPU instead of the integrated card- fixing the crash.

Level geometry visible behind fog

Edit the CFG[citation needed]
Open config.cfg and replace the value seta r_fastsky "0" with seta r_fastsky "1". Notes The problem is caused by the detailed skybox being visible behind the fog. Therefore, this fix replaces the detailed skybox with a basic grey skybox, which might look strange especially during nighttime missions. However, the solution works well for "Festung Recogne".

Mouse lag while aiming down sights

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

Mouse stuttering/skipping

Download RInput
Create a shortcut to RInput.exe. Right-click the newly created shortcut, go to Properties, then add a space followed by "CoDSP.exe" without the quotation marks in the Target box (e.g. "...\RInput 1.44\RInput.exe" CoDSP.exe). Run Rinput through the shortcut before or during the game. Note that the executable name is case sensitive.

Stuttering while shooting

Edit the configuration file
Open the configuration file and change the seta r_maxEntLights "8" to seta r_maxEntLights "4". If stuttering persists, reduce further to seta r_maxEntLights "0". Notes: seta r_maxEntLights "0" will introduce visual glitches when firing in-game weapons.

Frequent crashes at particular points in the campaign

Lower World Dynamic Light Quality
In the in-game options, under 'Performance' set 'World Dynamic Light Quality' to "Fastest".

Quick-saving crashes United Offensive Expansion Pack

Game displays error message "recursive error after: Hunk_AllocateTempMemory: failed on 1048592, needs 836624"

Edit the configuration file
Open uoconfig.cfg and replace value seta com_hunkmegs "128" with seta com_hunkmegs "256".

Recorded game footage appears too dark

When recording game footage using software such as OBS Studio, AMD ReLive, or Nvidia ShadowPlay, recorded footage appears too dark regardless of driver or app settings.

Edit the configuration file
Open the configuration file and set the following values: seta r_overBrightBits "0" and seta r_ignorehwgamma "1".

Run game in Windowed mode

Mods

Extreme Mod 2/Lite 2013

A mod which adds new sounds, textures and more.

The original site no longer works. Here are the direct download links: Extreme Mod 2, Lite 2013.

HD Texture Enhancement

Upscales all the Textures in the game up to 4x using ESRGAN.

Makes the environment a little more clarified on a big screen.

Only supports the base game.

Slightly washes texture details.

Crashes the game on Pathfinder, put zcod7.pk3 that contains a fixed set of textures for the level. Conflicts with skyboxes that come in a separate archive.

Noticeably increases video memory requirement, at least 2 GB of VRAM are needed to play at 1080p.

Any degree of anti-aliasing transparency in NVIDIA Control Panel will cause a bizarre parallax effect of multiple blended copies of a texture notably at an angle, which is especially noticeable with this mod. Best to completely disable it for the game for the best result.

Ultra Effects and Sounds

A mod that adds blood while also adding other effects in the game.

United Fronts

Mod for United Offensive. Adds new models, textures, weapons, and sounds, new missions, and the base game's campaign.
