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 your language.

Play German Version in English

adds the English language files to the German version which does not offer any other language.

Widescreen resolution

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

Use United Fronts

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 resolution you want. 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 your changes and close the file. Make the file read only, if needed. Notes 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 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 is stretched. Lower vertical FOV at wider aspect ratios (Vert-). 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

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 FOV you want. Save your changes and close the file. To maintain identical vertical FOV to the 4:3 FOV at 16:9 resolutions, use 106. At 21:9 resolutions, use 121.

Frame rate (FPS)

In order for any of the fixes to work, Vsync needs to be turned off from the game's settings if your 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 your desired frame rate cap.

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

Remove 91 FPS cap in multiplayer
Look for seta com_maxfps 85 in your config_mp.cfg or uoconfig_mp.cfg file and set 85 to 0. Notes When framerate reaches over 900 you may experience connection issues with a "Connection Interrupted" notification.

Input

Keyboard and mouse	State	Notes
Remapping		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, 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 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]
Users with Nvidia Optimus can set the CoD .exes to use their dedicated Nvidia GPU instead of the integrated card- fixing the crash. 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'.

Level geometry visible behind fog

Edit the CFG
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 "0"

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".

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, you'll need a 2 GB card to play at 1080p resolution

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 CoD 1's campaign.
