If the aforementioned solutions do not yield results, players must look toward Windows display handling. Modern Warfare III often defaults to "Borderless Fullscreen" mode, which can introduce input lag and synchronization issues.

Furthermore, players should check the game’s configuration files. Occasionally, the game creates a config file (often found in the players folder within the game directory) that contains a command line explicitly limiting the frame rate (e.g., com_maxfps 45 ). Editing this file with a text editor and removing or raising this value can manually force the game to unlock its frame rate.
