Essential improvements


1.0 update adds an additional Multiplayer map, Hangar.
All Digital versions and retail version in the "Fan Favorites 1" collection already have this patch installed.

Republic Commando Fix

A community mod patch that provides extra graphical fixes and other features for modern systems.

Fixes some graphical issues, particularly bump mapping issues with modern graphics cards that previously caused a crash.
Adds widescreen/4K support, with an customizable FOV slider.
Adds an optional FPS limit to deal with issues like the high mouse sensitivity in menus or the helmet shake.
Defaults game to English for workaround see Game is in the wrong language.
Additionally, the mod comes with:
  • Restored multiplayer features by providing an alternative master server address.
  • A custom game executable (CT.exe).
  • The Unreal Code Compiler executable (UCC.exe), due to not having one within the game.
  1. Download and extract all files.
  2. Copy all files to <path-to-game>\GameData\System.

Set game framerate in game options to 30 or 60 in frames setting.


Starting via CT.exe will automatically enable the fixes (if the Mod.dll is present).

Issues fixed

Game crashes or displays odd artifacts[6]

This is a common problem, especially on ATI/AMD cards.
Intel HD Graphics are unaffected by this bug and can display the bumpmapped graphics natively.
Use Republic Commando Fix
Set Bump mapping to Low
Use d3d8to9

Error with Steam

If you get an error message saying, "Failed to detect Steam", "Problem starting up Steam", or something similar, try restarting Steam. If that does not work, try one of the following solutions

Set Template:SWRepublicCommando.exe to run in compatibility mode for Windows XP SP3.[citation needed]
Copy Steam.dll to game executable's directore[citation needed]
  1. Go to <Steam-folder>.
  2. Copy steam.dll to <path-to-game>\GameData\System.
Delete Steam ClientRegistry.blob file[citation needed]
  1. Go to <Steam-folder>\steam.
  2. Delete ClientRegistry.blob file.

Stretched HUD on widescreen resolutions

Use Widescreen HUD Fix v1.3
Made to work with 16:9 aspect ratio.
  1. Download the fix linked above.
  2. Go to <path-to-game>\GameData\Textures
  3. Replace the original HUDTextures.utx with the fixed one.


Can only be used if Bump mapping is set to Low.

3D & EAX never sets and/or saves with Creative/X-fi sound card

Use PAX custom Creative drivers
In Windows Vista and later, if the game refuses to set 3D Audio and EAX even with UseDefaultDriver=False and a checked OpenAL setup then custom "PAX" drivers for X-fi and other Creative audio cards are needed.
  1. Download this (alternatively this) file and install it.
  2. Make sure UseDefaultDriver=False is set in System.ini and the latest OpenAL is installed.

Game is in the wrong language

Modify System.ini to change the language
  1. Go to <path-to-game>\GameData\System.
  2. Open System.ini with any text editor.
  3. Find the line Language=xyz and change xyz to det for German, est for Spanish, frt for French, int for English, itt for Italian, pol for Polish and rus for Russian.

High FPS Issues

Use Republic Commando Fix
Limit the framerate to 60 FPS[citation needed]
Enable Vsync
  1. Download d3d8to9.
  2. Copy d3d8.dll to <path-to-game>\GameData\System.
  3. Enable Vsync in Graphics options and set monitor on 60hz.
