brother, there is possibly one shot where you hit him in the chest and it didn't register. Or your mouse coulds be double clicking and you havew to up your debounce timew or its time for a new mouse. We can't tell from that vid whether it was the game or not, and we have no idea where the other guy was actually aiming on his screen. You can't just look at the model and say he was missing. You also have to understand that things happen that your eye can't see. So never listen to people telling you that you won't notice a high hz on a low frame rate monitor, as if it matters brother, as if that changes the reality of you mouse and kb still reacting faster lol. We can't conclude anything from your video except that you should really test your mouse.
I remember a few years ago I had a logitech g203 basic rpg gaming mouse I had for a while. I thought my pc was being hacked becau8se when I played chess in a browser I was having problems dragging and dropping. I found out it was my mouse. And any pro gamer will tell you, the first thing to go on a mouse is the button, and you won't even realize it. Except in certain situations.
Now is this game tick sensitive? Of course its 64 players with insane graphics. has any game ever done it better? nope.
I've also noticeds in this game, I sometimes can't quickly throw or launch or nade or switch to the launcher fast enough, I thought it was my keyboard, but its the game that makes you pause. kind of annoying but I wouldn't attribute that to net code. code...yeah.
But when we talking net code specifically we getting into the competitive aspect, and that is a whole different ball game. You can't trust your eyes.
