My minecraft performance degrades the longer I play. The game will start to freeze for a fraction of a second before it continues. While this starts to happen every 10 minutes, the longer I play and the more I explore, the worse it gets, until eventually it happens every second.
Looking at my task manager, there are no shortage of resources. I am running of an SSD, 32GB Ram, I have a fast graphics card (AMD Radeon R9 290X), nothing runs in the background etc. Restarting minecraft solves the problem immediately. I limited the game to 30FPS and it pretty much stays there.
It's the latest version of Oracle Java (161), 64bit.
Any idea how to solve this issue?
