I want to try your App. Do I need to start the Game first and than the App or the other way around?

To be clear/transparent my experience has been playing core cod. I haven't gotten to warzone as of yet.  
However, in order to reverse boost you need a few essentials:
2 separate accounts from 2 different platforms. 
Another copy of the game (using a secondary account isn't as useful/accurate/consistent).  Don't use the same/similar name.
Make your second account a bot account with a k/d of 1.1 k/d or lower in Dom/TDM/Patrol/Kill Confirmed/Etc. This can take a few hours. You want 1 kill with every 10 or so deaths per match.  You only have to do this 1-2 times per game mode.  Now you can bypass this and have 0.00 k/d (you don't bother to create a bot account).  This makes your bot account very limited in weapon selection.  I've also found by doing this defaults you to booth RB and regular lobbies. 
Setup your netduma OS traffic prioritization accordingly.  Make sure UpNp is enabled. And it shows the port of both gaming platforms.  Make sure your platform is properly labeled in Device Manager. Setup your congestion control if you have other devices connected to your router.  If it's just your 2 gaming devices I suggest you disable QOS.
Friend your bot account. Search for lobbies with your bot account. Session join your main account to your bot account when your bot account found a lobby that is not full. Then back out your bot account from the lobby.
There are a few videos out there that explain it better though on youtube. Just look up "reverse boosting Vanguard" "reverse boosting Cold War".  What they don't tell you is that those easier lobbies don't last forever.
The 1st few reversed boost matches might be easier then normal.  However, as you progress in later RB matches opponents get "smarter" and matches will tighten up on you if you are not careful.  This is normal behavior as SBMM is kicking in as it should.  You simply don't get EOMM'd.
But when you beam a person for the first time will be intoxicating.  It's like you are playing another game.  All your bullets are connecting.  You try another weapon and realize that the RPM is too slow.  So you setup another weapon with a high rate of fire and beam another.  Then you notice that you are moving faster then before.  You blink your eyes more and 🤔.  Nope, you confirmed that for whatever reason you are now moving faster then you ever did before.  You get all getty and a smile will form on your face uncontrollably 😂🤣.  As you melee players for the 1st time 😲.  You play the entire match and regardless if you win/lose your thoughts can't help but wonder if this is what you've been missing all this time?  And with a sigh you realize you've have.  😡
 

0.2 is working very good and it is also logic. You need a little bit of knowledge about netcode in games to understand why. Here is a good starter guide: https://forum.netduma.com/topic/16499-networking-lag-compensation-and-hit-detection/

You seem to just get it. Nothing will magically make you a god at the game. Idk if all the sweats are in league play now, or if they toned down the sbmm, but I no longer feel like after a few good games I can no longer compete. I may just be getting better at the game, and those lobbies that were brutal before, just aren’t as bad. Naturally you’d get better at a game having played for 3-4 hours a day. My map awareness and general understanding of how the game flows has helped me get 5-6 less deaths a match and 5-6 more kills. So maybe that’s it. I still run into the unkillable person per lobby, but at this point that’s just par for the course. When traffic prio was working my hit reg was great and consistent. That’s the biggest problem I face now. Consistency. I get absolutely melted and try the same gun, same attachments, and it’s like I’m shooting marshmallows. The point blank kills are maddening because for me on pc, the closer I am to an enemy, the less my bullets register. 🤦🏽‍♂️  I can’t try fun creative gun variants. Task force barrel is a must, yet I get pooped on by ppl using attachments I can’t even think about using. Lol. Turning off cross play helps with the aim assist snapping deaths and getting locked on through walls, but it takes FOREVER to find a match, and the try hards use controllers on pc. Can we get input based matchmaking pls? Sigh. The cod struggle is real. 

Ok ladies and gentlemen idk if they fixed the hit detection issue on pc, but my hit detection has been absolutely brilliant like “back in the day” when I first tried port prio. I’ve changed absolutely nothing on my end and I’ve played at least 20 games across servers from Texas to Cali, to Oklahoma with consistent results across all. I haven’t had to deny a server all evening. Kinda makes me want to remove all my denies and start over. For reference my congestion control sliders are set at 98% up and down with never selected. My bandwidth allocation flower has all values equal. Share excess is not checked for up or down. NO traffic prio. I’m forwarding the ports activision lists. Upnp is on. Weird I know but works best for my setup. 🤷🏽‍♂️ DumaOS classified games is on. Geo filter is set to about 500 miles around where I personally live. I think that about covers it. It’s so good right now I hope I don’t have to reboot my router and I hope there’s no update to the game. 🤣 I’m working on lmg’s right now and the M60 is making ppl quit the lobby. I hope y'all have as much luck as I’ve had because this came out of nowhere. 😳
