I’m planning to run many instances of headless Godot to simulate loads of traffic in my MMO game. How’s the memory usage of a headless Godot instance? I’m curious whether it really have to load the textures and meshes since those won’t be visible anyways.
You can test it yourself by running your game with the --headless parameter from a terminal/cmd. It will use a dummy audio and render servers so no audio or visuals will be processed.
You can specify what to do with your assets when exporting the game to run in a dedicated server. More info here Exporting for dedicated servers — Godot Engine (stable) documentation in English
