Warzone Optimzation removing Stuttering FPS drops

You will find an .ini file called "adv_options.ini" which you need to edit. The exact location of the file should be C:\Users\\Documents\Call of Duty Modern Warfare\players\adv_options.ini.



Open up this file, and you will see "VideoMemoryScale = 0.85". Note that this number can differ case by case, and is the root cause of the bug. 0.85 is a scaling factor for how much of your available VRAM is going to be used when running Warzone.
