I stalk that forum also
. I have theater turned off. Someone mentioned it might help by not having it record your gameplay all of the time if your connection isn't great. It's possible that isn't a proven statement but I turned it off anyway. I might turn it back on to see if it makes any difference now since I reset my router settings.
Actually, for me, Halo 3 and Reach are almost unplayable also with my country connection. MW2 & Black Ops weren't as bad for some reason but boy, MW3 is rated the same as H3/Reach with the dang sensitive connection/lag/host crap.
I will say, playing Big Team (16 players) in any of those games, was horrible for me.
I was addicted to H3 back in the day. Mainly Lonewolves and Team Slayer. See, at one time (about in 2009) my connection was kicking butt. I was ranking on up. Got 2 accounts ranked up to about 41 for one and a 40 for the other.........all in about 2 months time. I was pinging heads and t-bagging. lol. My shots were on the money and you couldn't out BR me. I loved it. One day, I signed on and it was like someone had flipped off the light switch. I could not get a kill no matter how hard I tried. Sadly, I finally got to a 45 and quit playing. The frustration wasn't worth it. I moved over to MW2.
I don't know what happened and my ISP said there was nothing wrong. I know something is wrong. It would be different if I never knew what its like having your shots register like they are suppose to. But I
DO know. I had the godly connection for about 3-4 months (out of 8 years) and it was the most awesome feeling I've ever had gaming.
That's why I try to squeeze as much out of anything I can just to get a few ms on my side these days.
