- updating from the previous care package if installed

remove the following files found under game dir:
effects\config.xml
postprocess\effects.xml

and restore with:
dirt 3 original files\effects\config.xml
dirt 3 original files\postprocess\effects.xml
contained in package or if you have made a backup with
your backup copy of the files.

- install

Copy the contents of the zip file to the install folder of dirt 3,
the folder which contains dirt3_game.exe

- optional install

download 3dmigoto from:
https://github.com/bo3b/3Dmigoto/releases
download version 1.3.16 and place the following dlls in the install dir of
dirt 3:
d3d11.dll (32bits)
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

The 3dmigoto can be verified by:
After running the game the folder ShaderFixes should contain the .bin versions:

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

- tested

Tested with the complete edition of dirt 3 on win 10 (1903) / nvidia 1050gtx ti

- performance

gpu usage (game capped at 60.7 frames) plus fast sync
with - clock 987Mhz gpu usage ~70%
without   - clock 987Mhz gpu usage ~70%
no measurable difference with 1050gtx ti on win 10 (1903)
max gpu: 1784Mhz gpu usage 100%

- 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 open the shader from
the folder 'shaderfixes' with a text editor example:
9C5F6336A0D8E4BF-PS_REPLACE.TXT

Has a remark on the top line:
// reduce brightness upper part cockpit

So if you do not want that to happen
remove the shader from the folder 'shaderfixes'

9C5F6336A0D8E4BF-PS_REPLACE.TXT

and if compiled remove:

9C5F6336A0D8E4BF-PS_REPLACE.BIN

then restart the game.

All shaders ps_replace.txt have a similar descriptive remark.
