tells you there....but basically
System.cfg
This file doesn't exist by default, so you need to create it by going to your
\Program Files\Electronic Arts\Crytek\Crysis directory, right-clicking on an empty spot and selecting 'New>Text Document'. Then rename this .txt file to
System.cfg (not System.cfg.txt). By default Crysis looks for the presence of this file each time it starts, and if the file exists and contains valid commands, they will be automatically executed when the game loads up. As such, this file is the perfect place to store most of the commands you wish to apply to Crysis at startup.
The format for entering a command in a config file is different to that of commands used in the console. If you want to disable motion blur for example, the console command is
r_motionblur 0, but when entered in the config file, it needs to be
r_motionblur=0, and every command needs to be on a separate line.
