Revision as of 22:58, 26 November 2020

Template:SideTOC Template:wip Arma 3 performance has always been a great interrogation topic. This page brings light on some aspects of the video settings.


General Guidelines

  • use auto-detection as a base for other settings - the autodetect button know best, most of the time
    • an exception to that being that auto-detection will set the render samping to at least 100% - this is not ideal if one wants to play e.g in 1K on a 4K screen.
  • in order to bring some relief to the CPU, play with (terrain/object) view distance
  • to alleviate pressure on the GPU, lower PiP settings and reduce 3D Sampling (e.g 50% on a 4K screen = 1920×1080)
⚠
  • Do your tests on a Vanilla (no mods) Arma 3! Some ill-conceived mods can bring performance down.
  • Do your tests in a single player environment. If your performances in multiplayer are worse than in single player, the server/connection/mission is at fault; there is nothing you can do.
