if I play Treyarch's COD games,the game becomes super lag even in menus and single-player.I think their engine has a bug.Two COD games the results THE SAME!!!!!.......If I see the sky or the ground in the game it has 100% no lagging and it was looking realistic,but it was very lag if you see places other than the sky or the ground.

My theory is if I play too long that might happen and it was like permanent lag.

I love Treyarch make COD but the lag bug is the one I hate!!!
