Unlocked FPS, wider FOV and other tweaks [Updated 2020]

Overview

Some useful tweaks I decided to share with the Steam community.

Preliminary

Start the game and configure your video options, so that some config files are generated.

Skip Intros

Right click Batman™: Arkham Knight in your Steam library and select Properties.

Left-click Set Launch Options

Write -nologo in the Steam launch options

Unlock FPS

Support for 60 and 90 fps was added after this guide was originally published.

1. Navigate to

   …your Steam folderSteamAppscommonBatman Arkham KnightBMGameConfig

2. open this file in your favorite text editor (i.e. Notepad)
   making a backup copy of it before editing is advisable

   BmSystemSettings.ini

   
3. search for this text string

   MaxFPS=XX.XXXXXX
   X = ingame fps setting (default = 30.000000)

   and change it to whatever value you wish the FPS to be capped

   e.g.
   MaxFPS=120.000000
   MaxFPS=144.000000
   MaxFPS=200.000000

   
4. save the file and exit the text editor

You might need to do this all over again in case you change some graphic options

Wider FOV

1. Navigate to

   …your Steam folderSteamAppscommonBatman Arkham KnightBMGameConfig

   

2. open this file in your favorite text editor (i.e. Notepad)
   making a backup copy of it before editing is advisable

   BmInput.ini

3. Locate this section

   [Engine.PlayerInput]

   copy all text strings starting with Bindings

4. Locate this section

   [BmGame.RPlayerInput]

   paste the text strings starting with Bindings at the end of this section

5. add the following lines at the bottom of what you’ve just pasted
   Bindings=(Name=”NumPadOne”,Command=”FOV 80″) Bindings=(Name=”NumPadTwo”,Command=”FOV 85″) Bindings=(Name=”NumPadThree”,Command=”FOV 90″) Bindings=(Name=”NumPadFour”,Command=”FOV 95″) Bindings=(Name=”NumPadFive”,Command=”FOV 100″) Bindings=(Name=”NumPadSix”,Command=”FOV 105″) Bindings=(Name=”NumPadSeven”,Command=”FOV 110″) Bindings=(Name=”NumPadEight”,Command=”FOV 115″) Bindings=(Name=”NumPadNine”,Command=”FOV 120″)
6. save the file and exit the text editor

Now you should be able to change the FOV ingame with your numpad keys. Make sure your Num Lock is ON.

FOV 100

FOV 110

FOV 120

You can manually modify the document further and personalize which key modifes FOV to which value.

Be aware that different FOV values alter aiming in first person perspective and other mechanics.

Additional Tweaks

You may want to hide the HUD to take screenshots like the ones above

1. open this file in your favorite text editor

   BmInput.ini

2. Add this line just after the portion of text you added to set the numpads as FOV keys

   Bindings=(Name=”NumPadZero”,Command=”ToggleHUD”)

Now the Numpad 0 key shows and hides the HUD.

1. open this file in your favorite text editor

   BmInput.ini

2. edit these lines to your liking

   MouseSensitivity=XX.X { i.e. 10.0 or 50.0 }

   bEnableMouseSmoothing=False to disable smoothing

Now available in video options

1. open this file in your favorite text editor

   BmSystemSettings.ini

2. edit these lines as follows

   MotionBlur=False
   MotionBlurPause=False
   MotionBlurSkinning=1

I noticed that ingame AntiAliasing no longer works after disabling Motion Blur, could be my issue.

Now available in video options

1. open this file in your favorite text editor

   BmSystemSettings.ini

2. edit this line as follows

   DepthOfField=False

Turning off DoF also disables gamma correction (negatively afftecting the whole scene lighting) and film grain.

Now available in video options

1. open this file in your favorite text editor

   BmSystemSettings.ini

2. edit this line as follows

   MaxAnisotropy=16

Not confirmed to work, you may need to force it through NVIDIA Inspector / ATI Catalyst.
