Hello, today I am going to tell you how to remove the Depth of Filed effect in the game.
For many, the effect provides an additional level of immersion in the hazy dream-like nature of the game, for others, however, the developer's choice to hard-lock the setting without allowing the player to change it is a game-breaking head aching experience. If you are such a person, this guide is for you.

Go to the local folder (right-click on the game in the list ->propreties->local files->browse)
Go to ...\common\Dream\UDKGame\Config and open UDKSystemSettings.ini with your notepad
find the line with DepthOfField and change it to DepthOfField=False

Enjoy!

PS: There are a number of other useful settings in the file and other files inside the folder. If you feel confident, you may change those to your liking as well, but I won't recommend it, unless you know what are you doing
