@Srksii I mean it would be interesting to know cause a mate of mine whom I regularly play with said that sometimes the in-game crosshair is slightly displayed from the actual center and that's the reason (probably at least) why in some rounds your hipfire hits so well and sometimes out of a 30 round Flatline mag only 2 or 3 shots hit even though the enemy doesn't really have great movement.
On one side I find that a little hard to believe cause IF that were the case it'd be a thing done on porpose by the devs.
But on the other thing maybe it IS true cause they just did some funky programming. By now I think of almost anything as possible so who knows.
But I sure as hell won't risk my 2500+hrs account for such an experiment so I'll just abstain from playing with such stuff activated.
