 Startup Parameters
Startup parameters for the ArmA series are quite complicated, due to the engine being so complicated. An extensive accounting of the available parameters can be found here.

 Graphic Tweaks
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.
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.
For faster rendering, turn on PPAA instead of the normal AA (Anti-Aliasing).
To trick the engine into using all the power that your system has, add these commands to your startup parameters:
-maxmem=[yourmemory] -maxvram=[yourvidcardmemory] -cpuCount=[availableCPUcores] -exThreads=[number] (The number varies. 1 if you have a two cores, 7 if you have a four or more. Feel free to experiment with this setting to see if anything grants you higher performance.)
 Disabling the Intro
Add these commands to the startup parameters:
 Game data
|Windows||%USERPROFILE%\My Documents\ArmA 2|
 Video settings
|Field of view (FOV)||See Field of view (FOV)|
|Borderless fullscreen windowed|
|Anisotropic filtering (AF)|
|Anti-aliasing (AA)||The game has a selection of pre and post process AA|
|Vertical sync (Vsync)|
The Field of View can be changed in Arma 2 and mods such as Day Z by following the steps below.
- Go to
%USERPROFILE%\My Documents\ArmA 2
- Search for "fov". There are only 2 lines that contain fov near the bottom. They are:
fovLeft=XXXX;fovTop is vertical FOV
fovLeft is horizontal FOV
- Use this calculator to find your FOV values in degrees by entering your screen resolution.
- Convert these values from degrees to radians by entering "XX degrees in radians" in a Google search.
- Change fovTop to the value you have now, rounded to 2 decimal places.
- Divide your topFov number by the second number of your resolution's aspect ratio.
- Take the result of step 6 and multiply it by the first number of your resolution's aspect ratio.
- Change fovLeft to the value you have now, rounded to two decimal places.
- Save the file.
Some suggested FOV values in radians for typical setups are:
|1920 x 1080 at 90 FOV||1.03||1.83|
|1680 x 1050 at 90 FOV||1.13||1.80|
|2560×1600 at 90 FOV||1.13||1.76|
NOTE: Range finding by using certain scopes like the PSO scope might not be accurate anymore when playing on a non-default FOV.
