how can i add codes for Example "CL_FOV = 70" ?
and other
and where the file ""autoexec.cfg"" can i find it !!

In the crysis folder...

c - prog files - electronic arts - crysis 2.

:)

no .. it's no there !
only System.cfg
:(

Strange. Try to make a new file in the note block, add your configs and save as autoexec.cfg

make a new file named autoexec and save it as .cfg

Add whatever values you wish to use there. Put the .cfg in the same root folder as system.cfg

Here's mine for example

con_restricted = 0
r_DisplayInfo = 1

sys_spec_shading = 4
sys_spec_gameeffects = 4
sys_spec_objectdetail = 4
sys_spec_particles = 4
sys_spec_physics = 4
sys_spec_postprocessing = 4
sys_spec_shadows = 4
sys_spec_sound = 4
sys_spec_texture = 4
sys_spec_water = 4

g_skipintro = 1
r_DrawNearFoV = 70
cl_fov = 70
pl_movement.power_sprint_targetFov = 70
r_DepthOfField = 1
i_mouse_accel = 0
i_mouse_accel_max = 100
i_mouse_smooth = 0
sys_physics_CPU = 3
r_AnisoPasses = 4
r_Beams = 4
r_ColorGrading = 3
r_Driver = DX9
r_DepthOfField = 1
r_EnvTexResolution = 2
r_FSAA_quality = 2
r_FSAA_samples = 2
e_lod_ratio = 6
e_lod_min = 0
r_PostMSAA = 4
e_shadows = 1
r_ShadowBlur = 1
r_SSAO = 3
r_MultiGPU = 0
cl_crouchtoggle = 1
r_HDRBloomMul = 1
r_HDRBrightLevel = 0.5
g_useHitSoundFeedback = 1
r_MotionBlur = 1
r_MotionBlurShutterSpeed = 0.0001
r_MotionBlurMaxViewDist = 16
r_TexturesFilteringQuality = 2
r_UseEdgeAA = 8
r_VSync = 1
r_TexMaxAnisotropy = 8
r_TexturesStreaming = 0

Does anyone know what's the difference where I put the values, it seems that there are three options, either game.cfg, system.cfg or autoexec.cfg?

exactly my problem!

how can i add codes for Example "CL_FOV = 70" ?
and other
and where the file ""autoexec.cfg"" can i find it !!

C:\Users\<>\Saved Games\Crysis2\game.cfg
Once you've edited it, set the file to 'read only'.
