Crysis 2 Tweak Guide

Crysis 2 Tweak Guide

You can Tweak Crysis 2 either if you are having problems with the game, or to fine tune the game on your current rig.

You will find below everything you need to know about tweaking Crysis 2 with some example configurations on high end PC’s.
Crysis 2 Tweak Guide

You can either put these commands in the system.cfg file in your Crysis 2 directory. Or you can put them on command line by adding these in the launch properties of the shortcut.

You can right click on the shortcut, go to properties, and then add the command line options in the target box.

Change This:

C:\games\Steam\steamapps\common\crysis 2\bin32\Crysis2.exe

to This:

C:\games\Steam\steamapps\common\crysis 2\bin32\Crysis2.exe” +g_skipIntro 1 +cl_fov 75

You need to space and + just before you add the command line tweak to make it work properly.

Note. 1 enables the given setting, and 0 disables it. X stands for the level of settings with 1 being lowest and 3 being highest.

Where to Find Crysis 2 Config File
Go to X:\Electronic Arts\Crytek\Crysis 2 folder
Find and Open in Notepad file system.cfg
