Performance Metrics: Server FPS

In Arma 3, “Server FPS” is not a measure of graphical smoothness, but rather a metric of simulation cycles per second. It dictates how frequently the server calculates AI pathfinding, projectile trajectories, and network synchronization. A low Server FPS results in “desync,” causing vehicles to teleport, bullets to fail to register, and AI units to become unresponsive.

Interpreting Server Health

Use the table below to determine if your mission is running optimally or if the server is overloaded.
  • Excessive AI Counts: Having 500+ AI units active simultaneously will overwhelm even the fastest CPUs.
  • Script Loops: Check your server .RPT logs for recurring error messages. Infinite loops or heavy scripts running onEachFrame are common culprits.
  • Garbage Collection: Ensure your mission has a cleanup script to delete dead bodies, dropped weapons, and wrecked vehicles.
