Widescreen resolution

Modify the game registry keys[4]
  1. Navigate to the Configuration file(s) location using RegEdit.
  2. Change the ScreenHeight and ScreenWidth registry keys to the desired width and height.


On 64-bit versions of Windows, the configuration files may be in a different location if the game is not run in Administrator Mode.
See the Game data article or the Configuration file(s) location tooltips and notes for more information.


Use launch arguments
  • For windowed mode, Use the launch argument -window.
  • For borderless fullscreen windowed mode, use -window -noBorder.


For standard windowed mode, the game must be set to less than the screen resolution. Otherwise, the game will crash.
Alternatively, use the borderless command.

Issues fixed

Black screen/game window not appearing in Re-release

Some users may find that the game window will stop rendering correctly as the video intros end, with only the desktop visible as the menu is supposed to appear.
The issue appears to be an incompatibility with nGlide.[5]
Remove and/or replace nGlide[5]
  1. Remove or move the following files:
  • glide.dll, glide2x.dll, and glide3x.dll (nGlide related DLLs)
  • nglide_config.exe (nGlide configurator)
  • 3Dfx (folder, contains a DLL that links 3DFX OpenGL support to nGlide)
Optionally, the following files can be removed as well:
  • nglide_readme.txt (readme file for nGlide)
  • 3DfxSpl.dll, 3DfxSpl2.dll, and 3DfxSpl3.dll (3DFX animated splash screens)


After removing these files, the game may default to Software mode. This can be changed in options. The OpenGL renderer(s) are recommended.
3DFX-enhanced OpenGL mode may be unusable after applying this fix. If desired, it can be restored using dgVoodoo 2; otherwise, standard OpenGL will still be available.

Severe Lag in Menus

Use OpenGL rendering[citation needed]
Set launch arguments

Run the game with the following launch arguments: /nofastfe /noglddraw

Enabling OpenGL rendering on Windows 8 and later

OpenGL rendering can solve severe lag problems in menus. However, NT4 compatibility mode is required.
NT4 compatibility mode is no longer offered by default for Windows 8 and 10.
Restoring NT4 Compatibility Mode
  1. Download the Homeworld hardware acceleration fix to apply NT4 compatibility mode.
  2. Download the zip file and extract its contents.
  3. Follow the instructions in the readme.txt file.

Game runs on wrong screen (multi-monitor setup)

Use Windows key shortcuts to move the window

Use Win+ Shift+ or Win+ Shift+ to move the game to another window.


This may cause the game window to render incorrectly/off-center from the screen, or cause the mouse cursor to be caged to the wrong monitor.
Pressing Alt+Tab and returning to the game should fix mouse cursor bugs.
Change resolutions once to fix off-center screens.
This fix should only be necessary once.

The following command-line parameters may improve quality on newer systems, or enable extra functionality:
Parameter Description
/triple Enables OpenGL triple buffering, improves graphical quality and removes flickering at higher resolutions. Use unless it causes problems.
/enable3DNow Enables the 3DNow processor instruction set if available. Use unless it causes problems.
/enableSSE Enables the SSE processor instruction set if available. Use unless it causes problems.
/disableAVI Disables the intro movies when the game starts.
/nofastfe Disables the fast graphical frontend. Use this only when having graphical problems like flickering
/noglddraw Don't use DirectDraw to setup OpenGL renderers. Try this is you're having problems getting OpenGL to work.
/safeGL Don't use possibly buggy optimized features of OpenGL for rendering. Try this if you're having problems getting OpenGL to work.
/heap BYTES Allows the game to use up to BYTES bytes RAM for the heap since by default the game isn't allowed to use much. 256 MB should suffice: /heap 268435456 but if you have more, try raising it to 1 GB: /heap 1073741824
A list of all recognized command line options (can be viewed by passing an invalid option):
    /heap <n> - Sets size of global memory heap to [n].
    /prepath <path> - Sets path to search for opening files.
    /CDpath <path> - Sets path to CD-ROM in case of ambiguity.

    /enableSSE - allow use of SSE if support is detected.
    /forceSSE - force usage of SSE even if determined to be unavailable.
    /enable3DNow - allow use of 3DNow! if support is detected.

    /dsound - forces mixer to write to DirectSound driver, even if driver reports not certified.
    /dsoundCoop - switches to co-operative mode of DirectSound (if supported) to allow sharing with other applications.
    /waveout - forces mixer to write to Waveout even if a DirectSound supported object is available.
    /reverseStereo - swap the left and right audio channels.

    /rasterSkip - enable interlaced display with software renderer.
    /noBG - disable display of galaxy backgrounds.
    /noFilter - disable bi-linear filtering of textures.
    /noSmooth - do not use polygon smoothing.
    /noCPV - do not use vertex CPV.
    /nilTexture - don't ever load textures at all.
    /stipple - enable stipple alpha with software renderer.
    /noShowDamage - Disables showing ship damage effects.

    /safeGL - don't use possibly buggy optimized features of OpenGL for rendering.
    /triple - use when frontend menus are flickering madly.
    /nodrawpixels - use when background images don't appear while loading.
    /noswddraw - don't use DirectDraw for the software renderer.
    /noglddraw - don't use DirectDraw to setup OpenGL renderers.
    /sw - reset rendering system to defaults at startup.
    /noFastFE - disable fast frontend rendering.
    /fullscreen - display fullscreen with software renderer (default).
    /window - display in a window.
    /noBorder - no border on window.
    /640 - run at 640x480 resolution (default).
    /800 - run at 800x600 resolution.
    /1024 - run at 1024x768 resolution.
    /1280 - run at 1280x1024 resolution.
    /1600 - run at 1600x1200 resolution.
    /device <dev> - select an rGL device by name, eg. sw, fx, d3d.
    /nohint - disable usage of OpenGL perspective correction hints.
