ac odyssey care pakage

- description

All though odyssey is a beautifully lit game it does have a tendency,

as other games with similar lighting mass effect andromeda, dragon age

inquisition and origins, to go a bit overboard with

auto exposure - the transition from light to dark environments -

This mod tries to counterbalance this by reducing darkness and

over bright areas with a dynamic tonemap also reducing a slight

yellow tinge plus some luma sharpening sprinkled on top.

See screenshots plus settings game for examples.

The  package has a customized shader 'upscale.hlsl' which

does some fullscreen tweaks as sharpening and color modifications.

3dmigoto tweaks

- soften godrays

- remove water drops fx when diving into water

- a slight curve with custom shader curve.hlsl

update 14/10/2024 v1. 1

- tweaked tonemap a bitmore contrast

and saturation

- added shaders remove fx, reduce vignette and

reduce fog density (see shader list)

- install

Copy the contents of the zip file to the install folder of

assassins creed odyssey, the folder which contains ACOdyssey.exe.

- optional install

The following instructions are only needed

if you do not like using unverified dll's you can:

download 3dmigoto from

https://github.com/bo3b/3Dmigoto/releases

download version 1. 3. 16. 0 (64bits)) and place the following dlls in the

install dir of assassins creed odyssey:

d3dcompiler_46.dll

then copy ShaderCache, ShaderFixes plus d3dx.ini from the zip file to the same dir aka folder.

make sure to set (line 248):

the default setting is:

which sets 3dmigoto to a debug mode.

Also add at line 19:

include = ShaderFixes\upscale.ini

include = ShaderFixes\curve.ini

- verify

After running the game the folder ShaderFixes should

gradually (scene and level dependent) contain the .bin versions:

3f8c8e5bf6060d95-ps_replace.bin

767d3b2f46009ef1-ps_replace.bin

8b7c3744824a6cae-ps_replace.bin

a78acd74fdfee1fa-ps.bin

ad6b6e79d4880c69-ps.bin

upscale.hlsl

3f8c8e5bf6060d95-ps_replace.txt

767d3b2f46009ef1-ps_replace.txt

8b7c3744824a6cae-ps_replace.txt

a78acd74fdfee1fa-ps.txt

ad6b6e79d4880c69-ps.txt

upscale.hlsl

This means that the file(s) .txt have been compiled by 3dmigoto (d3d11.dll)

- tested

Tested with version 'gold edition' of assassins creed odyssey on

win 7 and win 10(1903) / nvidia 1050gtx ti

- performance

3dmigoto gpu usage 1080p@~45fps

without - clock 1746Mhz gpu usage ~95%

with       - clock 1746Mhz gpu usage ~97%

approximately 2% increase (1050gtx ti on win 7 / win 10(1903))

max gpu: 1772Mhz gpu usage 100%

**clamped frame rate to 45. 0 in game

- further tweaking

If you like you can compare the modified shader, ShaderCache contains

the original shader, to alter values.

The curve shader can be disabled by opening d3dx.ini

in a text editor and altering line 20 from:

include = ShaderFixes\curve.ini

;include = ShaderFixes\curve.ini

To disable specific tweaks remove, by example,

the following shader from the folder 'shaderfixes'

3F8C8E5BF6060D95-PS.txt

// soften godrays

and if compiled remove:

3F8C8E5BF6060D95-PS.bin

then restart the game.

Most shaders <shadernumber>ps_replace.txt have

a descriptive remark at top of the file (see shader list).
