Thanks for the response Shepard, we be but your humble flock of sheep looking for guidance to return to gaming with the bros
I've managed to generate the DxDiag as I just learned what and how. Not sure what I'm looking at although I see 1 through 9 WER sections at the bottom, hopefully that is helpful to you and the rest of the Operation Broken Matches Strike Team (feel free to use that). I generated DxDiag1 earlier today before deleting folders, repairing game, and flushing DNS, set my VPN's custom DNS to cloudfare, and DxDiag2 is just now after doing those things. I attached both in case there are any discrepancies that might be informative.
The pattern is still the same, that being: a 1-2 game match-and-load-in maximum before having to restart the game, regardless of which mode, and only Conquest and TDM work on my own. When successfully loaded into Conquest, only six of the 128 maps (Breakaway, Orbital, Manifest, Spearhead, Flashpoint, Exposure) are possible to match-and-load-in; TDM will match-and-load-in 1-2 games regardless of map; Breakthrough has yet to load into any games after matching, not even empty lobbies. Then I have to just restart the game, maybe do App Recovery in the EA App, rinse and repeat.
Furthermore, I cannot join Conq64 games at all, even through joining a friend, which does work for the few 128 maps I mentioned. When I click the Join Game option for the 64 games, nothing happens at all, not even an attempted load-in. (Sidenote, when I match on my own into El Alamein or Battle of the Bulge Conq64, the music for those maps loads in, and continues to play even after being booted back to the lobby, until another successful load-in happens, I don't know if that makes any difference.)
I was however able to join a Breakthrough match through a friend via the Join Game option, and it subsequently matched and loaded in two more times after that round. When I joined, my ping indicated my local US East server, then the next match, the ping went up to seemingly US West level (from ~10ms to ~70ms) and then back down to US East for the third match. Then it stopped loading in again.
Also, when I'm in a party with my friend on PS5 as the leader, they've managed to match us into both Breakthrough and Conq64 for 1-2 games and I load into them fine before it stops working for everybody after those few times. I just cannot on my own match-and-load-into either one of those, or any of the other 128 maps, etc.
As you can probably tell from my laptop specs, I can't really play 128 games without it being a time-travel experience, which is why generally I only play Breakthrough or the Conq64 games. So playing these few games that I can load into, well let's just say I've gotten really good at spotting. Anyways, hope this info is useful, looking forward to you and the Taskforce solving this crisis, thanks again
