Arma 3 Startup Parameters
| Variable | Function |
|---|---|
| ARMA3_PORT | Port to have dedicated server listen on |
| ARMA3_BEPATH | By default BattlEye will create BattlEye folder inside server profile folder. With bepath param it is possible to specify a custom folder |
| ARMA3_PROFILES | Path to the folder containing server profile. By default, server logs are written to server profile folder. If folder doesn't exist, it will be automatically created |
| ARMA3_BASIC_CFG | Selects the Server Basic Config file. Config file for server specific settings like network performance tuning |
| ARMA3_SERVER_CFG | Selects the Server Config File. Config file for server specific settings like admin password and mission selection |
| ARMA3_WORLD_CFG | Init Landscape by the given world config |
| ARMA3_NAME | Profile name |
| ARMA3_MODS | Loads the specified sub-folders for different mods. Separated by semi-colons. Absolute path and multiple stacked folders are possible |
| ARMA3_SERVER_MODS | Loads the specified sub-folders for different server-side (not broadcasted to clients) mods. Separated by semi-colons. Absolute path and multiple stacked folders are possible |
| ARMA3_BANDWIDTH_ALG | Uses a new experimental networking algorithm that might be better than the default one |
| ARMA3_IP | Command to enable support for Multihome servers. Allows server process to use defined available IP address |
| ARMA3_AUTOINIT | Automatically initialize mission just like first client does |
| ARMA3_LOAD_MISSION_TO_MEMORY | Server will load mission into memory on first client downloading it. Then it keeps it pre-processed pre-cached in memory for next clients, saving some server CPU cycles |
| ARMA3_NOSOUND | Disables sound output |
| ARMA3_NOSPLASH | Disables splash screens |

Basic Configuration
| Variable | Function |
|---|---|
| ARMA3_LANGUAGE | Language settings |
| ARMA3_ADAPTER | Adapter settings |
| ARMA3_3D_PERFORMANCE | 3D Performance settings |
| ARMA3_RESOLUTION_W | Resolution width settings |
| ARMA3_RESOLUTION_H | Resolution height settings |
| ARMA3_RESOLUTION_BPP | Resolution BPP settings |
| ARMA3_MIN_BANDWIDTH | Bandwidth the server is guaranteed to have (in bps). This value helps server to estimate bandwidth available. Increasing it to too optimistic values can increase lag and CPU load, as too many messages will be sent but discarded. Default: 131072 |
| ARMA3_MAX_BANDWIDTH | Bandwidth the server is guaranteed to never have. This value helps the server to estimate bandwidth available. |
| ARMA3_MAX_MSG_SEND | Maximum number of messages that can be sent in one simulation cycle. Increasing this value can decrease lag on high upload bandwidth servers. Default: 128 |
| ARMA3_MAX_SIZE_GUARANTEED | Maximum size of guaranteed packet in bytes (without headers). Small messages are packed to larger frames. Guaranteed messages are used for non-repetitive events like shooting. Default: 512 |
| ARMA3_MAX_SIZE_NONGUARANTEED | Maximum size of non-guaranteed packet in bytes (without headers). Non-guaranteed messages are used for repetitive updates like soldier or vehicle position. Increasing this value may improve bandwidth requirement, but it may increase lag. Default: 256 |
| ARMA3_MIN_ERROR_TO_SEND | Minimal error to send updates across network. Using a smaller value can make units observed by binoculars or sniper rifle to move smoother. Default: 0.001 |
| ARMA3_MIN_ERROR_TO_SEND_NEAR | Minimal error to send updates across network for near units. Using larger value can reduce traffic sent for near units. Used to control client to server traffic as well. Default: 0.01 |
| ARMA3_MAX_CUSTOM_FILE_SIZE | Users with custom face or custom sound larger than this size (bytes) are kicked when trying to connect. |
| ARMA3_MAX_PACKET_SIZE | Maximal size of packet sent over network |
| ARMA3_TERRAIN_GRID | Terrain Grid |
