All though origins is a beautifully lit game it does have a tendency,
as other games with similar lighting mass effect andromeda, dragon age
inquisition and origins follow up odyssey 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.

Note(s):
The  package has a customized shader 'upscale.hlsl' which
does some fullscreen tweaks as sharpening and color modification.

update 06/12/2023 v1.1
- added 3dmigoto shadertweaks
- a custom shader upscale.hlsl (3dmigoto) replaces reshade
- added a slight curve with custom shader curve.hlsl

3dmigoto tweaks

- reduce mist and dust banks
- remove water drops fx sailing boat, etc
- reduce fog density

- updating

if the old package was installed remove the following
folder(s) and file(s) in the folder which contains ACOrigins.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 origins the folder which contains ACOrigins.exe.

- install

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

The following instructions are only needed

- 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 origins:
d3d11.dll
d3dcompiler_46.dll
then copy ShaderCache, ShaderFixes plus d3dx.ini 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 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:

4d044382b47c9309-ps.bin
51144a00b5033bd7-ps_replace.bin
b4fd40226007405b-ps.bin
curve.hlsl
upscale.hlsl

4d044382b47c9309-ps.txt
51144a00b5033bd7-ps_replace.txt
b4fd40226007405b-ps.txt
curve.hlsl
upscale.hlsl

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

- tested

Tested with version 1.5.1 of assassins creed origins on
win 7 and win 10(1903) / nvidia 1050gtx ti

- performance

3dmigoto gpu usage 1080p@~45fps
without  - clock 1584Mhz gpu usage ~95%
with       - clock 1720Mhz gpu usage ~96%
approximately 2% increase (1050gtx ti on win 7 / win 10(1903))
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.

The curve shader can be disabled by opening d3dx.ini
in a text editor and altering line 20 from:
include = ShaderFixes\curve.ini
to:
;include = ShaderFixes\curve.ini

To disable specific tweaks remove, by example,
the following shader from the folder 'shaderfixes'

51144A00B5033BD7-PS_REPLACE.txt
// reduce fog density

and if compiled remove:

51144A00B5033BD7-PS_REPLACE.bin

then restart the game.

Most shaders <shadernumber>ps_replace.txt have
a descriptive remark at top of the file (see shader list).
