Setting Up The Mod

How to Properly Set Up Dead's Overthrow

While it is entirely possible to play the mod locally in Arma 3, there is a large flaw that may heavily detract from the play experience:

Arma3's spawning, ai calculations, and garbage collection algorithms run thousands of times slower on a client than on a server instance, because these are used constantly in Overthrow (due to poor programming decisions), the performance while running the scenario on the client will most likely be less than desirable. Running it on server, on the exact same computer, will always give SIGNIFICANTLY better performance.

Running the mod on a server, and connecting to it as a client, even in singleplayer, is almost essential to get a playable framerate.

Luckily, setting up this mission, or any mission in fact, is not that hard to do. To emphasis the point, running the mod locally on my high-end gaming PC will frequently drop to ~20fps just by driving around, and even enter the single digits in the major towns. However, when playing the mod with a friend who was hosting the server on his low-mid range gaming PC (and playing on the same computer) neither of us reported any noticeable frame rate drops during our 8+ hours of play!

By using a server management tool, my personal recommendation is FASTER, the process is almost painless, and can be done without needing the Steam Terminal, or an extra directory, incase disk space is limited.
