Arma 3 (32 or 64-bit)

From their Site

Experience true combat gameplay in a massive military sandbox. Deploying a wide variety of single- and multiplayer content, over 20 vehicles and 40 weapons, and limitless opportunities for content creation, this is the PCs premier military game. Authentic, diverse, open - Arma 3 sends you to war.

Installation Requirements

  • A valid, real Steam account, with Steam Guard turned off, is required to install the server (default "anonymous" login cannot be used). For security reasons it is recommended that you create a new Steam account just for your dedicated servers. This account does not need to own Arma 3.
  • For automatic Steam Workshop mod downloading to work, the Steam account does need to own Arma 3. This is, of course, optional functionality, and mods can be manually uploaded to the server if desired.

Minimum RAM Warning

This server requires about 2048 MB to run properly.

CPU Usage Information

ARMA 3 is mainly CPU intensive. Contrary to popular belief, the server binary can run on multiple cores/threads. However, it's ability to manage asynchronous tasks and hyperthread is very limited, meaning additional cores/threads reach diminishing returns very quickly. In addition, it's ability to utilize all of the CPU alloted to it for AI processing seems to be limited as well. Therefore, a headless client and a properly written mission file are highly recommended if large amounts of AI units will be used. An Arma 3 Headless Client Egg can be found here.

Additional Settings

Additional server flags can be found here.
These can help you fine tune how the server will behave during runtime.

Note: The -maxMem= flag is currently known to cause an unknown segmentaion fault crash on startup. Other hardware related flags may cause similar behavior.

Server Ports

Default server ports. It is recommended that each server be 100 ports seperate from each other.
