By Kubas
Default ARMA 3 FOV is claustrophobic as it it's only 70°. However it can be changed and I highly recommend doing so.

1. Basic information
Default ARMA 3 FOV is claustrophobic as it provides 70° horizontal field of view. There is no option to edit it in game, but by changing config file it can be freely adjusted between 70° and 120°.

2. How to change FOV
  1. Go to C:\Users\[your_username]\Documents\Arma 3
  2. Open [your_username].Arma3Profile with text editor of your choice (I recommend notepad++)
  3. Find fovTop and set it to 1.03 (fovTop=1.03;)
  4. Find fovLeft and set it to 1.83 (fovLeft=1.83;)
  5. While we are here you may as well turn off smoothing and acceleration, find mouseSmoothing and mouseAcceleration, set both to 0 (mouseSmoothing=0; mouseAcceleration=0;)
  6. Save changes and close file
Two first values will increase FOV from claustrophobic 70° to nice 90°. You can set FOV how you prefer, just use any of these two for calculators so you will know how to set values:
I recommend using FOV between 85° and 100°

mouseSmoothing and mouseAcceleration will allow game to accept raw input from mouse instead of game trying to correct mouse movement. You can check what mouse smoothing is here[prosettings.net] and what mouse acceleration is here[prosettings.net]

it's so great that you have to choose between getting physically nauseous and being able to actually hit things with your gun when playing this game

I wish I knew this messed with scopes before i started sniping.

My first issue was following the normal formulas for mildot range finding with the M8451A SSDS (RHS scope) didn't work (I had to assume standing character height was 1.4 meters instead of 1.8 for it to rangefind properly).

Then I was trying to figure out why the 1 meter cube at 100 meters took up about 7.3 mildots instead of 10 mildots, then i thought that like a year ago i changed my FOV or something, and arma is weird so maybe that was the issue. And yep that was the issue. Guess i'm stuck with toilet paper roll FOV until they maybe one day add a patch letting you change FOV in game.
