Duke Nukem: Manhattan Project

The Steam version has native widescreen support but the FOV is Vert-. These steps set the resolution for all versions and also fix the FOV.

1. Go to \duke\base\ and open config.cfg with a text editor.
2. Add the line uset g_cam_fov "90" (replace 90 with the horizontal FOV you want; the default is 50)
3. Find the line uset r_mode
4. Change the height and width (e.g. 1024x768) to the value you want.
5. Save your changes and close the file.
6. Make the file read-only (this prevents the FOV change being removed when you exit the game).

All 2D elements are stretched from 4:3. All 3D elements have the correct aspect ratio. The FOV specified is used for both gameplay and real-time cutscenes (2D elements during real-time cutscenes are stretched).
