Recently I have situations when my performance drops down to exactly 1 frame per second, no idea why.

When reconnected, the 1 FPS continues and I lose connection to the server. 2nd reconnect fixes the problem.

Normally playing with 30-40 FPS, happened outside of small villages (inside Kabanino and north of Vishnoe).

Most probably not connected to player actions in my proximity.
