Baggy trousers every time I see one of those street
urchins shuffling by I think baggy trousers it's madness.
Assassins creed syndicate ubisoft 'wiedergutmachung' after
the dismal assassins creed unity.
It's a much better game technically but structurally
still has, lets say it's, issues.

The visual tweaks are listed below how ever a word of caution
if you have not played this game it might be wise to disable
the hud tweaks, at least initially, please see 'further tweaking'.

update 18/08/2023 v1.3
- a custom shader upscale.hlsl (3dmigoto) replaces reshade
- switched to internal AA
- added, less bright more orange lanterns
  illumination interior and exterior
- reworked down sampled cloud layer
  added more definition no longer removed
- modified fog tweaks effects mie / raleigh
  less dramatic (used to go dark)
- reworked day / night sky dome
- slight tweaks to tonemap shader

update 07/02/2022 v1.2
- a custom shader upscale.hlsl (3dmigoto) replaces reshade
- no longer use smaa by reshade switched to fxaa internal of game
- tested on windows 10 (v1903)
- reworked distance fog, mie / raleigh effect horizon is preserved more accurately
- tweaked frame based fx global lut, contrast and brightness

update 18/05/2020 corrections v1.1
Made a boo boo smaa was actually not active... ouch
- Corrected by activating smma.
- Switched to luma sharpening instead of adaptive sharpening
- tweaked the tonemap just a little reduces slight yellow tinge

3dmigoto shader tweaks:
- remove interior illumination, shadows plus tonemap daytime
- reduce overbright skin and hair illumination
- decrease fog exterior
- remove downsampeld cloud layer
- decrease specular exterior daytime

gameplay related shader tweaks:
- remove hud outline avatar when in stealth with crowd
- reduce hud outline friends and foes
- remove mono chromatic layer of eaglesense
- reduce hud pulse ground when in stealth with crowd

- updating

if the old package (1.1 or older) was installed remove the following
folder(s) and file(s) in the folder which contains acs.exe:

reshade
shadercache
shaderfixes

d3d11.dll
d3dcompiler_46.dll
d3dx.ini
dxgi.dll
dxgi.ini
ReShade.ini

Then copy the contents of the zip file to the install folder of
assassins creed syndicate, the folder which contains acs.exe.

- install

The package works best with following settings:
Bloom=0
PostFX=0

Settings can be found in:
c:\Users\<username>\Documents\Assassin's Creed Syndicate\AC.ini

Copy the contents of the zip file to the install folder of
assassins creed syndicate, the folder which contains
acs.exe.

The folder 'optional' contains a 'AC.ini' you can use this to
compare it with the 'AC.ini' on your system to make the necessary changes.
See: c:\Users\<username>\Documents\Assassin's Creed Syndicate\AC.ini

- 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 and place the following dlls in the install dir of
assassins creed syndicate:
d3d11.dll (64bits)
d3dcompiler_46.dll
d3dx.ini
then copy ShaderCache and ShaderFixes from the zip file to the same dir aka folder.

note: if you choose to use the d3dx.ini contained in the github package
make sure to set (line 248):
hunting=0
the default setting is:
hunting=1
which sets 3dmigoto to a debug mode.

Also change line 19 from:
;include = ShaderFixes\upscale.ini
to:
include = ShaderFixes\upscale.ini

- verify

After running the game the folder ShaderFixes should
gradually (scene and level dependent) contain the .bin versions:

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

- tested

Tested with file version 1.51 of Assassins creed syndicate
on win 7 / nvidia 1050gtx ti
See screenshot for settings game.

- performance

reshade / 3dmigoto gpu usage 1080p@~45fps
without - clock 1594Mhz gpu usage ~95%
with       - clock 1760Mhz gpu usage ~96%
approximately 4% increase (1050gtx ti on win 7 / win 1091903))
max gpu: 1772Mhz gpu usage 100%
**clamped frame rate to 45.0 no sync

- further tweaking

If you like you can compare the modified shader, ShaderCache contains
the original shader, to alter values.

To disable the game play related tweaks please remove
the following shaders from the folder 'shaderfixes'

3a1026176bc3b7a0-ps_replace.txt
613a41d94e13d51d-ps_replace.txt
c4eebf5964f64f4c-ps_replace.txt
e525bbb219b65ffb-ps_replace.txt

and if compiled remove:

3a1026176bc3b7a0-ps_replace.bin
613a41d94e13d51d-ps_replace.bin
c4eebf5964f64f4c-ps_replace.bin
e525bbb219b65ffb-ps_replace.bin

then restart the game.
