Anisotropic filtering (AF)[edit]

  2. Go to [D3DDrv.D3DRenderDevice] section.
  3. Change ; LevelOfAnisotropy=1 to LevelOfAnisotropy=16.
  4. Save the file.

Input settings[edit]

In-game key map settings.
In-game key map settings.
Mouse sensitivity in menus is bound with sensitivity in game. Because of that, navigating menus may become difficult, if a player sets high mouse sensitivity or has a high DPI mouse. Setting the game to a higher resolution may be able to help mitigate this.[4]

Mouse acceleration[edit]

Edit config file[citation needed]
  1. Edit <path-to-game>\GameData\Save\Profile_<user-id>\User.ini.
  2. Go to [Engine.PlayerInput] section.
  3. To disable mouse smoothing set MouseSmoothingMode to 0.
  4. To change the strength of mouse smoothing, change MouseSmoothingStrength using a value between 0.0 (weakest smoothing) and 1.0 (strongest).
  5. To change mouse acceleration, change MouseAccelThreshold using a value between 0 (no acceleration) and 100 (full acceleration).

Mouse sensitivity[edit]

Edit User.ini[citation needed]
  1. Calculate your sensitivity for UT2004 on
  2. Edit <path-to-game>\GameData\Save\Profile_<user-id>\User.ini.
  3. Go to [Engine.PlayerInput] section.
  4. Change the value of MouseSensitivity= to the sensitivity you calculated.
  5. Edit <path-to-game>\GameData\Save\System.ini.
  6. Go to [WinDrv.WindowsClient] section.
  7. Change the values of both MouseYMultiplier= and MouseXMultiplier= to 0.4.
If the menu sensitivity is still too high, then halve both mouse multipliers and double your sensitivity.

Controller support[edit]

Enabling Gamepad[citation needed]
This fix a profile to be already created already by the game.
  1. Download this file and extract it.
  2. Open User (joystick).ini and copy all of its content.
  3. Open <path-to-game>\GameData\Save\Profile_<user-id>\User.ini remove its content and paste the content copied from User (joystick).ini in there.
  4. Save the changes.
  5. Open <path-to-game>\GameData\System\System.ini.
  6. Change UseJoystick=False to UseJoystick=True.
  7. Save the changes.
  8. Copy the Dinput.dll, Dinput8.dll, XInput1_3.dll and XInputPlus.ini from XInput Plus Files folder (that you have extracted) and paste them in <path-to-game>\GameData\System.

Controller sensitivity and axis inversion[edit]

Edit User.ini[citation needed]
This guide is written for the Controller support fix and it may not work with custom bindings.
  1. Edit <path-to-game>\GameData\Save\Profile_<user-id>\User.ini.
  2. Find a line JoyR=Axis aBaseX. Adjust the Speed value for your X-axis sensitivity. To invert the axis add type in a negative value (e.g. Speed=-690).
  3. Find a line JoyU=Axis aLookUp. Adjust the Speed value for your Y-axis sensitivity. To invert the axis add type in a negative value.

Issues fixed[edit]

Game crashes or odd artifacts appear[edit]

Bump Mapping Crash[8]

This is a common problem, especially on ATI/AMD cards. Setting Bump mapping to Low should solve the problem. You can also start the game with a DirectX-8-to-9 emulator or install a fan made graphics fix to resolve the crashes.

Intel HD Graphics are unaffected by this bug and can display the bumpmapped graphics natively.

Error with Steam[edit]

Steam error[citation needed]

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 deleting ClientRegistry.blob in the \Steam folder.

If it continues to not function correctly - it may work the first time after running Steam, then fail - then do the following:

  1. Go to <path-to-game>\GameData\System\
  2. Right-click SWRepublicCommando.exe and go to the Compatibility tab of Properties.
  3. Tick the Run this program as an Administrator box, as well as the box for XP compatibility at the top, and apply the changes.

Stretched HUD fix[edit]

Use a fixed HUDTextures.utx[citation needed]

This will correct the HUD for 16:9 resolutions.

  1. Download the Widescreen HUD Fix v1.3.
  2. Go to <path-to-game>\GameData\Textures\
  3. Replace the original HUDTextures.utx with the fixed one.

3D & EAX Never Sets with Creative/X-fi[edit]

Use PAX custom Creative drivers[citation needed]

In Vista and Win7 (possibly later OS's as well) if the game refuses to set 3D Audio and EAX even with "UseDefaultDriver=False" and a checked OpenAL setup then install the custom "PAX" drivers for X-fi and other Creative audio cards.

  1. Download [1] and/or [2].
  2. Install.
  3. Make sure "UseDefaultDriver=False" is set in system.ini and latest OpenAL is installed.
  4. Now 3D Audio as well as EAX 3 and 32 channels should stay set in the options menu after game restart.
