Alien: Isolation (DirectX11) - 3D Vision Fix
3DMigoto, DX11, 3D Vision fix by mike_ar69 and bo3b
Stereo Image 1
This game is a real showcase for how 3D can take a game to a whole new level, and makes it quite a bit more terrifying.
The game runs very well, SLI is supported and runs well with a good profile. In general, you can run the game in 3D with all settings at max. Be sure to use Deep Color to improve the black levels for color banding.

Installation
1.	The standard Alien Isolation profile on 344.65 and above works well.
2.	Run the game once to make sure it's installed, resolution and refresh are like you want.  Make sure 3D kicks in. It will look terrible.
3.	Get the fix as a zip file from here: 3Dmigoto-Alien-1.2.1.zip 
4.	Unzip the files and ShaderFixes folder into the game directory, for example:  C:\Program Files (x86)\Steam\SteamApps\common\Alien Isolation\
5.	Optional: Get the TAA Anti-Aliasing from: Alias Isolation
6.	Optional: Run the AliasIsolation GUI, and launch Alien Isolation from there.
7.	First run will ask for permissions, to set profile values, including TAA support.
8.	With that installed you should be able to run and see the fix. 
9.	Use in-game settings and set Particles to High, not Ultra if you use SLI and the particles seem bad (only draw in one eye). Fixed in later drivers.
10.	If you use single card, use in-game settings and set AO to Standard, not HDAO.
11.	For TAA (SLI is not supported), set in-game AA: SMAA T1x, Chromatic Aberration: Off, and Motion Blur: On.
Tweaks
1.	Lensflare and bloom are disabled by default.
Re-enable them if you prefer.  Edit the d3dx.ini and set the [Constants] field w=1.  By default this is zero, off.
2.	HUD+UI depth, including crosshair, are set to screen depth by default.
Set the depth if you prefer. Edit the d3dx.ini file, and set the [Constants] x=0.4 for depth, x=-0.2 for pop-out.
Note that this also affects some in-game items like terminals, which is why it's x=0 by default.
3.	Set crosshair independent of HUD if you prefer.
For example, use the [Constants] z=0.4 for depth.  By default this is set to zero because it also moves on screen info text.
4.	Convergence may be too high by default.  Use Ctrl-F5 to lower it.  Advanced settings must be enabled in Control Panel.
[Constants]
x = 0.0// HUD depth, 0.8=in screen, 0=screen depth, -0.2=popout
y = 0.05// reflection correction
z = 0.0// Crosshairs depth, 0.8=in screen, 0=screen depth, -0.2=popout, -1=none
w = 0// Set to 1 to enable lens flare and bloom
Known Issues
1.	Some lights will snap to different positions as you get close. 
2.	Planar reflections off floors is only approximate. Some may not yet be fixed. Can be disabled altogether in game's video settings.
3.	Some particle effects from fires show only in one eye if Ultra on SLI. Use High.
4.	On drivers above 344.11 HDAO will show double images if on single card. SLI is OK, as well as Standard AO.
5.	Aiming crosshair and dot are at screen depth, but can be moved deeper at the expense of some UI text glitches. Will move to 80% depth on right-mouse aim.
6.	Depth of Field will sometimes make the blurred part 2D. Relaunch game, maybe reboot.
7.	AA and AF are broken in game, not by us.  Use the TAA mod Alias Isolation, or downsampling, DSR, SuperSampling for AA instead.
8.	You may see ghosting because of hardware.  The game is super high contrast, and bright lights in dark rooms can expose hardware limitations.  Adjust your contrast and brightness and LightBoost to minimize it.
9.	For areas with a lot of water reflections, you will need to tune it to look good by adjusting convergence, or disable planar reflections.
Overall, we would rate this an excellent fix, the problems are barely noticeable.  If you see other effects that seem wrong, please let us know.
