- 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

- Find and change the following settings to the values shown below:
InteractDistance=250
CoverWalkSpeed=75.f
CoverRunSpeed=125.f
PlayerRotationSpeed=80000.0f

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 you must right click it, select properties, and uncheck the "read only" box. Editing the following settings should improve the game's graphics. It is highly recommended to make a backup of this file before editing it.
Trilinear=True
EnableHighPolyChars=True
MaxShadowResolution=4096
(If you experience framerate issues, this can be lowered to 2048 or 1024)
bEnableBranchingPCFShadows=True
bEnableForegroundShadowsOnWorld=True
UseBackgroundLevelStreaming=False
OnlyStreamInTextures=True
OneFrameThreadLag=False
Afterwards, check the "read only" box in the file's properties.
