Server parameter can be combined with addons & addonsDir parameters to start a server with local mods, which can be useful when testing addon before uploading it Workshop.
ArmaReforgerServer.exe -server "worlds/MP/MPTest.ent" -addonsDir "C:\MyModsDir" -addons MyCustomMod
client
-client starts up an RplSession in local client mode. The session tries to connect to the provided IP.
- Example #1
ArmaReforgerSteam.exe -client 127.0.0.1
- Example #2
- This will connect game to a locally hosted dedicated server and load the local MyCustomMod addon

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
rpl-timeout-ms
-rpl-timeout-ms sets the client/server timeout's value, in milliseconds.
- Example
ArmaReforgerServer.exe -rpl-timeout-ms 10000
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
AILimit
-aiLimit sets the top limit of AIs. No systems will be able to spawn any AIs when this ceiling is reached (through aiWorld.CanAICharacterBeAdded() - see also SCR_AIGroup and SCR_ChimeraAIAgent).
- Example
ArmaReforgerServer.exe -AILimit 32 ArmaReforgerServer.exe -AILimit 0 ArmaReforgerSteam.exe -AILimit 100 ArmaReforgerSteam.exe -AILimit 0
AIPartialSim
-aiPartialSim sets in how many batches before all AIs (as if in LOD0) will be processed.
- Example
ArmaReforgerSteam.exe -aiPartialSim 5
createDB
-createDB forces database file's regeneration. Useful after file directories changes, when some resources were moved elsewhere. Takes a few seconds upon start.
- Example
ArmaReforgerServer.exe -createDB
debugger
-debugger sets the script debugger to a specific address.
- Example
ArmaReforgerServer.exe -debugger 192.168.0.5
debuggerPort
-debuggerPort sets the script debugger to a specific port.
- Example
ArmaReforgerServer.exe -debuggerPort 1040

- Example
ArmaReforgerServer.exe -jobsysShortWorkerCount 4
jobsysLongWorkerCount
-jobsysLongWorkerCount sets the number of threads working on long jobs (jobs that can span multiple iterations of update loop). Value is limited to at most number of CPUs.
- Example
ArmaReforgerServer.exe -jobsysLongWorkerCount 4
keepNumOfLogs

- 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
logFS
-logFS logs every F'ile System's 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 be used with caution for debug purpose only.
- Example
ArmaReforgerSteam.exe -logFS
logLevel
-logLevel allows for different log levels. Each level includes the ones below it (e.g error includes error and fatal). Possible values range from normal (where everything is logged) to fatal (where only extreme issues are logged):
