How to Improve Latency for MW3 PC

Latency is also an area that you might run into trouble with. For starters, ensure your game is set to Fullscreen Exclusive for Display Mode, and check your Screen Refresh Rate. This can help improve your latency. When the game is set in Fullscreen Borderless, programs in the background can run with higher priority since the game is not in exclusive fullscreen. 

As for the refresh rate, set it to what your monitor is capable of. If it happens to be set to 60hz and your monitor can support up to 144hz, your latency will vastly improve by properly utilizing refresh rate support.

Lastly, if you’ve followed everything and are still running into trouble, don’t fret. We recommend checking on your graphics card drivers to see if they are updated. Most of the time, outdated drivers can cause plenty of performance troubles.
