All though witcher 3 is a beautifully lit game it does have a tendency,
to saturate the colors quite a lot plus add quite some contrast which
can result in very 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 quite a lot of desaturation and some texture
relief is added.
See screenshots plus settings game for examples.

The mod modExtendedViewDistance thins fogs in the distance this
plays a pretty specific role in the look and feel of environments
I would recommend having a look at it:

update 15/02/2022 v1.1
- a custom shader upscale.hlsl (3dmigoto) replaces reshade
- tested on windows 10 (v1903)
- reworked auto exposure day and night environment added fake light

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

- updating

if the old package was installed remove the following
folder(s) and file(s) in the folder which contains witcher3.exe

reshade

dxgi.dll
dxgi.ini
ReShade.ini

Then copy the contents of the zip file to the install folder of
the witcher 3, the folder which contains witcher3.exe.

- install

Copy the contents of the zip file to the install folder of
the witcher 3 wild hunt\bin\x64, the folder which contains witcher3.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 and place the following dlls in the install dir of
euro truck simulator 2:
d3d11.dll (64bits)
d3dcompiler_46.dll
then copy `d3dx.ini, 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.

- verify

After running the game the folder ShaderFixes should contain the .bin versions:

upscale.ps.bin
upscale.vs.bin

of

upscale.hlsl
upscale.ini

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

- tested

Tested with version 1.21 of the witcher 3 on
win 7 and win 10 / nvidia 1050gtx ti

- performance

3dmigoto gpu usage 1080p@~50.2fps
without - clock 1290Mhz gpu usage ~95%
with    - clock 1342Mhz gpu usage ~96%
approximately 3% increase (1050gtx ti on win 7 / win 10)
max gpu: 1772Mhz gpu usage 100%
**clamped frame rate to 50.2 no sync

- further tweaking

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

To disable specific tweaks open the shader from
the folder 'shaderfixes' with a text editor.

All shaders <shadernumber>ps_replace.txt have
a descriptive remark at top line. (see shader list)
