Modern Warfare 3 PC Tweaks
We wouldn’t go into much detail on how you can tweak the video options in-game to get a performance boost, because they are pretty self-explanatory and you can reduce them all the way down to increase frame rates.
If you aren’t content with what you get after tweaking the in-game options, edit your Modern Warfare 3 config file.
Where To Find Modern Warfare 3 Config File
C:\Program Files\Steam\steamapps\common\Call of Duty Modern Warfare 3\Players2
You will find two types of config files in this folder. One Config.cfg contains all tweak variables for singleplayer while config_mp.cfg contains all tweak variables for multiplayer.
You can open these files with any text editor and edit the corresponding variables. Any Cod veteran with previous experience would know this.
Change the corresponding variables and save the file. Start the game and enjoy.
Note. Before making any changes to your config file, it is always recommended that you save a back up of the original config files so you don’t mess up anything.
