Resolution problem:

The game does not support widescreen resolution, you can only add it manually.

Just change the values of "FullscreenViewportX=" and "FullscreenViewportY=" in file "Swat4.ini" or "Swat4X.ini".

A list of all supported resolutions can be found in the link below.

GO

Elite Force modification supports current resolutions.

Multiple monitor fix:

Many people with more than one monitor have problems because of this.

Delete file "Swat4.ini" or "Swat4X.ini" and add startup options "-nointro" to file "Swat4.exe" or "Swat4X.exe".

If it did not help, disconnect one of the monitors.

Game won't start:

Delete file "Swat4.ini" or "Swat4X.ini".

Set compatibility options for "Swat4.exe" or "Swat4X.exe" to "Windows XP".

Start the game using "exe" files.

Remember that the game does not support high resolutions.
