Co-op campaign lag?

When playing either Halo 3 or 4 campaign co-op it seems to lag really bad? Even when I am hosting? I know it can’t be my connection since I get 20Mbps download, 1.5Mbps upload and I can play any other games on different platforms flawless with zero lag.

Has anyone else experienced this? Because we swapped host around and it was still happening when my friends were hosting.

I have had the same problem. I’ve only tried Halo: CE and Halo 3 on coop and my teammates have experienced lag when I’m hosting. Have no idea why it’s doing this :frowning:

This happened to me with CE and 3 so far. I just figured it was my friend’s -Yoink- internet but this makes me think otherwise. I guess we’ll see what happens Wednesday when they attempt to fix the game.
