for some reason whenever i play halo3, odst, or halo reach, if i am in a campaign game with other people online playing with me, or if im in a firefight game online with people with me, my controls are lagging. its hard to explain but my controls do not respond instantly when i move the stick or press any of the buttons. it feels like my character is ice skating. if anybody knows how to fix this, please tell me. its making it so i cant play all the benefits of halo reach.
