For those who didn`t understand

Dice is creating a new era of fps called rng fps:

Didn`t hear the tank coming? The footsteps?

It`s because there`s a 30% chance that the sound is going to render and a 5% chance it`s going to be rendered in the right direction.

Your gun reticle is in the target and you still miss the shots?

There`s a 2,33% that your shot is actually going where you aiming.

You didn`t see the claymore on the ground?

Guess what? There`s a 10% chance you`re going to see it.

Enemy soldier is almost invisible or total black skin?

There`s 5% chance your soldier will suffer a brain damage and you won`t see colors right.

Remember: it`s not a bug and your are not bad, you are just having bad luck.

OBS: CONSOLES HAS LESS RNG BECAUSE
