Issues fixed[edit]

Vertical camera movement only with mouse[edit]

Fix Disconnect controller[5]

  1. Unplug your controller.
  2. Start a new game.

Crash during startup[edit]

Fix Disconnect any gamepads and then start the game[6]

Freeze/lag every now and then[edit]

Information A possible solution can be found at the official Amnesia A.M.F.P Troubleshooting Guide.[7]

Fix Edit main settings

  1. Go to %USERPROFILE%\Documents\Amnesia\Pig
  2. Open 'main_settings.cfg' in a text editor.
  3. Locate entry <Sound....
  4. Change MaxChannels="64" to MaxChannels="32".
  5. Change StreamBuffers="8" to StreamBuffers="4".
  6. Start the game and check if it worked.
  7. If not, also change StreamBufferSize="262144" to StreamBufferSize="131072".

Light halos showing through walls[edit]

Fix Start in offline mode[8]

  1. Start steam in offline mode or disable Steam Cloud for the game.
  2. Start the game and enter Launcher Settings.
  3. Select auto-detect video device.
Information Alternatively remove all .ini files from the game data locations for the game and try fix again.

Adjusting in-game gamma does nothing[edit]

Fix Disable gamma changing programs such as f.lux

Gamma changes persist after exiting the game[edit]

Information If the in-game gamma setting is increased, it can sometimes alter the desktop's gamma even after the game is closed.

Fix Use f.lux to restore gamma

  1. Download and install f.lux.
  2. Run it and the desktop gamma should return to normal.

Fix Enable Nvidia's own color settings in the Nvidia Control Panel[9]

Other information[edit]

Strong blue haze[edit]

Information The game has slight blue fog effect that is very apparent in the first level. This is intentional,[10] but this effect can be undesirably strong on some screens.

Fix Edit save files[11]

  1. Launch the game and create save if you don't have one.
  2. Go to %USERPROFILE%\Documents\Amnesia\Pig\<user-id>
  3. Locate your last save and open it in text editor.
  4. Locate entry name="mbFogActive" val="true" and change true to false.

Fix Edit shader files[12]

An alternative to the save game method is to edit the shader files. This has the advantage of being a permanent solution (instead of per-save), and it also allows you to reduce (or increase!) the effect by an arbitrary factor.

  1. Go to <path-to-game>/core/shaders
  2. Edit deferred_fog_frag.glsl.
  3. Locate entry float fAmount = max(fDepth / avFogStartAndLength.y,0.0); and change it to float fAmount = 0.0; to switch the effect off completely, or e.g. to float fAmount = max(0.25 * fDepth / avFogStartAndLength.y,0.0); to reduce the effect to 25 % of original.

System requirements[edit]

Information Integrated Intel HD Graphics should work but is not supported; problems are generally solved with a driver update.
