Graphic tweaks  

Disable tonemapping

This tweak disabling Tonemapping. Tonemapping fading image. As u can see on screenshots without tonemapping game looks more contrasted and saturated. Its normal game look without postprocess effect if im right. Tonemapping affects on some visuals effect like glow.

RebalancedContrast

This tweak with my setup of graphic settings. That means its not disabling Tonemapping feature. Its rebalance of colors in general. Here u can try other settings in configuration.
