Field of view (FOV)[edit]

Adjusting FOV
  1. Go to %USERPROFILE%\Documents\Arma 3
  2. Open Username.Arma3Profile in Notepad.
  3. Search for "fov". fovTop is vertical FOV, fovLeft is horizontal FOV. There are only 2 lines that contain fov near the bottom: fovTop=XXXX; fovLeft=XXXX;
  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 multiplying your angle for π divided 180
  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 7 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 and close the file.

Some suggested FOV values in radians[3] 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

Notes

Range finding by using certain scopes like the PSO scope might not be accurate anymore when playing on a non-default FOV.

Issues fixed[edit]

Forcing game to use all RAM[edit]

Launch Options...
  1. Find Arma 3 in your Steam Library
  2. Right-click the game title
  3. Select Properties
  4. Select Set Launch Options...
  5. Input your launch commands based on what your system is, see below for more information
  6. Press OK
  7. Launch the game

For AMD CPU users:

  • AMD Dual-core with 4 GB RAM: -noSplash -cpuCount=2 -high
  • AMD Quad-core with 4 GB RAM: -noSplash -cpuCount=4 -high
  • AMD Six-core with 4 GB RAM: -noSplash -cpuCount=6 -high
  • AMD Eight-core with 4 GB RAM: -noSplash -cpuCount=8 -high

For Intel CPU users:

  • For Hyperthreaded CPU's such as a Quad Core: -cpuCount=8
    • This will enable your Hyperthreads on your CPU so your CPU will act as an eight core when running Arma 3.
  • If you are running a Hyperthreaded Six Core: -cpuCount=12
  • If you are running a Hyperthreaded Eight Core or Eight Core Xeon then apply this: -cpuCount=16
    • If you are running just a non-Hyperthreaded CPU such as a Quad Core then select "4" instead of "8" same for a Dual Core you will select "2" instead of "4".

Notes

All AMD CPU's are NOT Hyperthreaded so Hyperthreaded options is highly not recommended as this can cause system failure or damage.
The PCGamingWiki will not be responsible for system failure and damage if you choose to select more cores then you have on your command line!

Other commands:

  • -high: Makes your operating system prioritize services and processes to run your game better but this can cause system failure and instability if you dont have a good running system. If you Overclock this can cause system instability.
  • -cpuCount=[yourcpucount]: Enables extra CPU cores and Hyperthreads.
  • -maxMem=2047
    • Defines memory allocation limit to number (in MegaBytes).
256 is hard-coded minimum (anything lower falls backs to 256). 2047 is hard-coded maximum (anything higher falls back to 2047). Engine uses automatic values (512-1536 MB) w/o maxMem parameter yet FileCache was always excluded from the virtual address limit.
  • -maxVRAM=2047
    • Defines Video Memory allocation limit to number (in MegaBytes).
Use to resolve e.g. Windows problem: https://support.microsoft.com/kb/2026022/en-us?p=1 128 is hard-coded minimum (anything lower falls backs to 128). 2047 is soft-coded maximum, any value over 2GB might result into unforseen consequences!

Forcing correct monitor[edit]

  1. Edit Arma3.cfg in your config folder.
  2. Find forcedAdapterId parameter, set 0 for primary monitor, 1 for secondary, etc.
Specific parameter for linux users only :

You can also use --eon_force_display=x command line parameter on linux builds, where x is your monitor ID. Under steam, set command line like this : %command% --eon_force_display=0

Issues unresolved[edit]

Engine not utilizing CPU correctly[edit]

The Real Virtuality 4 has serious issues utilizing multi-core CPUs[5][6]
And due to the CPU not being utilizing correctly then nor will the GPU be utilized correctly

This issue is not new and everyone suffers. The developers have yet to comment on this issue on the official bug tracking site.

Failed to initialize BattlEye Service: Driver Load Error (577)[edit]

It is a known issue on Windows 10 Insider builds.[7]

Verify game cache

Seems to work for some users, others not.

  1. Find Arma 3 in your Steam Library.
  2. Right-click the game title.
  3. Select Properties, the Local files tab, then click on the Verify integrity of game cache button.
