1280x1024 support in Battlefield 2 demo
This info was found on another forum and hasn't been tested but , I'm told it works.
Start BF2 with a shortcut with the following switch:
"[driveletter]:\Program Files\EA GAMES\Battlefield 2 Demo\BF2.exe" +menu 1 +fullscreen 1 +szx 1280 +szy 1024
This works with widescreen resolutions as well as 4x3(ish) aspect ratio stuff, I'm currently running 1920x1200 without a problem. Smile
"[driveletter]:\Program Files\EA GAMES\Battlefield 2 Demo\BF2.exe" +menu 1 +fullscreen 1 +szx 1920 +szy 1200
