I propose the following as the best widescreen solution for Call of Duty. It contains precise FOV recommendations plus a new method to avoid the Activision and Infinity Ward intros that do not display anyway.
This applies to Single Player only. Make all changes in the following file using WordPad or Notepad. Be sure to do a File>Save when you're finished.
C:\Program Files\Call of Duty\Main\config.cfg
For a 16:9 Aspect Ratio Resolution:
seta cg_fov "96.4183" (Changes FOV from default of 80.)
seta r_mode "-1" (Allows custom resolutions to work.)
seta r_customheight "720" (Enter your own "Y Axis" resolution.)
seta r_customwidth "1280" (Enter your own "X Axis" resolution.)
seta com_introplayed "1" (Skips the Activision and Infinity Ward intros. Otherwise, you'll hear sound only.)
For a 16:10 Aspect Ratio Resolution:
seta cg_fov "90.3951" (Changes FOV from default of 80.)
seta r_mode "-1" (Allows custom resolutions to work.)
seta r_customheight "1200" (Enter your own "Y Axis" resolution.)
seta r_customwidth "1920" (Enter your own "X Axis" resolution.)
seta com_introplayed "1" (Skips the Activision and Infinity Ward intros. Otherwise, you'll hear sound only.)
In Multiplayer you can force custom resolutions using the same settings, but it is impossible to increase the default FOV. It will always revert to 80. For this reason, I suggest playing multiplayer at a "normal" 4:3 resolution.
