Posting old research quotes from the pre-Battlefield 3 era and using it for today’s narrative is disinformation at best. Since that pre-Battlefield 3 time period (where your quote was pulled from) we’ve had countless upgrades to hardware, internet speed, and code optimization. What was valid then isn’t still valid today.
The current problem with the Battlefield 2042 128 player gameplay is:
Map design,
Too few objectives for 128 players,
Not enough infantry cover,
No incentive for players to disperse across the map to hold/capture/fight multiple zones at the same time.
What applies to 64 player gameplay needs to be doubled for 128 players (not just map area).
Think of it like “ten pounds of manure in a five pound bag”, the excess needs a place to go and just leaving it out in the open without cover will stink everything up.
