.....and fill ya boots :p

Well there is a part in the manual regarding the Late war sensors
That much I do know

GWX - Lite Harbor Traffic - gives reduced traffic in home ports only for those with computer at the lower end of the rage

GWX - 16km Atmosphere - Increases visual range to 16KM from the default 8KM - again will add extra load to your PC and if you can see 16KM so can the enemy

GWX - Integrated Orders - means you can use the mouse to do more controls instead of the keyboard
( I think lol I always get that arse about face )

GWX - Fix French - enables French language for those that speak the lingo - replaces all English in the game

GWX - No Medals on Crew - Is what it says it is - your crew wont wear medals

GWX - Captain America's Officer Icons - Is a different set of Officer Icons bottom left of HUD

Is that all of them ?
Dont have 1.03 so cant say for sure
