Field of view (FOV)[edit]

Changing FOV[4]
  1. Go to configuration file(s) location
  2. Open <user-id>.ArmAProfile in Notepad.
  3. Search for "fov". There are only 2 lines that contain fov near the bottom. They are:
    1. "fovTop" is vertical FOV, "fovLeft" is horizontal FOV
  4. Use this calculator to find your FOV values in degrees by entering your screen resolution.
  5. Convert these values from degrees to radians by entering "XX degrees in radians" in a Google search.
  6. Change fovTop to the value you have now, rounded to 2 decimal places.
  7. Divide your topFov number by the second number of your resolution's aspect ratio.
  8. Take the result of step 6 and multiply it by the first number of your resolution's aspect ratio.
  9. Change fovLeft to the value you have now, rounded to two decimal places.
  10. Save the file.

Some suggested FOV values in radians[5] for typical setups are:

Setup Type fovTop fovLeft
1920×1080 at 90 FOV 1.03 1.83
1680×1050 at 90 FOV 1.13 1.80
2560×1600 at 90 FOV 1.13 1.76
