My weapon will not respond to mouse clicks and fire for more than 50% of mouse clicks when the weapon is pointed directly at an enemy where a shot would register a guaranteed hit.

Shooting will respond to 100% of mouse clicks when missing or firing around the enemy model on either side, but will not respond to most of my mouse clicks when aimed square at an enemy, both from the hip and while aiming down sights.

This happens on every versus match with more than a handful of players, but also occasionally happens on coop. I play almost exclusively on semi-automatic fire mode with most weapons.

My build is as follows:

Intel Core i5-6600K 3.5 GHz
GeForce GTX 970 4GB VRAM

I appreciate any help or support on this glitch.
