I have the same problem. After starting the game (skins are loading + automatic login), there is a severe lag. Afterwards, my FPS drops from 144 to a constant 72, even after I load into a world or realm.
If I am playing in a world or on a realm and enter an area where performance drops significantly (for example, a complex storage system), and my FPS drops under 70, the game sets a new FPS limit of 30 FPS. The new FPS limit is capped and remains unchanged even after leaving the mentioned area. The only fix is restarting the game, where the whole problems starts again.
