Graphical tweaks[edit]

  • Set the 3D resolution and the interface resolution to exactly the same value. The value isn't as important, because no matter what, if the numbers don't equal, there will be performance loss. Ideally, both values would be set at 100.
  • Set Video Memory to "Default". By default (confusing, but keep reading), Arma II will cap the VRAM at an unspecified value. This value is actually lower than the "Default" option in the settings, but will still be named "Default".
  • Texture Quality is dependent on the amount of RAM in your system, but due to the tweak above, it is safe to set the option to higher values.
  • Disable VSync.
  • For a higher frame rate and reduced input latency, turn off the fancy options, like smoothing and head bobbing. To turn off motion blur, either download this mod or set post processing settings to "Very Low". This does speed up camera movement, so experiment to your liking. you can also use your Nvidia Control Panel as shown here to increase you frame rate.
  • For faster rendering, turn on PPAA instead of the normal AA (Anti-Aliasing).
