Remember COD4 and COD6 cap is actually lower than that of CODWAW, it's just that in CODWAW when you go over the cap you get locked - in COD4/COD6 when you go over the cap it'll just jerk and sputter. People would occasionally get locked up in CODWAW from very laggy games, in CODMW2 you'll just get sputtery. Mode 1 is really for good connection or less players on the server, you'll have to revert to mode 2 if mode 1 is sputtering. Mode 1 is close to firing at the COD4/CODMW2 cap. Remember, CODWAW actually had a higher cap than COD4. Same goes for CODMW2 unfortunately.
