- 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 models.
Alternate Planar Reflections
Alternate Planar Reflections can be enabled in-game. 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.

The biggest changes are shadow resolution and draw distance.

If you want Alternate Planar Reflections, you must select Alternate in the menu.

Then you're all set. I changed the values for Ultra instead of adding new names.

Everything is setting to on/ultra

So do you just copy paste file? Because I did this but I saw no difference in quality at all. It looks the same.. Am I doing something wrong?
