Does anyone have a suggestion for a good mod (or whatever) what actually works that successfully removes the RealIsBrown filter from the game? I'm sure that the filter exists because I'm sure I've seen it turn off one fame too soon when running the benchmark tool.

I'm not looking for another filter that competes with it by oversaturating everything and messing with bloom and HDR effects.

I've tried spyroyd's SweetFX enhancement but that just oversaturate everything, even the menu, and raised the brightness so much that black became 50% grey.

The Farcry 2 graphical enhancement suite appeared to do nothing whatsoever.

I'm willing to try out a few things and even tweak settings if you've got some suggestions, even of the things I've already tried.. I'd also appreciate any information on modifying the game my self, especially about opening the game's data files.

I hate the sepia filter they added. It bugs me too. Sadly, I haven't found a way to fix it yet.

I don't know how people mod this game. I think they use hex editors. This game is not mod friendly.

Ok, I tried the Graphic Enhancement Suite. It's actually just the SweetFX mod with custom settings.

Anyway, the settings made it look awful. Like you said, too much saturation, brightness, etc.

I've played around for several hours trying to tweak the settings just right to get rid of the sepia undertone and make it more neutral while at the same time bumping up the color without making the game look oversaturated.

Copy the files from the SweetFX mod into your Farcry2/bin/ folder

Here are the settings I found that make the game look good in my opinion:

Open the SweetFX_settings.txt file in a text editor.

The top section turns things on or off depending on whether they're set to 1 or 0.

Set them as follows:

/*-----------------------------------------------------------.
/ Choose effects /
'-----------------------------------------------------------*/

// Set to 1 for ON or 0 for OFF
#define USE_SMAA_ANTIALIASING 0
#define USE_LUMASHARPEN 0
#define USE_BLOOM 0
#define USE_HDR 0
#define USE_TECHNICOLOR 0
#define USE_DPX 1
#define USE_LIFTGAMMAGAIN 0
#define USE_TONEMAP 0
#define USE_VIBRANCE 1
#define USE_CURVES 0
#define USE_SEPIA 0
#define USE_VIGNETTE 0
#define USE_DITHER 0
#define USE_SPLITSCREEN 0

-----------------------------------------------------------

If you want to see how it looks before / after, set splitscreen to 1.

We have only enabled DPX and Vibrance. Scroll down to those sections and set the following values.

/*-----------------------------------------------------------.
/ Cineon DPX settings /
'-----------------------------------------------------------*/
#define Red 8.0 // [1.0 to 15.0]
#define Green 7.7 // [1.0 to 15.0]
#define Blue 7.0 // [1.0 to 15.0]
#define ColorGamma 1.0 // [0.1 to 2.5] Adjusts the colorfulness of the effect in a manner similar to Vibrance. 1.0 is neutral.
#define DPXSaturation 1.0 // [0.0 to 8.0] Adjust saturation of the effect. 1.0 is neutral.

#define RedC 0.62 // [0.6 to 0.2]
#define GreenC 0.59 // [0.6 to 0.2]
#define BlueC 0.50 // [0.6 to 0.2]
#define Blend 0.1 // [0.0 to 0.1] How strong the effect should be.

----------------------------------------------------------

Now Set Vibrance to .3

/*-----------------------------------------------------------.
/ Vibrance settings /
'-----------------------------------------------------------*/
#define Vibrance 0.30 // [-1.0 to 1.0] Intelligently saturates (or desaturates if you use negative values) the pixels depending on their original saturation.

Save the file, load the game, and it should remove the sepia tone and make the color look better.

If need be, use the display settings in the game to adjust brightness, contrast, and gamma. I had to bump up the brightness and contrast a bit.

I've attached a picture which shows the way the game looks before (on the left) and after (on the right).

There is no such filter. Real is brown because it's in the desert and the savannah. That is the actual colour of the game and the locations. You will notice the swamps and jungles are green as they should be.

All I can advise is to much about with the gamma and contrast settings, because the game is very dark by default and will appear much more natural if you get this right.
