Three years after the conflict in Chernarus, portrayed in the original Arma 2, a new flashpoint explodes in the Green Sea Region. Coalition forces led by the US Army are deployed to Takistan to quickly restore peace and prevent further civilian casualties. You will enlist into various roles within the US Army, from basic infantrymen, through special operatives, to pilots and tank crew in this new installment in the award winning line up of military simulators for PC from Bohemia Interactive. Building on 10 years of experience and constant engine development, Arma 2: Operation Arrowhead boasts the most realistic combat environment in the world. It models real world ballistics & round deflection, thermal imaging, materials penetration, features a realtime day/night cycle and dynamic wind, weather and environmental effects.
ENB and SweetFX for ARMA 2 Operation Arrowhead & Expansions. This is a Place and Play, no adjustments required.

Win10 users make the following adjustment as shown in the video below.
Use the following launch option when starting game.
Nvidia Users. Enable DSR in your Nvidia control panel (as shown here), under the global settings. (I checked all the boxes to allow for all the resolutions).
ATI Users: Enable VSR here.
If game appears dark.
Make this alteration to Arma2OA.txt in the sweetFX\Preset folder. Change the define USE_SMAA_ANTIALIASING to 0.
If game has performance issues or microstutters.
Open enbseries.ini in the game folder and change the line under [GLOBAL] AllowAntialias=1 to AllowAntialias=0.
This is a combination of several different setting files and programs I found I could use with one another (after some adjustments) for Arma 2 Operation Arrowhead and the expansions. It adds detail, shading and lighting, while enhancing colors but not altering the base colors of the game.
This can be used in combination with any texture packs or add-ons.
To make adjustments to ENB, alter the enbseries.ini configuration settings file, found in the main folder.
To make adjustments to Sweetfx, go to \SweetFX\Presets and alter the Arma2OA.txt file.
The default settings file is located in the main folder, SweetFX_settings.txt. However, it is not used for the settings as the SweetFX_preset.txt file is directing it to the presets folder (alter to match, if you make change to location or name of settings file).
Using the Printscreen, will generate ingame screenshots.
They can be found placed in the game folder, where the files were placed.
Use FastStone Image Viewer, to convert them to jpg or other formats.
Alter ENB and SweetFX settings as you like.
