So this is my .cfg

sys_spec_objectdetail=4
sys_spec_particles=4
sys_spec_postprocessing=4
sys_spec_physics=4
sys_spec_shadows=4
sys_spec_texture=4
sys_spec_water=4
sys_spec_gameeffects=4
sys_spec_shading=4
sys_spec_VolumetricEffects=4
r_motionblur=0
g_radialBlur=1
r_MotionBlurShutterSpeed=0
r_MultiThreaded=1
cl_fov=75
pl_movement.power_sprint_targetFov=75
sys_physics_CPU=5
gpu_Particle_Physics=1
r_displayInfo = 1
g_skipintro=1
i_mouse_smooth=0

What should i add, to improve quality per. performance level ? The best balance between good performance and maximum quality.

That has a very large amount of configuration options, might wanna take a look at that if you're wanting to experiment.

; crysis 2 HD - autoexec

::V 0.03::
;custom autoexec.cfg
;[*]commented non supported cvars
;[*]improved detail render distance
;[*]improved environment texture update interval
;[*]improved maximum onscreen particles and emiters
;[*]Detail View Distance Ratio decreased
;[*]Decreased HDR grain ammount
;[*]Rain/deffered max viewing distance improved
;[*]reduced ammount of beam slices to 225
;[*]HDR range adaptation max adaptation increased
;[*]decreased maximum dynamic-lights (was eating to much fps)
;[*]disabled vegetation terrain-color blending (free 1 fps, and looks crispier)
;[*]decreased physics distance, but increased viewable distance
;[*]updated "viewing distances" to far was eating to much fps
;[*]enabled "HW occlusion test for objects"
;[*]updated "size of LOD 0 GSM area" (increased)
;[*]enabled "cast shadows from terrain"
;[*]updated "maximum distance of global illumination"
;[*]improved lod distance on objects
;[*]corpse distances improved and they stay on the field longer
;[*]"Sprint speed scale when not using a nanosuit" updated (a bit faster)
;[*]"time between hits to start regeneration" decreased, improve regen time
;[*]player regeneration rate goes a bit faster now
;[*]increased the "fade to death" (black fade after dead) time
;[*]player cover edge detection updated (should enhance the cover system)
;[*]player Inertia updated
;[*]"General speed scale when not using a nanosuit" updated (faster)

i didnt make it myself i got it off the interweb

Ok can anyone give me some vital .cfg tweaks that really take a effect in quality, that my eye can see it in the actual game? Not just some bunch of .cfg tweaks, most of them useless. And can anyone tell me what lines to put in the .cfg file to really improve performance in the game with less impact on quality. I disabled motion blur for now. Are any codes that improve performance?
