to realize this first cod use a modify id tech 3 which was use in quake 3 but later cod use the same base engine but modify and eventualy became "IW" engine (stole and use nice one IW) but if you realize IW dont use the newer ID tech engine for example ID tech 5 which is the new one has 100 better graphics than mw2 and black ops look at the good side you will be able to play even if you have a 2000 pc like me lol
