Ultra-widescreen

Enable Ultra-Widescreen[4]
  1. Use Widescreen Fixer
  2. Untick Automatically Detect Resolution.
  3. In Display Count Enter 3.
  4. Enter your desired resolution into Detected Resolution.

Field of view (FOV)

Add FOV hotkey[5]
  1. Go to <path-to-game>\APGame\Config\
  2. Open DefaultInput.ini.
  3. Go to ; --- General bindings
  4. Add the line +Bindings=(Name="F11",Command="Fov 93")
  5. Press F11 during gameplay to activate your chosen FOV.

Notes

High FoV causes several issues
  • Most of cutscenes show models before they should appear in view, making them appear out of nowhere or get stuck
  • Sniper scope no longer zooms
  • Player model in Service Record is small

Anisotropic filtering (AF)

Modify APEngine.ini[citation needed]
  1. Open %USERPROFILE%\Documents\Alpha Protocol\APGame\Config\APEngine.ini
  2. Change MaxAnisotropy to one of the following values: 0, 2, 4, 6, 8, 12, 16.

Anti-aliasing (AA)

MSAA[citation needed]
  1. Open Alpha Protocol driver profile via Nvidia Profile Inspector.
  2. Change Antialiasing compatibility to 0x00000041[6]
  3. Change Antialiasing - Mode to Override any application setting
  4. Change Antialiasing - Setting to 4x [4x Multisampling] or one of the other MSAA options.
  5. Apply changes.

Notes

Default Nvidia profile has wrong anti-aliasing compatibility bits for Alpha Protocol. Therefore, when MSAA forced through video driver in-game dialogue choices show missing.
SGSSAA[citation needed]
  1. Open Alpha Protocol driver profile via Nvidia Profile Inspector.
  2. Change Antialiasing compatibility to 0x080002C1[7]
  3. Change Antialiasing - Mode to Override any application setting
  4. Change Antialiasing - Setting to 4x [4x Multisampling]
  5. Change Antialiasing - Transparency Supersampling to 4x Sparse Grid Supersampling
  6. Apply changes. SGSSAA can be set higher(8x) but it must always match the MSAA value.

High frame rate

Modify APEngine.ini[citation needed]
  1. Go to the configuration files location.
  2. Open APEngine.ini.
  3. Change bSmoothFrameRate=TRUE to bSmoothFrameRate=FALSE
May cause stuttering.

Issues fixed

Can't activate (Error code: -1912029)

Install Patch 1.1[10]

Install Patch 1.1 to remove the activation requirement.

Game won't get past the launcher

Reinstall Nvidia PhysX[citation needed]
  1. Uninstall Nvidia PhysX.
  2. Install the Nvidia PhysX System Software.

Hitching / Stuttering

Modify APEngine.ini[citation needed]
  • Edit %USERPROFILE%\Documents\Alpha Protocol\APGame\Config\APEngine.ini
  • Set these lines to the following values:
bSmoothFrameRate=True
bUseBackgroundLevelStreaming=False
UseTextureFileCache=True
OnlyStreamInTextures=True
OneFrameThreadLag=False
UseVsync=True
  • Set this line to match your monitor's refresh rate:
MaxSmoothedFrameRate=62
  • Save the file
  • On nVidia GPU's setting Vsync to "Fast" can help as well. Disable in game Vsync when doing this.
Jerky camera movement[citation needed]

Setting the graphics tweaks as previously mentioned will disable background streaming and make the jerky camera occur less often. Using and enabling a controller will all but eliminate it.

No text visible for dialog choices

No Text Visible for Dialog Choices[citation needed]

When MSAA anti-aliasing enabled via video driver with default anti-aliasing compatibility bits this issue seems to occur. See Anti-aliasing (AA) for the solution.

Motion Blur option doesn't work

Modify APEngine.ini[citation needed]
  1. Go to the configuration files location.
  2. Open APEngine.ini.
  3. Adjust GlobalMotionBlurAmount=

Graphical tweaks

The graphics settings for Alpha Protocol are rather basic. There are some other settings which can be altered in the APEngine.ini file, found in the configuration files location.
Before editing the file, the read-only tag needs to be removed.

Editing the following settings should improve the game's graphics:

  • Trilinear=True
  • EnableHighPolyChars=True
  • MaxShadowResolution=4096 (If you experience framerate issues, this can be lowered to 2048 or 1024)
  • bEnableBranchingPCFShadows=True
  • bEnableForegroundShadowsOnWorld=True
  • bUseBackgroundLevelStreaming=False
  • OnlyStreamInTextures=True
  • OneFrameThreadLag=False

Audio tweaks

The sound settings for Alpha Protocol are very rudimentary. There are some other sound settings which can be altered in the APEngine.ini file, found in the configuration files location
Because the game has OpenAL support, the sound quality can be improved with a couple of changes within the ini file, especially when a hardware-based audio solution (e.g. Creative SoundBlaster) is used.
Before editing the file, the read-only tag needs to be removed.
  • [ALAudio.ALAudioDevice]
  • MaxChannels=32 (some hardware-based soundchips support up to 256 channels. Common settings are 48,64,96,128)
  • UseEffectsProcessing=True
  • TimeBetweenHWUpdates=15
  • MinOggVorbisDurationGame=20
  • MinOggVorbisDurationEditor=4
  • DeviceName=Generic Hardware (changed from DeviceName=Generic Software; nearly all gaming soundcards support OpenAL via hardware-based emulation)

Surround Sound and EAX support

This game seems to work with the ALchemy software for supported Creative SoundBlaster soundcards.
Doing so may break dialogue UI[citation needed]
Edit APEngine.ini[citation needed]
  1. Edit the APEngine.ini file and change the line: DeviceName=Generic Software to DeviceName=Generic Hardware
  2. Add the game to the list within Creative ALchemy by pointing to <path-to-game>\Binaries

Notes

  1. 1.0 1.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/34010/ in addition to or instead of this directory. The app ID (34010) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
