They have acknowledged it. It's called probation.
The reason for probation is to stop people, mainly hosts from backing out - in other words they know their games lag, and lag compensation is retarded so instead of trying to fix it, they want to penalise you for leaving games early.
My advice, back out the game as often as you want, probation is only 5 minutes long. Hardly worth worrying about. I'd rather take 5 mins out to grab a drink or whatever, than stay in a lobby as the host constantly going negative because 12 players connections are lagging me like crazy.
Why aggravate yourself any further? Just stop playing the game because it will not be fixed. I would love to enjoy the game I paid for but at this point I realize it's impossible and I'd be fighting a battle that will never be won. Treyarch screwed up majorly and honestly the game has gotten worse every time I upgraded my internet equipment.
1.) Router - Got worse.
2.) ISP upgraded lines - Got so bad it's not even funny.
3.) New Modem - Really, got worse?!?! How is this possible?!
BTW: Everything else got better or stayed the same. My Ping improves, speeds improved. No packets lost. Yet CoD says it got worse? I guess pulling host all day means I should lag huh? Shove it, Treyarch.
I know my connection is fine , and its a problem with the game as the OP states. i posted a video a few posts up showing exactly what the problem is.
But treyarch many people on here that believe that there isn't a problem.
This is far worse than lag comp. It seems as though every player in a match is lagging. There are times when i don't host! and the killcams show me not shooting.
