ATI Card Users can’t play in full screen:
We proposed this solution that sometimes solved the issue:
1. Enter the file 'PDC-Live'. This file should be located where you saved the game. The default path is usually:
2. Search for the "GraphicSettings.ini" file
3. Please change the following in this file:
Displaywidth = 1280
Displayheight = 800
Windowed = 1
4. Start the game in window mode.
5. After the game has started, change the resolution in the options menu to your preferred settings.
