Dirt 2 the odd man out in codemasters rally series.
If you like your rallying serious then this one is not
for you however if you like it with some panache, bon ami
and a top notch soundtrack then you are in for one wild ride...

Some of the post processing and effects in the game are modified by
altering the existing effects.xml and some other existing gamefiles.

3dmigoto shadertweaks:
- reduce overbright road
- reduce tint windscreen in cockpitview
- remove sky sun grey haze and reduce overbirght sky
- remove lensflares
- reduce bloom
- reduce overbright car chasis

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

- updating (from v1.0)

remove the follwing files and folders:
SweetFX
dxgi.dll
SweetFX_preset.txt
SweetFX_settings.txt

then follow the install procedure.

- install

The following folders in this package contain files that will overwrite
the existing gamefiles (best to make a backup of the original files first)
cars
effects
frontend
postprocess
tracks

Copy the contents of the zip file to the install folder of dirt 2,
the folder which contains dirt2_game.exe with exception of the folder(s):
original - contains the original files (use to restore game files, just in case)

- 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 dirt 2 (32bit versions)
d3d11.dll
d3dcompiler_46.dll

then copy the d3dx.ini and the folders ShaderCache and ShaderFixes
from the zip file to the install dir of dirt 2.

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

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

0d2584675f9c6252-ps_replace.bin

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

- tested

Tested with version 1.0.0 of dirt 2 on win 7 / nvidia 1050gtx ti
See screenshot(s) for settings game.

- performance

3dmigoto  gpu usage (game capped at 60.7 frames) plus fast sync
without - clock 974Mhz gpu usage ~65%
with       - clock 974Mhz gpu usage ~68%
approximately 3% increase (1050gtx ti on win 7)
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:
288DAC12B6A06F64-PS_REPLACE.txt

Has a remark on the top line:
// remove lensflares

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

8E6AA2AA02963934-PS_REPLACE.txt

and if compiled remove:

8E6AA2AA02963934-PS_REPLACE.bin

then restart the game.

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

- tips

If you need help with getting xlive to work,
look for but be careful, the following files:
dbxLive32.dll
msidcrl40.dll
xlive.dll
xlive.dll.cat
xlivefnt.dll
xliveinstall.dll
xliveinstallhost.exe

and if needed put them in the install folder of dirt 2
where dirt2_game.exe is located.
