3DMigoto DX11 3D Vision Fix by mike_ar69 and bo3b
Acknowledgements
We are delighted to publish this game fix on the helixmod site, thank you to Helix and Eqzitara for supporting our work on the 3DMigoto DX11 Wrapper!
Fixed
1. Shadows
2. Lights
3. Double Imaging (fog and smoke)
4. Skybox elements
5. HUD
6. Water caustics
Disabled
1. Screen stuff like smudges and raindrops
2. Decals like blood etc (for now)
Game Settings
1. Shadows: Shadows must be "very high" or lower, 'soft shadows' have not been fixed (not even looked at yet). For performance reasons turning off soft shadows is a must anyway (the shader is 10000 lines long, compared to most of the others which are all < 600, this explains the processing hog)
2. Ambient Occlusion: SSAO has not been fixed (or looked at) yet. Use "Off", or HBAO+(low).
3. World Detail: Setting to low gives a good FPS boost, but removes gameplay elements, so really needs to be on medium/high
4. Motion Blur: Must be set to OFF
5. Antialiasing: if use in game settings then only Off, FXAA or SMAA work correctly, else there are lighting issues with night lamps. Recommend setting to "Off" and overriding in Nvidia Control Panel, or Nvidia Inspector (MSAA 2, 4 and 8 then all work).
Known Issues
0. Must change profile from AC4 to either no profile, or AC2 (or something else that works).
1. Rain splashes are 2d.
2. Sun Rays: appear 2D, but I can't seem to do anything about this.
3. Shadows from smoke are 2d (minor effect)
4. Text on in-game screens is too deep. This can be adjusted as part of varying the overall HUD depth using new settings in the d3dx.ini file:
[Constants]
x=0.8 <-- Change this one e.g. 0.4 is less depth, -0.2 will pop out the screen etc
y=0.8
z=1.2
w=2.0
5. Bloom from some Lights sometimes shines through objects. This might be an SLI issue, not sure
6. Reflections were fixed in the Animus place, but the fix is only approximate, and there is. some residual 'haloing'. This also affects puddles in Havana. Reflections in 3D are messed up bad actually, and we will continue working on it.
7. For some reason, when the game is started, you may need to change the depth setting a fraction (and then back to what ever it was) for the fix to kick in. Swithcing profile does not have this problem, but it's a minor annoyance, and has only recently been happening.
8. For Windows 8.1 64 Bit Update 1 you need to delete the dxgi.dll file that gets installed with the fix.
Installation
1. Make sure you have a platform patch installed.
This is an optional graphics patch from Microsoft. You need this update to avoid having 3Dmigoto crash.
You can look in your View Installed Updates, and search for KB2670838.
If you don't have it, you can get it here:
http://www.microsoft.com/en-us/download/details.aspx?id=36805
2. This fix requires that you either remove the AC4 profile using Nvidia Inspector, or set it to AC2, else the fix for reflections does not work. If you use the AC2 profile then you will be able to save settings, set SLI bits etc, but this might interfere with playing AC2...
3. Run the game once to make sure it's installed, resolution and refresh are like you want.
Make sure 3D kicks in.
4. If you are running recent drivers, and Compatibility Mode is kicking in, do Ctrl-Alt-F11 to disable it.
We've tested it on older drivers like 320.49 and the most recent Beta 337.50, and think it should work in all cases.
We've tested it with SLI and single GPU.
5. Get the fix as a zip file from here: https://github.com/bo3b/3Dmigoto/releases/download/0.63-beta/3Dmigoto-AC4-0.63_beta.zip
And unzip all of the files and ShaderFixes folder into the Assassin's Creed 4 exe folder.
e.g. "C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\games\Assassin's Creed IV Black Flag"
It's a lot of files, 400 or so shader files, and 16 dlls, an uninstall, and the .ini file.
If you need to uninstall, there is an uninstall.bat that will delete the dlls.
6) With all that installed, run AC4.
You should be able to see everything in 3D, and be able to change depth and convergence.
Performance should be good, very close to what you normally get with AC4 in 3D. You should see all of your CPU cores active.
First launch will be slow, like a minute, as it caches shaders.
