Hello, I've been playing on DE - 1239 for a number of weeks now, and it has consistently had terrible performance at various hours of the day. It tends to have a few hours where it'll be okay, usually during working hours. But the performance is extremely inconsistent outside of that small window, and especially during peak times (6-9PM GMT) it will be borderline unplayable. Driving a vehicle is a death sentence in moments like that, which makes the server feel very frustrating to play on.
I held off on making a bug report as I assumed it would be related to the Frostline release with player counts surging. But this has now been a problem for multiple weeks with zero sign of improvement.
The performance is definitely server related, and not my local machine, because my friends and I play at the same time, and they all get the same issues. The server performance icon will be red in the corner of the screen for a long time. People will be lagging as they move. Doors take seconds to open. Cars jump all over the place. And most annoying of all is that the server will frequently kick a huge number of players and everybody has to rejoin, which can get people killed in-game as their characters stop dead in their tracks for 15 seconds after they're kicked.
