Collected around some tips to enhance your
Battlefield 2 demo experience;
EA has a winner coming, expect huge ratings and awards around. All the tips below don't require any hacking and can be done by a mildly expert user.
1) Intro removal
go to EA GAmes/battlefield 2 demo/mods/bf2/movies and move somewhere else or rename (or even delete) the demo_*.bik EA.Bik and Nvidia.Bik
not really generous versus people that brought the demo but undoubetly saves load time.
2) 1280x1024 resolution
change game shortcut to "bf2.exe" +menu 1 +fullscreen 1 +szx 1280 +szy 1024
