Startup Parameters – Arma Reforger

ⓘ

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

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

⚠

These parameters apply to the Server executable.

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

rpl-reconnect

-rpl-reconnect makes the replication try to reconnect instead of immediately raising connection failure.

⚠

Endless reconnection loop is designed for debug purposes only.

Example

ArmaReforgerServer.exe -rpl-reconnect

rpl-timeout-disable

rpl-timeout-disable disables client/server timeout.

⚠

If a connection stops responding, the server performance will start deteriorating until it will eventually run out of memory and crash. This parameter is strictly for debugging purposes.

Example

ArmaReforgerServer.exe -rpl-timeout-disable

rpl-timeout-ms

rpl-timeout-ms sets the client/server timeout's value, in milliseconds.

Example

ArmaReforgerServer.exe -rpl-timeout-ms 10000

rpl-validation-rdb-disable

-rpl-validation-rdb-disable disables the validation of clients resource database.

⚠

This should not be disabled in normal usage conditions. This is for development purpose only!

Example

ArmaReforgerServer.exe -rpl-validation-rdb-disable

rpl-validation-scr-disable

Disables the validation of clients scripts checksum.

⚠

This should not be disabled in normal usage conditions. This is for development purpose only!

Example

ArmaReforgerServer.exe -rpl-validation-scr-disable

rpl-validation-version-disable

Disables the validation of clients executable version.

⚠

This should not be disabled in normal usage conditions. This is for development purpose only!

Example

ArmaReforgerServer.exe -rpl-validation-version-disable

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

debugger

-debugger sets the script debugger to a specific address.

ⓘ

The default value is localhost.

Example

ArmaReforgerServer.exe -debugger 192.168.0.5

debuggerPort

-debuggerPort sets the script debugger to a specific port.

ⓘ

The default value is 1000.

Example

ArmaReforgerServer.exe -debuggerPort 1040

disableShadersBuild

-disableShadersBuild disables shaders generation.

Example

ArmaReforgerServer.exe -disableShadersBuild

generateShaders

-generateShaders forces shaders generation.

Example

ArmaReforgerServer.exe -generateShaders

log-rdb-checksum

-log-rdb-checksum enables logging detailed information about RDB checksum computation (GUID and path in order in which they are added to checksum) for RDB checksum issues debugging.

Example

ArmaReforgerSteam.exe -log-rdb-checksum

log-scr-checksum

-log-scr-checksum enables the logging of all script files used in compilation and their checksums.

Example

ArmaReforgerSteam.exe -log-scr-checksum

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

logFS

-logFS logs every read/write operation in filesystem.log. This option is very demanding and can produce a big file in a short time, so it is to use with caution for debug purpose.

Example

ArmaReforgerSteam.exe -logFS

noCrashDialog

-noCrashDialog skips Crash Reporter's dialog and automatically sends crash reports.

Example

ArmaReforgerSteam.exe -noCrashDialog

keepCrashFiles

-keepCrashFiles prevents Crash Reporter from cleaning crash files on successful crash sending.

Example

ArmaReforgerSteam.exe -keepCrashFiles

scriptAuthorizeAll

-scriptAuthorizeAll disables the security popup about RunCmd, RunProcess, KillProcess and (outside of profile directory) FileIO operations.

Example

ArmaReforgerSteam.exe -scriptAuthorizeAll

VMErrorMode

-VMErrorMode sets script VM's error reporting mode; possible values are:

• silent - silently continues
• log_only - logs the error then continues
• full - shows the VME dialog, logs the error, then clicking "ignore" continues execution
• fatal - logs the error then exits the game

Profiling

checkInstance

-checkInstance turns on script VM's memory allocations logging - see Script Profiling.

scriptExtProfiler

-scriptExtProfiler turns on script VM's support for external Script Profiling.

ⓘ

The External Profiler can also be enabled through the Diag Menu: Diag Menu > Statistics > Script prof. external set to true.

Example

ArmaReforgerSteam.exe -scriptExtProfiler
