Arma Reforger:Startup Parameters

ⓘ

Startup parameters' names are case-insensitive - e.g -logstats and -LogSTATS are identical.

General

addons

-addons takes a list of mod IDs (specified in their gproj files, without brackets) to be loaded on game start, separated by a comma ,.
Mods are searched in profile/addons, in <executableDir>/addons and in directories specified by -addonsDir (see below).

ⓘ

Mod IDs can be:

• GUIDs (preferred - found in .gproj)
• Project ID (found in .gproj)
• Sub-directory name (fallback solution)

Example

ArmaReforgerSteam.exe -addons 88037E46AD234C72,88037E46AD234C73

addonsDir

-addonsDir specifies additional directories in which the game must look for mods to load, separated by a comma ,.

ⓘ

By default, the game looks into:

• Documents/My Games/ArmaReforger/profile/addons
• <executableDir>/addons

⚠

It is recommended to use absolute paths to Mod directories even though the provided path can be relative to the executable location.

Example

ArmaReforgerSteam.exe -addonsDir D:\DownloadedMods

addonDownloadDir

-addonDownloadDir specifies where the game and the Workshop should download addons.

⚠

It is recommended to use absolute paths to Mod directories even though the provided path can be relative to the executable location.

Example

ArmaReforgerSteam.exe -addonDownloadDir D:\DownloadedMods

GPUAdapter

-GPUAdapter forces to use the graphic card at the provided index. GPU index can be found using DxDiag.

Example

ArmaReforgerSteam.exe -GPUAdapter 0

Window

window

-window starts the game windowed (fullscreen by default).

Example

ArmaReforgerSteam.exe -window

posY

-posX and -posY define the initial window position. They must be used with -window.
posX 0 is left of the screen,
posY 0 is top of the screen.

Workbench

⚠

These parameters apply to the Workbench executable.

packAddon

Main parameter used for addon packing.

When no directory is specified (by using packAddonDir), a directory from last session is used.

When packing an addon for the first time, a new directory is automatically created in the same dir as profile.

Example

ArmaReforgerWorkbench.exe -wbmodule=ResourceManager -packAddon

packAddonDir

-packAddonDirspecifies the output directory where resulting PAKs will be saved.

Example

ArmaReforgerWorkbench.exe -wbmodule=ResourceManager -packAddon -packAddonDir "D:\build\Green"

publishAddon

-publishAddon is main parameter used for addon publishing.

It should be used only for publishing addon updates, and not for the initial publish because data from last session are used to fill in the blanks.

It can be used on its own, in combination with packAddon or in combination with parameters starting with "publishAddon".

When no directory is specified (by using publishAddonDir) a directory from last session is used.

Example

ArmaReforgerWorkbench.exe -wbmodule=ResourceManager -publishAddon

publishAddonDir

-publishAddonDir specifies the pre-packed data directory (obtained by the -packAddon parameter above). When not specified, directory from the last session is used.

Example

ArmaReforgerWorkbench.exe -wbmodule=ResourceManager -publishAddon -publishAddonDir "D:\build\Green"

publishAddonVersion

-publishAddonVersion specifies the mod's version number. When not specified, newest version found on back-end is used and it's last digit is automatically incremented.

Example

ArmaReforgerWorkbench.exe -wbmodule=ResourceManager -publishAddon -publishAddonVersion "2.3.5"

publishAddonChangeNote

-publishAddonChangeNote is an optional parameter that specifies a note to the provided update.

Example

ArmaReforgerWorkbench.exe -publishAddonChangeNote "Fix shading"

publishAddonChangeNoteFile

-publishAddonChangeNoteFile is an optional parameter that specifies a note to the provided update through the provided file.

Example

ArmaReforgerWorkbench.exe -publishAddonChangeNoteFile "changelog.txt"

	Print("The TAG_DEBUG flag is defined.");
#else
	Print("The TAG_DEBUG flag is not defined.");
#endif

Example

ArmaReforgerWorkbench.exe -scrDefine TAG_DEBUG -scrDefine OTHER_FLAG
ArmaReforgerSteam.exe -scrDefine TAG_DEBUG -scrDefine OTHER_FLAG
ArmaReforgerServer.exe -scrDefine TAG_DEBUG -scrDefine OTHER_FLAG

• RplItemsC0: <int> = The number of streams open to the client at the time of reporting.

maxFPS

-maxFPS sets max FPS limit - useful for a server, or to force a client's max FPS.

ⓘ

Also works on clients, even though the Video Settings FPS limitation option is preferred.

Example

ArmaReforgerServer.exe -maxFPS 30

Network Tuning

nds

-nds Network Dynamic Simulation (nds) is a server feature that only streams in relevant replicated entities for each client. the provided value stands for diameter, or the number of cells which are being replicated - default is 2 in each direction. To turn the feature off use -nds 0. A higher diameter will result in a bigger networked view range, lower server performance.

Example

ArmaReforgerServer.exe -nds 1

nwkResolution

-nwkResolution defines what resolution Spatial Map cells should be set at in a 100..1000m range. Smaller resolution will result in less "pop-in" but lower networked view range. For high view range use high resolution, but small diameter.

Example

ArmaReforgerServer.exe -nwkResolution 500

staggeringBudget

-staggeringBudget defines how many stationary spatial map cells are allowed to be processed in one tick in 1..10201 range. If not set it uses "-nds" diameter. A lower number will limit how many cells the server has to process per tick, but increase the time it takes for a client to have all relevant entities streamed in, if the server experiences significant performance drops on spawning/teleporting then the number is set too high, if you the client experiences "pop-in" of replicated items then the number is set too low.

Example

ArmaReforgerServer.exe -staggeringBudget 5000

streamingBudget

-streamingBudget is the global streaming budget that is equally distributed between all connections. To decrement the budget, it uses the replicated hierarchy size of each entity that needs to be streamed in. It cannot go under 100 to prevent the system stalling. A lower number will limit how many entities the server has to process per tick, but increase the time it takes for a client to have that entity streamed in, if the server experiences significant performance drops on spawning/teleporting then the number is set too high, if the client experiences "pop-in" of replicated items then the number is set too low.

Example

ArmaReforgerServer.exe -streamingBudget 500

streamsDelta

-streamsDelta is a tool to limit the amount of streams being opened for a client in range 1..1000 (default 100). If the difference between 'the number of streams the server has open' and 'the number of streams the client has open' is larger than the NUMBER then the server will not open any more streams this tick. To be adjusted based on average client networking speed.

Example

ArmaReforgerServer.exe -streamsDelta 200

Debug

logAppend

-logAppend makes logs to not be emptied on game start, keeping the history.

Example

ArmaReforgerSteam.exe -logAppend

logLevel

-logLevel allows for different log levels. Possible values range from normal (where everything is logged) to fatal (where only extreme issues are logged):

• normal
• warning
• error
• fatal

Example

ArmaReforgerSteam.exe -logLevel warning
