Lag issue

Since the update (129mb) i am experiencing lag issues…

I have never had lag issues since launch
Suddenly i am having it since this update

My xbox is in DMZ all of my ports are open

Am i the only one experiencing lag??

Kinda annoying i cant play like that, and i cannot leave an match afraid of being banned from matchmaking :s since launch i have always completed my matches and never did i leave an match and i want it to keep it that way.
But if this lag is consistent then i have no other options left :s

Never mind, played couple of matches and its stable now

It’s so hit and miss.
