(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:

To find the right MTU, you pretty much need to lower it until you can tell that it works.


Just put it lower and lower, just not to the point where you can't connect. I haven't really put it as low as possible, because there is no need for me to do it.


Well I just used those because they were the first ones I could find, and they seemed to work, but you can try those and post your results! :y:


Your NAT type is just how you can connect to people, but you might already have the benefit of the Lag. And I also have a 4 bar right now most the time, its just how your connection matches up with other people's.

Both work,,, I just think MTU is not as complex. Quality of Service seems to work better, but I am using MTU for now. Thanks

wen i put in 27000-27030 says vaue out of range any ideas?

Isn't like 1500 the max? It is for my Netgear router anyway.

Uh, well try to find different port numbers for the game then. Someone said that Activision has some for their game. :p

I think he's talking about ports.
