Ensure that you are running the latest drivers for your video card. Most of our games require support for pixel & vertex shader 2.0 or higher. More info.
If the main menu screen becomes corrupted or you find that you cannot input characters in the New Game screen, this is due to a conflict in some graphics settings between the game and your graphics card tools
Try the following:
Quit to Windows
Locate and delete the game's INI configuration file from the install folder. See KB7 and KB78
Restart the game. A new INI file will be created
Make your selections, but leave anti-aliasing and texture filtering at the defaults
Quit to Windows, and restart the game
If the above still doesn't work. Then in your graphic card's tool, try these settings. You can also create game specific profiles if your graphics card tool supports that.
Anti-Aliasing Mode to "Override Application Settings", then choose any options there
Anisotropic Filtering Mode to "Override Application Settings", then choose any options there
Reboot your computer for the above to take global effect.
