Lol, I work in IT also. But I trust you as you said you have tried everything and had a fellow industry member check it out.
Hopefully they will resolve the bug for you soon.

The issue appears to be within the games coding rather than anything else. You can view the issue in detail at the following link:

Keep in mind this is split screen offline play. Imagine this with any form of latency and you're asking for trouble. The funny part is the game ran fine before the theatre mode was enabled again. It got even worse when Live Streaming went live weeks ago. And upgrading my router made it worse and I'm using the Asus router with A/C technology but its wired to my Xbox. My ISP noticed a line issue I complained about and upon fixing my internet got even better again and the lag on Black Ops 2 became worse. I ditched my modem for a new Motorola Surfboard 6141 and again my speeds and ping improved yet Black Ops 2 got even worse.
Seems odd doesn't it? I notice the smallest form of lag and now its just as the video showed. Less lag on every game except Black Ops 2. I can go back to Modern Warfare 3, Black Ops 1 and see minimal lag. Modern Warfare 2 is nearly lag free and runs better than any other CoD in history.
Sorry for the wall of text. Lol. I'm just glad it runs great for you. Although it does make this whole situation even stranger. Maybe location? I'm from Illinois and I notice more lag than a friend from Florida. I'm paired with a lot of Canada players and a bunch of random Mexico players. I swear Mexico connections are sub par but that's a whole different conversation.
Sorry for the thread hijack.
