Instructions

  1. Download cnc-ddraw.zip and extract it into your game folder
  2. Start the game

Note: If you use cnc-ddraw with a game that got its own windowed mode built in then make sure you disable the games own windowed mode first.

If you want to play in windowed mode then start the game once in fullscreen and then press Alt+Enter to enable the cnc-ddraw windowed mode (Or modify ddraw.ini without using Alt+Enter).

 

If the game starts but it doesn't work perfectly then open ddraw.ini and search for Compatibility settings, one of the settings will usually fix the problem.

 

Compatibility setting examples:

  • If there are problems on Alt+Tab then try to set noactivateapp=true - If it still doesn't work also try renderer=opengl or renderer=gdi.

  • If the game is running too fast then try to set maxgameticks=60 - If it's still too fast, try a lower value.

  • If windowed mode or upscaling are not working properly then try to set hook=2 and renderer=gdi.

  • If videos or other UI elements are invisible then try to set nonexclusive=true.

  • If some parts of the screen are being displayed diagonally then try to set fixpitch=true.

  • If the game is stuttering on a Freesync/G-Sync monitor then try to set minfps=-1.

 

If the game doesn't start at all or it's crashing, then please generate a debug log file and upload it.

 

Hotkeys

  • [Alt] + [Enter] = Switch between windowed and fullscreen mode
  • [Ctrl] + [Tab] = Unlock cursor
  • [Right Alt] + [Right Ctrl] = Unlock cursor
