I didn't write this, just copied from another place.

Go to My Documents> My Games> Outlast> OLGame> Config

All files are there.

You probably have to check the box "Read only" in the most of files.

First of all make sure you make a backup of all the files (just copy all of them into another folder or make a RAR file in the same folder, it works for me).

Also, you don't have to change all written below, just change whatever you want.
In my case, only changed the FOV and Texture resolutions.

How to Change FOV

Go to "OLGame.ini", open it, look for "DefaultFOV=" and "RunningFOV=", defaultfov is by default at 90 but is not the 90 that all we now, it is like 65, so to get like 90 you have to write:

DefaultFOV=110.0
RunningFOV=120.0

This is like FOV 90 in other games (like Battlefield, etc)

IMPORTANT: When you look through your camera you have the old defalut FOV, so to change the default Camera FOV, change this parameters:

CHANGE CAMCORDER/ CAMERA FOV

CamcorderNVMaxFOV=83.0
CamcorderMaxFOV=83.0

TO this:

CamcorderNVMaxFOV=110.0
CamcorderMaxFOV=110.0

Use whatever works for you.

How to Change FPS limit (Uncap FPS)

So, to uncap fps open "OLEngine.ini" and look for:
bSmoothFrameRate=TRUE
MinSmoothedFrameRate=22
MaxSmoothedFrameRate=62

So change it to:

bSmoothFrameRate=FALSE
MinSmoothedFrameRate=0
MaxSmoothedFrameRate=0

(0 means UNLIMITED)

Better Texture Resolution

In "OLEngine.ini" change this:

MaxProcBuildingLODColorTextureSize=1024
MaxProcBuildingLODLightingTextureSize=256

To this:

MaxProcBuildingLODColorTextureSize=2048
MaxProcBuildingLODLightingTextureSize=1024

Remove Motion Blur

Open "OLSystemSettings.ini", change this:

MotionBlur=True
MotionBlurPause=True
MotionBlurSkinning=1

to this:

MotionBlur=False
MotionBlurPause=False
MotionBlurSkinning=0

Antialiasing (MSAA) [Working fine on my AMD GPU]

In "OLSystemSettings.ini", change this:

MaxMultiSamples=1
bAllowD3D9MSAA=False

to this:8

MaxMultiSamples=2
bAllowD3D9MSAA=True

(In "MaxMultiSamples=" you can use 2, 4, or 8 I think)

[nVidia Users Only] Antialiasing (SGSSAA) (CalinTM)

Originally posted by CalinTM:

To use SGSSAA, you need a nvidia GPU and follow these steps from here:

This does require a powerful system!

• Download Nvidia Inspector
• Open up the program
• Open up the Profile settings ( Tool button on the right side of driver version )
• Open the Outlast profile ( if you havn't created it yet, look in the previous section )
• Paste 0x000010C1 in the "Antialiasing Combatibility" section
• Set "Antialiasing - Mode" to: Override any application setting
• Set "Antialiasing - Setting" to: 2x [2x Multisampling]
• Set "Antialiasing - Transparency Supersampling" to: 2x Sparse Grid Supersampling
• Set "Lod Bias" to: -0.500 for 2x
• -1.000 for 4x
• -1.500 for 8x

Note: you can set it to 4x or even 8x if your system is powerful enough, always be sure that the values in multisampling and supersampling match up.

Also if you want to enable Physx on the GPU instead of CPU, modify this to False
bDisablePhysXHardwareSupport=False (found in OLEngine.ini)"

Change Resolution

In the same file, look for:
ResX=
ResY=

Change it to whatever you want (800x600, 1920x1080, etc)

For Example:

ResX=1920
ResY=1080

(If you are getting black screen you can try "fullscreen=true" to "fullscreen=false", (I don't even know if it works, but maybe...) and change screen resolution to a lower one, and check your drivers, and install/update directX...)

Change Battery Life

Originally posted by Note:
Try to use only if you are stuck somewhere or ran out of batteries.

Go to "OlGame.ini" and change this: BatteryDuration=150.0
to the desired value. I think it is measured in seconds, so 150 seconds.

For Example: BatteryDuration=300.0
for 300 seconds of battery life (I THINK)

Modify Grain Filter

Go to: C:Program Files (x86)SteamSteamAppscommonOutlastEngineConfig

Then open "ConsoleVariables.ini" and underneath "[Startups]" write: "ImageGrain = 0.0" or the desired value.

So it looks like:

[Startup]
ImageGrain = 0.0

That's all, have a nice hunting in Outlast, despite who is the hunter and who is the hunted.
