you can simply go into the config file and under visuals turn postfx from true to false which will turn off those postfx bad visuals. I use your file also just in case, but i think you don't need to change the postfx text file if you simply change the visuals to not use it in the first place.
"HDREnabled True" to "HDREnabled False" is a alternative to tame PostFX and disable it not @ all . . . like "PostFXEnabled True" to "PostFXEnabled False" in . . . \Steam\steamapps\common\SpellForce 3\bin_win32\configs\visuals.txt
