Official servers lag even with perfect internet

I decided to figure out why Battlefield 6 (2042) lags on official servers, even though everything is perfect on community servers. I have a cable connection, stable ping (11-15 ms), no packet loss, high FPS—but on official servers, there's constant desync, rubber banding, and hits aren't registered.

I took several screenshots with network graphs enabled and analyzed everything in detail.
Here's what you can see:

LAT / ALAT: 11-15 ms — excellent connection.

PL IN / PL OUT: 0% — no packet loss at all.

BW IN / OUT: stable, no drops.

SFT / CFT: noticeable spikes — 13-26 ms.

TN (Total Network): reaches 800+ ms.

So, my latency to the server is minimal, the internet is clear, but TN and SFT/CFT are rising sharply. This indicates that the problem isn't with the client, but with the servers—they simply can't handle the load.

This isn't the case on community servers: everything is smooth, every shot is registered, and TN and CFT remain stable.

I've already tried everything suggested online—user.cfg settings, disabling crossplay, changing DNS, updating drivers, Windows, and BIOS—but nothing has helped.

As soon as I connect to the official server, I experience the same lag, desync, and strange delays when shooting.

It seems the problem is with how EA's official servers operate: overload, low tickrate, or something at the backend level.
If anyone has noticed this, please share your graphs and observations. I'd like to understand how widespread this is and whether EA has any reaction to it at all.
