Startup Parameters Config File

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

Note

⚠

NOTE: low level parameters are NOT supported.

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

• -cpuCount
• -malloc
• -exthreads
• -maxMem=
• -profiles= (unconfirmed, but seems to not work for Arma 3)

The reason is those need to be initialized before any file operations are done.

Location

Inside game folder

Naming

Depending on game:

• 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";
};

Post build 86060

Location

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.

Format

-startupParameter
-startupParameter2=value1;value2
MissionFileToOpenInTheEditor

Example

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