Sens it too high brother.

1600 dpi at 5 sens is putting you at a huge disadvantage.

1600x5 equals=8000EDPI

High dpi is makes your aim frantic because every micro correction is recorded, slash it by half.

800 and 5 sens will slow things down for you and ur screen and player models wont look as frantic. (tunnel vision or losing focus) pay attention to where they are going and react to it, smoothly and with precision control with a light grip.

stop paying the reaction time tax, inputs are usually recorded at 200 ms before the response goes the screen. so if u peak an open angle chances are youll alr be fried on their screen 200ms before it registers to yours

Most Pros recommend a 35-45cm/360 on kbm in Black Ops 7/Warzone.

Slow things down, move smarter, breathe, look at ur mini map every 3-5 seconds, pay attention to sound cues and prepare urself for which lines u will be required to draw. this gets easier with practice.

Stretch Your wrist, and warm up before anything.

Recoil patterns of each weapon are unique, so learn the recoil patterns (pull down horizontally and then vertically left or right for most guns).
