to test hit detection, i went to ranked since ranked in CW/VG/MW2 always gave me a different hit detection experience than the main game.
i can say that the game for the first time in a while in ranked feels like I'm actually hurting people can can fight back. before it felt like i would mag dump people and end up dead somehow, but for the past 2 days , i been drilling people. even pulling out kills and 2 pieces i wouldn't have been able to do this time last week.
i will keep testing this, moreso since im going to my GFs place for a few weeks and see if this holds up.
one thing i did after the factory reset and what not was go and remove all the other network things ( where it puts gaming, work at home and etc) that wasnt named gaming.
