How to increase FOV in ARMA

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°.

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:

• Metalman's calculator[hia3.com]
  
• OLoKo64's calculator[gamecalculator.netlify.app]

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]
