(adsbygoogle = window.adsbygoogle || []).push({}); As I have been browsing around the social networks of NGU and YouTube, I have heard a fair amount of complaints about the lag compensation feature in MW3. To explain to those of you who don't know what this is, it is how the game will attempt to balance the connection by creating lag for the players with a better connection, and is why you will sometimes see that everybody in the lobby has a 3 bar connection, and cannot tell who the host is. This feature is in Black Ops too, but it was much less noticeable. The problem with the compensator is that it needs to be done almost perfectly for it to be effective, which is not the case in MW3.This causes the people with lesser internet connection to have the normal amount of lag they experience, while the better connected players pretty much get screwed over with artificial delay that they truly should not have.

Here is a video that shows it off pretty well, and the scenes may be familiar with those of you on the bad side of lag compensation:



After seeing this video, I decided to try and find a way to counter this lag compensation, so that I could possibly be on the good side of it, and have a good advantage. I figured that lessening my connection would be the hard, but helpful way of getting to the strong side of the compensator. I did this by going to my router settings, and going to the QoS(Quality of Service) page under the Gaming tab, and setting my connection to it's lowest setting specifically to Modern Warfare 3's ports, and by God, it worked. I do have a more noticeably lag, but I don't have nearly as much of a delay against other players. For instance, when I run around a corner, I have less delay, giving me more time to react compared to the other guy, and after only 3 or 4 matches online, I can easily see the difference made.

Here is a picture of my QoS screen:

Here are the specific Mw3 Ports from Portforward.com:
TCP: 27014-27050
UDP: 27000-27030
Both: 3074-3074

Here is a video I found that helped me figure some of this out, and change my QoS


Have fun taking advantage of other people! :y:

If you have any questions, quote or preferably PM me! Good luck!


[EDIT]
I have discovered another way via Twitter, and some tweaking with my router settings, and it has the same effect, and sometimes better than the QoS method for those of you without it. It is editing your MTU. Your MTU is the Maximum Transmission Unit that is sent as information as a 'packet', and the default is 1500, but some routers can do more, and can always do less. This pretty much changes how fast your internet information is relayed through your router.

What I did was lower my MTU by 10. Then I played a few games to decide whether or not it gave me the benefit of Lag Compensation. If it didn't, then I lowered it by another 10, and so on. You pretty much want to guess and check, too low will give you moderate NAT, and keep you from connecting with some people, and too high won't give you the benefit.

The MTU setting is on the first page of my router page, so it should be on a main page of yours. If you want, I can put a picture of it up, just let me know! :y:

Lolz and this would explain alot :/
HOPE TO GOD they remove this or am never buying COD again as long they keep this system. Worse idea ever put into COD.

Yeah this doesn't really fix a 100+ mb connection XD

I put a new fix up if you actually want to try it. :lol:

Got it up :y: sorry it took so long.

my MTU is at 1492 so i move it to to 1482?

What should I put my MTU at for maximum laggage?

Hold up hold up! How do you know those port numbers from portforward.com are the real ones and are you positive they work in reducing lag? I'm just asking because the ports you listed and the ones from Activisions support site are 2 totally different sets of ports

Very good thread...2 quick questions for ya. I already have a moderate NAT, but that wouldn't effect the actual lag compensation correct? And what MTU setting did you end up on? I keep going lower and lower, and no matter what I seem to have a 4 bar connection still. Thanks in advanced!

time to try it...hopefully i dont fail

Changing QoS priority for an ethernet port probably will not do anything noticeable in the game. Unless you have 5 other people using the router at the same time you are playing then telling your router to not prioritize your ps3 will do nothing to slow it down. That just tells the router what device gets more packets sent at a time. If you have just your ps3 going then telling the router to make it a low priority will do absolutely nothing. Changing the MTU is an interesting Idea though. I will give this a try and post my results.

If you are wanting to just lag your connection no matter what your speed, you can just download nettools and use the UDP flooder. Search for it on NGU, it has been posted as a lag switch although it really isn't practical as one. You could use the UDP flooder in the lobby to make sure you don't get host. This will also tell IW that you have a shit connection and adjust ping's in the lobby accordingly to "make it fair" for you. Then when the game starts you just turn it off and now you have everyone handicapped because IW thought your connection was shit but now you should be half the ping as everyone else, giving you the advantage. This is just my theory, I'm not sure if it will work but now that I'm thinking about it I will give it a try.
