Après pas mal de temps à bidouiller les fichiers, je suis parvenu à un résultat tout à fait satisfaisait : il n'y a plus cette effet jaunâtre, les couleurs sont plus vives, l'effet métallique est plus réussis... bref, c'est plus joli, plus réaliste, et après divers test il s'avère que c'est beau quel que soit la météo (alors qu'avant le jeu devenait trop sombre par mauvais temps, par exemple).

J'utilise la dernière version du mod. Maintenant, sa configuration se fait via deux fichiers : GEM_settings.txt et SweetFX_settings.txt.
Voici mes paramètres :
GEM_settings.txt

// Set to 1 for ON or 0 for OFF

- define USE_FXAA_ANTIALIASING 1 //[0 or 1] FXAA Anti-aliasing : Turn off when fps drops
- define USE_GEMTRUECOLOR 1 //[0 or 1] GEM : Applies GEMShader with true color look. !!Only use one GEMShader!!
- define USE_GEMCINEMATIC 0 //[0 or 1] GEM : Applies GEMShader with cinematic look. !!Only use one GEMShader!!

// -- General settings --
- define GBlur 2.0 //[0.10 to 2.00] Adjust GEM-Blur (standard 2.0).

// Set to 1 for ON or 0 for OFF
- define USE_SMAA_ANTIALIASING 1 //[0 or 1] SMAA Anti-aliasing : Smoothens jagged lines using the SMAA technique.
- define USE_FXAA_ANTIALIASING 0 //[0 or 1] FXAA Anti-aliasing : Smoothens jagged lines using the FXAA technique. WIP - Currently only works in DX9 and you need to use the FXAA injector dlls.
- define USE_CARTOON 0 //[0 or 1] Cartoon : "Toon"s the image. (Interferes with SMAA, CRT, Bloom, HDR and Lumasharpen)
- define USE_ADVANCED_CRT 0 //[0 or 1] Advanced CRT : Simulates an old CRT TV display. (Interferes with SMAA, Cartoon, Bloom, HDR and Lumasharpen, and it has a very high performance cost)
- define USE_BLOOM 0 //[0 or 1] Bloom : Makes bright lights bleed their light into their surroundings (relatively high performance cost)
- define USE_HDR 0 //[0 or 1] HDR : Not actual HDR - It just tries to mimic an HDR look (relatively high performance cost)
- define USE_LUMASHARPEN 1 //[0 or 1] LumaSharpen : Also sharpens the antialiased edges which makes them less smooth - I'm working on fixing that.
- define USE_TECHNICOLOR 0 //[0 or 1] TECHNICOLOR : Attempts to mimic the look of an old movie using the Technicolor three-strip color process (Techicolor Process 4)
- define USE_DPX 0 //[0 or 1] Cineon DPX : Should make the image look like it's been converted to DXP Cineon - basically it's another movie-like look similar to technicolor.
- define USE_MONOCHROME 0 //[0 or 1] Monochrome : Monochrome makes the colors disappear.
- define USE_LIFTGAMMAGAIN 0 //[0 or 1] Lift Gamma Gain : Adjust brightness and color of shadows, midtones and highlights (avoids clipping)
- define USE_TONEMAP 1 //[0 or 1] Tonemap : Adjust gamma, exposure, saturation, bleach and defog. (may cause clipping)
- define USE_VIBRANCE 0 //[0 or 1] Vibrance : Intelligently saturates (or desaturates if you use negative values) the pixels depending on their original saturation.
- define USE_CURVES 1 //[0 or 1] Curves : Contrast adjustments using S-curves.
- define USE_SEPIA 0 //[0 or 1] Sepia : Sepia tones the image.
- define USE_VIGNETTE 0 //[0 or 1] Vignette : Darkens the edges of the image to make it look more like it was shot with a camera lens. May cause banding artifacts.
- define USE_DITHER 0 //[0 or 1] Dither : Applies dithering to simulate more colors than your monitor can display. This lessens banding artifacts (mostly caused by Vignette)
- define USE_BORDER 0 //[0 or 1] Border : Makes the screenedge black as a workaround for the bright edge that forcing some AA modes sometimes causes.
- define USE_SPLITSCREEN 0 //[0 or 1] Splitscreen : Enables the before-and-after splitscreen comparison mode.
(Oui, les AA sont activés dans les deux fichiers... dans le doute x) )
