lag on xbox 360 since new patch

Hi, I highly doubt this would be a result of a patch. Double check all your in-game settings/filters to make sure you are playing on a local to your country sever.

Then:

Try replacing your ethernet calbe if you use one. Also try reseting your router. If that doesnt work try a friends internet connection and if the problem goes away when you use a different internet connection coneact your ISP As it is likely a problem with your internet connection. 

Also: If you have a few people on your internet connection who are streaming video, downloading files and/or playing online games this can cause you to lag when playing your online game (and vice-versa).

I also play on the 360. I have not recieved any lag from the patch. If you frequent a server that a person from over seas plays in this could be your issue. Try to play on a different server and see if this helps

I agree with alpharavenz. I had a few Charter internet issues and resetting the router helped. And I also noticed my region settings were sending me all over the place. I changed it back to the US and it's all good again.
