Gears of War 2′s really shitty lag, plus trying to check the Tac/Com, yielded this fail:

And this wasn’t just a flash of discoloration.  It hung around long enough for me to take a picture – in fact, it hung around until the next round.  And that black box on the left isn’t something hanging over my tv, it’s a graphical glitch.

They really need to fix the lagginess in gears.  The lag, as well as other issues (such as the game terminating for everyone when the host leaves), would be circumvented if they let the game switch to a new host the way Halo 3 does.
