Performance Optimisation – Arma 3

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)

Quality	Sampling	Template:colorball	Template:colorball	Defines the game's 3D resolution based on Display's Resolution setting (in %) - e.g 50% of 3840×2160 (4K) results in a 3D resolution of 1920×1080 (1K, 1/4 of the original resolution)
