Step 5: Setup Borderless Fullscreen Mode (Requires GenTool)

Generals and Zero Hour regularly crash when you attempt to Alt+Tab out of the game window. Enabling Borderless Fullscreen using the following instructions will make the game more stable.

  • If you are using Origin
    • Configure the game to run in windowed mode. Right click on Generals/Zero Hour in Origin
    • Click "Game Properties"
    • Navigate to the "Advanced Launch Options" tab
    • Type "-win" (without the quotes) into the command line arguments box
  • If you are using a Physical version of the game
    • Create a shortcut of the Generals (or Zero Hour) executable
    • Right click on the shortcut and select “Properties”
    • In the “Target” box at the end of the directory path (after the quotation mark) type "-win" (without the quotes)
    • Apply and Exit

Now launch the game.

  • Once in the main menu, configure your resolution in the options menu.
  • Press "Insert" on the keyboard to bring up GenTool's options menu (On laptops this is usually connected to the Fn key).
  • Navigate down the options in GenTool and change the Window Position to "FULL".

You should now have Generals running with borderless fullscreen, which is incredibly smooth and compatible with Alt+Tabbing!

Known Issues

Generals & Zero Hour Crash when Alt+Tabbing in Fullscreen Mode

If you run the game in Fullscreen (NOT Borderless Fullscreen) the game will sometimes crash when you attempt to Alt+Tab out of it. The fix for this is to use d3d8to9-wrapper, which improves compatibility and stability of the game significantly by converting all Direct3D 8-API calls and low level shaders to equivalent Direct3D 9 ones.

  1. Download the latest version of d3d8to9
  2. If you also use Gentool: rename the file from d3d8.dll to d3d8x.dll to make sure you don't overwrite Gentool.
  3. Place the file in the game directory of both Generals and Zero Hour.
  4. Play the game.

Zero Hour is Censored in Germany
