Change your video settings without crashing the game (borderless windowed)
Make sure your game is closed before doing that.
Go to where your Modern Warfare 3 is installed and go in the players2 folder.
Then open plutonium.cfg with the notepad to edit it.
Find r_displayMode and change it to be like this (you can use ctrl+f to search for it):
seta r_displayMode "windowed (no border)"
