It looks like you have a decent connection (11ms ping, 46Mbps down, 10 Mbps up, low latency to US servers, and a consistent ping).
Reducing the game to the lowest graphical settings shouldn’t really affect the latency. (In the past the game didn’t handle low fps connections terribly well but we re-implemented much of the networking to resolve this.)
In which case - it looks like the latest update has introduced an issue that has caused this. Clearly there is something in the client that is causing these large stalls.
There is nothing obvious in the client logs (or server logs) that would suggest there is a problem.
This is almost definitely a different issue - either your connection was down or something else. I would hope that if you rerun the game these issues would not reoccur.
Assuming that the original issue is in the client then we’ll only be able to investigate this once the dev team is back in the office in the new year. I appreciate this isn’t really helpful for you at the moment - but hopefully you can be patient.
I’m sure the team will have some more questions for you and may ask you to try some custom builds that include more logging.
