Another tip that maybe helps...
If your modem has the ability to prioritize packets like ACK,SYN,FIN,RST....
Prioritize ACK and SYN...it helps me to lower jitter...games sends many ACK and SYN packets.
 
From wikipedia.org...
 
<< Connection establishment:
To establish a connection, TCP uses a three-way handshake. Before a client attempts to connect with a server, the server must first bind to and listen at a port to open it up for connections: this is called a passive open. Once the passive open is established, a client may initiate an active open. To establish a connection, the three-way (or 3-step) handshake occurs:
SYN: The active open is performed by the client sending a SYN to the server. The client sets the segment's sequence number to a random value A. SYN-ACK: In response, the server replies with a SYN-ACK. The acknowledgment number is set to one more than the received sequence number i.e. A+1, and the sequence number that the server chooses for the packet is another random number, B. ACK: Finally, the client sends an ACK back to the server. The sequence number is set to the received acknowledgement value i.e. A+1, and the acknowledgement number is set to one more than the received sequence number i.e. B+1. At this point, both the client and server have received an acknowledgment of the connection. The steps 1, 2 establish the connection parameter (sequence number) for one direction and it is acknowledged. The steps 2, 3 establish the connection parameter (sequence number) for the other direction and it is acknowledged. With these, a full-duplex communication is established.>>
 
 
.................................................................................
 
Connection termination:
 
The connection termination phase uses a four-way handshake, with each side of the connection terminating independently. When an endpoint wishes to stop its half of the connection, it transmits a FIN packet, which the other end acknowledges with an ACK. Therefore, a typical tear-down requires a pair of FIN and ACK segments from each TCP endpoint. After the side that sent the first FIN has responded with the final ACK, it waits for a timeout before finally closing the connection, during which time the local port is unavailable for new connections; this prevents confusion due to delayed packets being delivered during subsequent connections.   A connection can be "half-open", in which case one side has terminated its end, but the other has not. The side that has terminated can no longer send any data into the connection, but the other side can. The terminating side should continue reading the data until the other side terminates as well.    
It is also possible to terminate the connection by a 3-way handshake, when host A sends a FIN and host B replies with a FIN & ACK (merely combines 2 steps into one) and host A replies with an ACK.  
 
..........................................
 
So in both situations ACK and SYN packets must have big priority.
 
And if your modem/router has the ability to set up TCP Timeout  set it at 90 ms.....your console/server doesn't need to send FIN or RST packet to close the connection....
Your modem will "drop"  this connection....so less packets travelling....less internal jitter.
 
Think of that....
You shoot a person...you send a packet that  a "bullet" leave from you (ACK)....server confirms to you with ACK/SYN  that "really" you shoot a bullet....now your router must send a FIN packet to close this connection and after a ACK packet!!!!
If your modem can drop these connections it doesn't needs to send packets...less traffic to your network and much easy to handle that.
 
I hope i do not confuse you.

With this line everyone can be "pro"!!!

I agree with @bbursley  when people keep buying COD....they think that people like these "system" of matchmaking...SBMM it doesnt matter what skills you have in aiming ..reactions and so on...algorithm decide if you will "win"...how can realize that..it is pretty easy..in one match with one magazine you kill 3-4 enemies with 2-3 bullets....and the next games you hit a hole magazine in one enemy and he is keep running!!!!
The problem isn't Netduma or your connection ..it is the game....that's why in previous COD's the configuration was needed was simple and 100% working....find your speeds..adjust bars to eliminate bufferbloat....adjust geofilter...and thats it...you will play sollid games 90-95% of the time.
In the topic there are so many configurations but i think no one can say that is working all the time....it is just "lucky" to have good games....algorithm SBMM decide it for you.And for sure it doesnt matter for this game what is your ping...even players with really low ping has problems and crap games!!!...."Ping is king" is for old COD's not for this.

Cold war and SBMM games are just shit, end of story really. Doesnt matter what you do, only answer is to join bot players or reverse boost.

Hey Testers,
We've got a new R1 beta firmware for you guys to dig in to!
https://www.dropbox.com/s/8z4kcynmo3glplp/DumaOS-R1-3.0.207.sig?dl=0
We'd suggest a factory reset after the upgrade to ensure you're starting from a clean slate, let us know how you get on!
Change log:
Fixed issues with Adblocker and Connection Benchmark Fixed issues where the GUI doesn't load properly Fixed issues with Wi-Fi backend Fixed other issues with Network settings Added stability improvements to QoS Fixed Device Manager crashing issue

Many of us has the same thought as me...i am not "pro" player.....i play cod over 10 years..i am not noob..my accuracy is very very good the same the reactions.
I know sometimes i will play with players better than me...but every time?????
It seams that every time i was playing in a "competition"..others kill me so easy and i have to try hard to kill them...etc. they plays with suppressor in their gun and get kill so easy in a distance.
It feels that you play against players and against the game it self.
So with other persons from Openwrt we try to do something better....we are not network "gurus"...and find some usefull things to make it plays better....i say better...not perfect.
I see players that in every cod they have perfect connection.
We dont have the networking knowledge to do better things...someone will say that the problem maybe is my low bandwidth connection..i have 16000Kbps down and only 800kbps for up....but i see that people even with gigabyte connections suffer from the same issues...etc. shoot first die first.
So i dont think that speeds matters ....also we find via wireshark that game uses only about 200Kbps for upload and about 400Kbps for download....so everyone has plenty speeds to run the game.
I usually play in 80ms ping..many of you play at much lower ping....but again the same thing happens.....even if you play at 80ms ping or 30ms ping......shoot first..die first.
Sooo what the hell???
Speeds doesn't matter...ping doesn't matter....
For sure that guy that has perfect connection..and you see him in Youtube in a video like "fix lag in cold war"...will suggest some "fixes" that everyone knows..but the real "trick" of course will handle it for himself sure.
It will be something else that "matters"....and this must be investigated by the company who sells "gaming routers"...not me ..the user.

It's strange cod is the only game where I get inconsistent connections but the good players I come across year after year always seem to dominate and be untouchable. They always have that connection edge where they can turn on people shooting them from behind and get the kill, people appear to be moving around slowly not reacting to them shooting etc. They obviously have some networking knowledge to be able to tweak their connection to give them this type of result year after year. Yes they are good players but how are they always on the "good side of lag comp?"
If I owned a company that marketed routers to gamers (where the majority of people played cod) I would do everything I could to make the users of my device have the best experience possible gaming. I would offer different predefined tweaks within the settings (qos schedulers/disciplines/latency etc) letting users find what works best for them giving them an enjoyable gaming experience. I don't see this as cheating as these options are explorable with different firmware, people just don't have the knowledge to do it themselves.

I agree with N3cro... Cod is alone category by It Self.. Something that has no logic May give you perfect game experience. 

Thank you very much i start working on it.
