Just for interest...dont all Cod's have monitor match at 0% ? Do Bo2, Bo3 and IW differs from eachother?
Modern Warfare 1, 2 3, World at War, Black Ops 1, 2, Ghosts, and Advanced Warfare have 0% match. Black Ops III and Infinite Warfare are different. It probably has to do with how they changed the FOV system. In Black Ops III they changed it to 16:9 FOV and in Infinite Warfare it is 16:9 but they seem to be using "cg_fovscale" instead of "cg_fov"/"cg_fov_default". With fovscale it is a multiplier, so setting 106.26 fov would be 1.32825 (106.26 / 80). In previous games fovscale would scale aim down sights as well instead of just changing the hipfire fov but in Infinite Warfare it just changes the hipfire. Also after all this, the fov apparently isn't even correct to what you set it as. So I think these changes messed up the ADS sensitivity along the way.
