First off, I'd like to state that I'm not trying to bash any of the people on here trying to give suggestions, because I really do appreciate the effort, but as of late nothing has seemed to work. I'll explain.
First off, here's my connection:
I'd also like to state that I have an above average router and modem, the cables I'm using are of good quality, I've done all the mumbo jumbo like opening ports, creating static IP's, even tried playing on my phones 3g connection a while back, etc, etc, and just recently changed my DNS server to one that is according to some program, 3.8% faster. Sweet.
Anyway, the other day I decided to get back on MW3 after a fairly long leave of absence (which was great btw, you guys should try it, lol), and, like usual, was getting a fairly extreme amount of lag. I happened to stumble upon a thread on here that was talking about the MTU setting, and decided to mess around. According to what they said, the highest I could get my MTU without defragmenting was 1472, and apparently you need to add 28 to that for whatever reason and that's 1500 for my optimal setting. However, I read someone was having some luck with the MTU at 1400, so I gave it a try. Now, I wasn't unkillable by any means, but I was going like 30-3 in FFA's just running around. It seemed more fair, ya know, if I didn't get the shot off, or missed, I died, and if I did I won. Crazy concept, I know, but it seemed to be working fine. The guns didn't have an unusually high amount of recoil, people weren't taking hitmarker after hitmarker, I wasn't dieing from around corners, people didn't seem to have better than MLG reaction time, etc etc.
So I though I fixed the lag. Well, the next day I get on and it's crazy again. Same 1400 MTU, but I can't win a single gun fight. So I bumped it up to 1472, and it was still insane.
Then, I tried the two extremes, and I have video of what those two games were like, and here they are:
These two games are on PS3, but I have both consoles, and there is obviously lag on both.
First is with the MTU all the way up to 1500, which is apparently my optimal setting:
Second video is with it turned all the way down to 1360, which apparently you can't even do on xbox, lol:
Notice that in both games I had zero time to react, and the other team had enough time to get 3 kills in each final killcam. Keep in mind these were back to back games, but in competely different rooms because I had to quit the game to set this up.
Now this was just a couple days ago on MW2. It's on xbox because the PS3 version is hacked beyond all recognition.
And that's how it usually runs, and it's without having to tinker with anything.
