chlop: I can't seem to find the file or folder it's supposed to be in, which allows you to turn off bloom completely.
Thanks.
That's because you need to make one.
Go to the game main folder, create "Parameters" folder and create text file (for notepad or notepad+++) inside called "autoexecgame2.con"
Then you have many options to paste inside
