We already have some limited info about this game...
Confirmed Game Solutions » Solution: Star Wars : Empire at War Demo [Partial]
Surround & Eyefinity Media » Star Wars: Empire at War + Expansion
...but seeing how older threads are incomplete or outdated, and how ws support in EAW is limited, yet complex, I decided to write a new (and hopefully definitive) solution from scratch.
Method:
The game supports all res's natively, simply select your desired resolution and tick the Widescreen checkbox.
Display settings are saved in the registry under HKCUSoftwarePetroglyphStarWarsProfilesProfile0Player
Screen change:
Land mode: 16:9 is Hor+, all other ARs are 16:9 squished/stretched.
Space mode: 16:9 is vert-, all other ARs are 16:9 squished/stretched.
Current version is 1.05, partial Hor+ solution was introduced in v1.02.
Further details and dead ends:
Some limited modding of the cameras is possible, but will not really improve support. All moddable FOV values refer to a vertical FOV, so all you can do is "dolly out" and make the game look even worse...
To fiddle with the VFOV, open the following file in FinalBIG 0.4+:
C:Program FilesLucasArtsStar Wars Empire at WarGameDataDataConfig.meg (make a backup copy!)
and edit DATAXMLTACTICALCAMERAS.XML
In the registry, there's a WidescreenAspectRatio key in
HKCUSoftwarePetroglyphStarWarsProfilesProfile0Player
but even if some genius can find the right value for 16:10 or Surround, it will only help in land combat mode... The rest will remain Vert-.
