I have everything max by default and when i try to play for the past week it says lost connection to server but it always worked fine.
The only tweak that fixed/reduced that for me, is to disable origin in-game for titanfall. Right click on origin titanfall icon, then game properties and from there check the box to disable origin in-game. A few other tweaks for faster/bugless menus is to add this command lines to titanfall(above the check box for origin in-game disable). -novid -nomenuvid 1 copy paste that there. it simply removes game intro videos and menu video ,but thats when the menus and burn card scroll speed take a huge boost. You 'll see for yourself ;-)
