long story short ps3 update 1.03 made lag compensation 5x worse for me so i done the following steps to attempt to fix it:
1. Changed mtu packet size to correct amount
2.Used ethernet cable
3.gave my ps3 a static ip address
4.forwarded ports towards black ops 2 for ps3
5. used dmz on my ps3
6. changed search preferences to "best"
after all of this i still experience extremely bad lag compensation! my download speed is 10mbs since i dont need fast internet, what else can i do or is this even helping?
