Official Server #1301 - Bugs, Lugs, Frizzes

Hi all! Please help me with this problem. I’ve been playing on server #1301 for over 500 hours. Until recently, there were no complaints from my side about the server, everything was played smoothly, but the last week is just disgusting to play. Especially in battle - enemies constantly move inadequately and it is impossible to catch them, when running (on a horse or on foot) the endurance scale does not go away, and then sharply goes into minus. It is the same with other elements of the game - the inventory opens with a noticeable delay, as well as eating food and drinking water, that is, you drink water, and the scale will rise in 3-4 seconds.

The most interesting thing is that I did not change my provider, did not change the computer configuration, that is, everything remained as before. In the game, ping through (togglehud) shows an average of 90-100, and the server fps is 15-20. But the lags are still present.

What can you advise?
