Hey, I had just finishing installing COD4 on my XPS 1330 laptop which has a T7500 Core 2 Duo processor (2.2ghz) and 3gb of ram. I had no other programs running and just left it installing so it took about one and a half hours to finish installing. Is this normal? It seems long to me, and I don't remember how fast it was to install COD4 on my desktop with Q6600 2.4ghz and 3gb of ram either. and also for the 30sec that I messed around with COD4 it seems to be laggy when loading the activision into and when in singleplayer it loads the mission it seems pretty laggy at beginning.
