Dirt 3 just one word - gymkhana - love it or hate it this is pretty
much dirt 3's defining aspect. Nice idea but really challenges your
skills once you switch to cockpit view, no joke.

update 14/10/2024 v2.3
- tweaked tonemap a bit more contrast
  and saturation
- fixed 'remove artificial sun globe on tracks'
  caused greyed out mountains with rainy and
  cloudy weather conditions
- tweaked 'reduce flare reflections chrome, etc'
  pretty much removes flare now
- added 'remove lensflare B' shader

update 08/03/2024 v2.2
- added remove filter tint to splitscreen mode
  kudos to 'Tronie' for pointing out the oversight.

update 26/12/2022 v2.1
- added slight curve and color tweak with 3dmigoto
- reduce flare reflections chrome, etc in cockpit view
- added very slight luma sharpening

  tweaks are done with 3dmigoto

If you do not like specific tweaks please see 'further tweaking'

3dmigoto shader tweaks:

- reduce strength and whiteness headlights car avatar and npc
- reduce black borders horizontal replay screen but keep selection visible
- reduce artificial sun globe on tracks
- more presence clouds
- reduce brightness upper part cockpit
- reduce glass tint effect in cockpit view

- 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.
