About this mod

fog reduction (wales), fog reduction day plus dusk other tracks
and some tone mapping (reduce black crush and saturation) plus
some relief / sharpening also uses smaa.

Permissions and credits
- description

Wrc 4, a blast from the past, this package contains some tweaks realized
with helix (a precursor to 3dmigoto, works exclusively with dx9) and sweetfx.

The fog in the game, specifically in Wales, is well a bit overbearing, plus
a separate shader that regulates fog on other tracks, are modified effectively
removing it.

Further the game does not have a gamma setting so the sweetfx tone map reduces
the rather heavy darkening and a 'poor mans form of tessellation' gives the
assets (cars, environment, etc) a bit of relief and more definition.
Note adds smaa so switch off the aa setting in the launcher (graphics tab).

Note! screenshots left side unmodified, right side modifed

- install

Copy the contents of the zip file to the install folder of wrc4, the folder which
contains wrc4.exe.

If you do not like using unverified dll's you can download helix from
http://helixmod.blogspot.com/
and place following files in the install dir of wrc4
d3d9.dll
dx9settings.ini

download sweetfx from
https://www.guru3d.com/files-details/sweetfx-shader-suite-download.html
rename d3d9.dll to d3d9sfx2.dll and copy it to the wrc4 folder.
then copy shaderoverride and sweetfx folders from the zip file to
the same dir aka folder plus the files SweetFX_preset.txt and SweetFX_settings.txt.

Note:
dx9settings.ini of helix contains the name of the linked proxy dll
(in this case sweetfx).

- verify

To test the fog reduction you will have to start and the restart
the game without the d3d9.dll example rename it to d3d9.dll.o
and restart the game (wales is the most striking example).

To test the sweetfx settings open sweetfx/shaders/main.h with
a text editor and modify the lines:

//#include "Splitscreen.h"
//FinalColor = SplitscreenPass(FinalColor,tex);
to
#include "Splitscreen.h"
FinalColor = SplitscreenPass(FinalColor,tex);

save the file and run the game you should see an vertical
splitscreen (left side unmodified, right side modified)

- tested

Tested with version 1.0 of wrc 4 on win 7 / nvidia 1050gtx ti
Note: this is a combination of sweetfx and helix (last versions,
both are no longer in development)

- performance

sweetfx / helix gpu usage
without - clock 987Mhz gpu usage ~50%
with       - clock 987Mhz gpu usage ~55%
approximately 5% increase (1050gtx ti on win 7)

- further tweaking

If you like you can compare the modified shader(s), Dumps contains
the original shader, to alter values. The folder 'shaderoverride'
contains the modified versions.
Note helix works differently then 3dmigoto please search for a
