I have been playing around with SweetFX ever since the Realmware Color Tweaker was killed off by DICE, R.I.P color tweaker :_;
Anyway, I have been trying to replicate the results of the color tweaker using SweetFX so that BF3 looks as it did with the Realmware Color Tweaker installed.
I have managed to get it looking near enough to that standard, it's not as good but it's near enough and looks a hell of a lot better than standard BF3 anyway
Here are some screen shots of before and after.
The top picture of each screenshot is standard BF3, the one below is with my SweetFX settings.
These are the settings I changed in Sweet FX
USE_LIFTGAMMAGAIN = 1
USE_TONEMAP = 1
SMAA_THRESHOLD = 0.20 // USE_SMAA_ANTIALIASING
SMAA_MAX_SEARCH_STEPS = 98 // USE_SMAA_ANTIALIASING
SMAA_MAX_SEARCH_STEPS_DIAG = 16 // USE_SMAA_ANTIALIASING
SMAA_CORNER_ROUNDING = 100 // USE_SMAA_ANTIALIASING
pattern = 1 // USE_LUMASHARPEN
RGB_Lift = float3(0.950, 0.950, 0.950)// USE_LIFTGAMMAGAIN
RGB_Gamma = float3(0.900, 0.900, 0.900)// USE_LIFTGAMMAGAIN
RGB_Gain = float3(1.000, 1.000, 1.009)// USE_LIFTGAMMAGAIN
Saturation = -0.10 // USE_TONEMAP
Defog = 0.010 // USE_TONEMAP
FogColor = float3(0.00, 0.00, 1.00)// USE_TONEMAP
Vibrance = 0.30 // USE_VIBRANCE
