Toggle SweetFX on/off = `(~) = tilde key 

Extract SweetFX into the following directory = \Steam\steamapps\common\KillingFloor\System\

Only works with "Direct 3D 9.0" rendering, "Direct 3D" and "OpenGL" not working...

I've tweaked this preset with DEFAULT in-game Gamma, Brightness, Contrast and it still didn't look right
the game has some horrible default values, I've changed them as follows

*Gamma = 0.80
*Brightness = 1.00
*Contrast = 0.80

Feel free to play around to adjust to your own liking, it's extremely flexible.

Also tweaked preset with "HDR BLOOM" disabled, it's absolutely horrible looking, use if you wish lol...



*Update*

Seems some folks have issues if they have in-game AA enabled... if you do have issue, 
disable in-game AA, then relaunch the game
