Essential improvements[edit]


The fan patch creates a Windows NT-compatible executable file called ig2nt.exe. This should be the target of any shortcuts.

Running on Modern Systems[edit]

This game runs well with dgVoodoo 2.55.4 in 1080p resolution with anti-aliasing. You must set these in dgVoodoo and leave the game's resolution on 1024x768. This method avoids the black video bug.

Issues unresolved[edit]

Blank cutscenes[edit]

  • Many cinematics in the campaigns play only the sound (most notably the introductions).

Multiplayer compatibility[edit]

  • Multiplayer. But the guide linked earlier mentions it's possible if you ensure windows firewall is disabled. Apparently multiplayer will work with any of the four disks.

Issues fixed[edit]

Game crashes on non-4:3 resolutions[edit]

The game will crash on certain screens (fleet info, design, scenario select, etc.) if the display aspect ratio isn't 4:3 in the ig2.ini file.
Modify ig2.ini[citation needed]
  1. Go to the installation folder.
  2. Open ig2.ini.
  3. Find the line containing Video mode and modify it so a 4:3 resolution is specified. Example:
    Video mode = 1024x768x32
  4. Save and close the file.


Perform this step again whenever setup.exe is run.

Stutter on multi-core systems[edit]

Modify the game's shortcut target[citation needed]
  1. Right-click on the game shortcut.
  2. From the pop-up menu which appears, select Properties.
  3. Change the value of Target: to %WINDIR%\System32\cmd.exe /C START "Imperium Galactica 2" /normal /affinity 1 "C:\Program Files (x86)\Digital Reality\Imperium Galactica 2\ig2nt.exe"
  4. Click the OK button.


This fix assumes the patches are installed.
The new value for Target: assigns the game the first logical core, core 0. To use another processor, change /affinity 1 to another value, such as /affinity 2 to use the second logical core, core 1.

Game hangs on loading campagin[edit]

The game sometimes hangs if it needs to change disks to load a specific campaign.
Insert the correct game disc before selecting a campaign[citation needed]
