Location can be defined with -par=parameterFileName startup parameter. If file extension is .par the formatting described previously is required. With any other extension (like .txt) a plain text is assumed, with one command line option per line. In both cases the file is preprocessed before parsing, allowing C++ style comments and #define-s to be used.

The startup parameters config file can be used to put startup parameters in, instead of specifying them in a shortcut/commandline.

⚠
Low level parameters are NOT supported:

.par file does not (and will not) support some low level parameters, namely:

  • -cpuCount
  • -malloc
  • -exthreads
  • -maxMem
  • -profiles (confirmed on Arma 3 version 1.66.139586, options does not work from parameter file)
  • -debug
The reason is those need to be initialized before any file operations are done.


Usage

-par startup parameter allows to specify the file. Whether using Plain Text Format or .par Format, the file is preprocessed before parsing, allowing C++ style comments and #defines to be used.

ⓘ
Before Arma 2: Operation Arrowhead v1.60.86060, only the .par format was supported.

Windows

-par won't work being passed by cmd as variable to quotes; a specific format must be applied: 

setlocal enableDelayedExpansion enableExtensions

set v=!v! "-profiles=!cd!\acc"
set v=!v! "-par=D:\par\startupParameters.txt"

start "" "D:\arma3\arma3.exe" !v!	&rem need "start" for closing cmd window;
timeout /t 1						&rem need for keeping game window (starting from logo) foreground after cmd window close;


Plain Text Format

  • The file extension must be anything but .par, otherwise the .par Format syntax will be assumed.
  • The file can be located either inside or outside of the game folder for organizational purposes.
  • The file must have one command line option per line.

Location

Location can be defined with -par=parameterFileName startup parameter.

Format

Whitespace is ignored. 

-startupParameter
-startupParameter2=value1;value2
MissionFileToOpenInTheEditor

Examples

Simple Example

-nosplash
-skipIntro
-world=none
-mod=Expansion;Expansion\beta;Expansion\beta\Expansion;@cwr2
"C:\arma2\Users\USERNAME\missions\MissionName.Desert_E\mission.sqm"

Host and Client

The following example allows you to launch two instances of the game with common startup parameters. One for hosting from Eden and another one as a client to test for locality issues.

base.txt 

-mod="!Workshop\@Mod1;!Workshop\@Mod2"
-skipIntro
-noSplash
-filePatching
-noSound
-noLand

host.txt 

#include "base.txt"
"C:\Users\USERNAME\Documents\Arma 3\missions\BIKI.VR"

client.txt 

#include "base.txt"
-name=ClientTest

.par Format

⚠
The .PAR file extension is apparently no longer read correctly on a dedicated server.

Location

At game directory's root.

Naming

Arma 2 Arma 2: Operation Arrowhead Take On Helicopters
ArmA2.par ArmA2OA.par TakeOnH.par

Format

class Arg
{
	startupParameter="-startupParameter"
	startupParameter2="-startupParameter2=value1;value2"
};

Example

class Arg
{
	nosplash="-nosplash";
	skipIntro="-skipIntro";
	world="-world=none";
	mod="-mod=Expansion;Expansion\beta;Expansion\beta\Expansion;@cwr2";
};
