TUTORIAL| Call of Duty 4 - FPS Optimization Guide

If your game is constantly lagging because your computer cannot handle some of the more stressful aspects of Call of Duty 4, then there are some things that you can do that will almost always improve your FPS ( frames per second ) and reduce clientside lag. This will not improve your internet connection and can give a 10-50 fps increase. All these commands are to be entered in the developers console during a match. The best way to go about this is to boot up the game in multiplayer and create your own match. Once the game has fully loaded you can enter some of the following commands.


To open the console, press the [`] button in the top left of your keyboard just under [Esc] called a tilde.

*NOTE - If console will not open then you need to go into Options/Game Options/ and enable console


Firstly you want to make sure you are actually getting an FPS increase, so to show your FPS open the console and type in the command:

Draw your FPS on your screen:
/cg_drawfps 1

There will now be some number in the top left of your screen, the largest of which is your FPS ( frames per second ). If the number constantly turns red then you are getting a low FPS and your computer is stressed by the game. Don't worry this isn't a bad thing, it just means that it is harder to compensate for your clientside lag. To remove this, change the 1 to a 0 and retype that command.

If your fps is constantly stopping at a number and rapidly switching between the two last digits, then you need to increase your max fps to get an increase. To change your max FPS you need this command:

Change max FPS:
/com_maxfps

*NOTE - This command limits your maximum FPS so that it will help the server from having lag confusion when your frame rate
has a sudden rise or fall. Estimate your average FPS and use that as the limit for when you play on-line. Some servers have an FPS cap and you will be notified that you need to change your max FPS to within a certain number. The warning will look something like this:


The number will of course vary, but it is simple what you must do. Use the max FPS command to change your max FPS to a number between the two indicated by the warning.


Now for some actual commands to get an FPS increase. These have to be entered one at a time.

*NOTE - The commands are in blue and what they do is in white, the ones with no explanation don't need one.

/snaps 30
/cl_maxpackets 100
/cl_packetdup 2
/rate 25000
/sm_enable 0 "Shadow Mapping" disables or enables some shadows on the world environment
/r_drawdecals 0 disables or enables some world details and extra shadows
/cg_brass 0
/r_multigpu 1
/r_cachemodellighting 1
/r_cacheSmodellighting 1
/r_vsync 0
/r_smc_enable 0
/r_rendererPreference 0
/r_skincache 1
/cg_blood 0
/com_hunkmegs 512
/r_drawsun 0


*NOTE - /r_drawdecals :: Turns off details on walls and objects, however Punkbuster will kick you sometimes for this being turned off.


After you enter all of those commands, type this last one and you are set to go:

/vid_restart


Hopefully that helped you a bit, have fun owing!

The commands i use are:

/r_drawwater 0
/r_drawsun 0
/r_drawdecals 0

/cg_fov 80
/cg_brass "0"

/cl_maxpackets 100
/com_maxfps 200 - that is the fps --Fps is stable on my comp

/snaps 20
well This should be set to either 20 for slower internet connections or 40 for faster connections, nothing else. Note this won’t help your performance everywhere because snaps also needs to be set server side by the admin, something you have no control over. - well in sG servers its set to 20 =D



--->
To show fps on the left/top hand corner
/cg_drawfps 1
<----



well these are my settings


reg,
momo

I rather download someone's config that actually improve your fps than typing all of those in the console..

Whats /cg_brass 0?

do you have to only type those in once and your good to g or do you have to type those in every time?

You have to type that once, but if some how you do lose your cod4, when you reinstall your cod4 you would have to put all of the commands back in,
So always make a backup for your profile, that is the folder called "players" in the Cod4 directory.

C:\Program Files\Activision\Call of Duty 4 - Modern Warfare

thats the default one, i dont know if u had made any changes recently that your might be different.


Holla @ ya Later,

brass set at 0 turns off the shells being ejected from your gun, only a minor boost to fps but every little bit helps.


I cant believe you all forgot this one...
r_lodscalerigid 4
r_lodscaleskinned 4

turns off textures at long range, its the biggest fps boost commands there are.

also make sure your picmips(tecture settings) are all the way down, you can do this in the menu.

Texture settings isn't that important, but it may boost your fps like +5 - +10

ill have to try these cuz i get like 70 fps-100fps
