Crysis Tweak Guide
I've finally completed the Crysis Tweak Guide, and while there are no magic tweaks or quick fixes, the guide covers all the in-game settings in detail, and provides descriptions for all the major advanced command variables which allow you to customize the game to suit your needs. There are plenty of comparison screenshots and handy tips spread throughout the guide, so if you're patient and willing to experiment, the guide will reward you well.
