Graphical tweaks[citation needed]

  • Set the 3D resolution and the interface resolution to exactly the same value. 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 the system, but due to the tweak above, it is safe to set the option to higher values.
  • For a higher frame rate and reduced input latency, turn off advanced 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. Nvidia Control Panel can also be used to increase.
  • For faster rendering, turn on PPAA instead of the normal anti-aliasing.
