Hello everyone.

I don't know how many of you know this but there are few launch parameters/commands for Battlefield 3 that allow you, for example, to launch the game in borderless mode. There are few different ways to add these parameters but if you want to play online you have to modify some Battlelog values.

So I was wondering what if BBLog have the options to add (or maybe just enable?) these launch parameters?

Sorry for the late reply. Anyways this is how it works normally.

Or you can just use the old desktop shortcut method. But using these ways the game will launch in singleplayer mode.
So if you want to launch it in multiplayer mode you have to modify some Battlelog values. This is how I do it.

I open the Chrome Dev Console (F12) and then I edit this:
launcher.userSettings[2]["commandLine"][1]
These are the default command lines:
-webMode MP -Origin_NoAppFocus -onlineEnvironment prod
Then I just another command lines and it works.

List of command lines that I know and should work:
-alwaysOnTop
-lowPriority
-noBorder
-noResize
-noTaskbar
There are definitely others but they either don't work or I don't how they work.

In the Battlelog/game code, there are a lot of info there. Anyways it seems with the today Battlelog update if you write the launch command using Origin it works for multiplayer too. So I guess the isn't needed anymore. I don't think there's a way to resize or center it, at least I haven't found it.

I already knew that, since the E3/alpha/pre-alpha or whatever it was. This thread was mainly for BF3 which has this option but it didn't work online before the latest Battlelog web plugin update.

Question: If you change "-onlineEnvironment" from "prod" to "dev", works? :P

Dunno. Never changed that.

Anyways I think this thread is now out of place in this section.
