Simply drag and drop to replace the file ENGINE_SETTINGS.XML.

Default location of ENGINE_SETTINGS.XML:

The drive and Steam Library where you have the game installed...
SteamApps\common\Alien Isolation\DATA
- LOD value of 6.0 is Ultra. Previous 1.0 value is High.
- 3072 and 4096 values added to Shadow Resolution as Very High and Ultra.
- Alternate Planar Reflections added that ignore the values found in the reflection map. Not enabled by default. To enable, change from On setting to Alternate.
- Streaming Texture Heap Size raised to 1024 for better texture resolution and streaming performance
- Streaming Model Heap Size raised to 512 for better model resolution and streaming performance
- Field of View values changed to horizontal FOV
Level of Detail (LOD)
Alien: Isolation uses Level of Detail (LOD) to reduce detail once objects are a certain distance from view, and while this method works well it does cause objects to pop in and out of detail.

Below are two images, one taken with the previous Ultra value and one taken with the new Ultra value.

LOD (1.0) Ultra
LOD (6.0) Ultra
Shadow Map Resolution
Shadow Map Resolution is limited to 2048 in Alien: Isolation by default. 4096 shadow map resolution can be accessed in-game with the modded file for better shadows with the Ultra preset.

2K (2048) Standard Shadows
4K (4096) Standard Shadows
Horizontal Field of View (FOV)
Alien: Isolation uses Vertical FOV instead of Horizontal FOV. The values have been renamed to avoid confusion and converted to horizontal values in-game.

85 is the recommended value, and any value higher than 85 will result in no legs for Ripley and other first person player models.
Alternate Planar Reflections
Alternate Planar Reflections can be enabled in-game by toggling the setting to Alternate. This setting will ignore the reflection values found in the map files.

Anisotropic Filtering
Force 16X Anisotropic Filtering in your videocard's control panel for high quality AF.
Recommended Mods
Here you'll find a list of mods I highly recommend that will enhance your gameplay experience in Alien: Isolation.

* Alias Isolation[]
A fantastic mod that adds TAA (Temporal Anti-aliasing) which eliminates all aliasing in the game. Highly recommended. There may be visual anomalies when depth of field effects are used. The mod is constantly being updated, so it it likely that the issues will be eliminated in the future.
* Unpredictable Alien
A great mod that makes the alien more unpredictable by giving it more freedom to roam the ship instead of constantly stalking you. The mod affects all difficulty levels and modifies the alien's leash to the player and time spent in vents.

I have a question: Since i'm forcing AF with Nvidia, can I turn off the ingame AF?

This is amazing! Using this mod, Alias Isolation, 4K DSR and a Sweet FX (Dark and bleak), the game truly looks incredible!

I'm so happy the devs gave the option of turning off all the cinematic bs (Filmgrain, dof, chromatic, etc) as well!

Years of playing with config files. Found files and changed values.

Just curious, how did you come up with the mod? What set of skills do you have that I lack of?
FutureCop Oct 23, 2017 @ 10:57am 
@Angel okay Angel thank you very much for your response.
I will give it a try.

Just replace the file. I've left the naming in-game the same, so you'll still see "Ultra" if you selected it, but it will be using different values, which the game engine will process and provide you with better visuals. You'll no longer get pop-in when walking around and the textures will load at full resolution.

I recommend you set the FOV to 85, as anything higher will remove legs when you look down, unless you don't care about that and want a wider field of view.

As for the TAA mod, you have to follow the directions that it provides to run it properly. Basically, you have to start Alien Isolation through the TAA mod's launcher once per Steam session to activate the mod. If you close Steam or restart your PC, then you will have to run the game through the mod's launcher again to get TAA working.

Well... I'm still confused. Okay , I need to install the modded settings file in SteamApps\common\Alien Isolation\DATA ? And do i need to remove the original ENGINE_SETTINGS file first?
