Alright, I know quite alot of TheTechGame community own the famous Call of Duty 4 on PC. I then came across quite alot of threads asking if they know how to fix "lag". So I figured I'd make this out to help you guys. Also, this guide was written 100% by me. I've given credit for the pics, but other than that, everything is mine.

Notes:

  • FPS means "Frames per second"

  • If you still struggle with your FPS after this guide, turn your brightness up until it becomes better & gives you a more playable FPS

  • The average older/cheaper computers run Call of Duty 4 (PC) at about 20-30 FPS - After this tutorial you can hit anything between 80-200, no matter what PC you're on (Unless it's a Vietnam War Veteran's PC)

  • Minimum graphics card you need to run Call of Duty 4 (PC) - Nvidia GForce 6150 SE (Or better, of course.)

  • If you need further help, or misunderstand anything, please PM me, or add me on Xfire: Jaykeh





Step #1 - Backing up your original Config.


Go to your Call of Duty 4 Folder, and hit "Players" - Select "Profiles" and then select your profile folder, and you'll see a file called "config_mp.cfg" simply right click that, and hit copy. Now just paste it onto your Desktop, or anywhere else which you can remember when it's located. Rename it too: config_mp_backup.cfg

It's just a place to store your original Config backup in-case you dislike/ever want to change back to the normal Config, or if anything for some weird reason goes wrong - now simply paste the config_mp.cfg into that folder for a backup!)

You have now backed up your original CFG!





Step #2 - Installing the new Config (Frame-rate lag fix)

Firstly, you want to download [ Register or Signin to view external links. ]

Now open up a text document, copy and paste all of that into it!

Now, save that to your desktop and name it "yitch3.cfg" and make sure the save-type is "all files"!

yitch3

Now you have downloaded that, Put it into your "main" folder, located at;

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

or if you use Steam...

C:\Program Files\Steam\SteamApps\Call of Duty 4 - Modern Warfare\main

Now, open Call of Duty 4 (PC), open up the console, and type in "/exec yitch3.cfg" & then "/vid_restart"

Alright, now we've done that; The best way to run this file is to insert it into your config_mp.cfg file, located in your players>profiles>(profile name) folder!

And you're done. Just restart Call of Duty 4 (PC), type into the console "/com_maxfps 250" and enjoy, you now have a solid, playable, and stable frame-rate!





Step #3 - Adding your original Config/settings back to normal (ONLY read if you for some reason want to remove yitch3.cfg / the new tweaks you have just installed!)

This is a very short process, so don't worry. Alright, firstly go to the location/folder of where you backed up your original config_mp.cfg.

Now, simply open up your Call of Duty 4 (PC) folder, go to players>profiles>(profile name) and simply just delete the "yitch3.cfg" file, and drag your old config_mp.cfg into it, and rename it "config_mp.cfg" and hit "move and replace". You have now restored your original settings/config back to it's original state.





Finally, the results; Before & After (Not my pics)



Before:

Enjoy.

Post below/PM me/Add me on Xfire if you encounter any issues.

Please note, the pictures aren't mine. Full [ Register or Signin to view external links. ] for those go to "bashandslash"/

Personally, I don't use this as I have a new Computer, but on my old Computer, I averaged 20 FPS, and then I discovered this, and I then got about 180. Which is just over 2x better than Xbox.

I now get 333 FPS constant. (Highest you can get)

Thanks, I hope I helped some of you guys out.

All depends on the graphics card, tbh.
