Computer slowdown after launching Haven

Postby Boleval » Sun Dec 28, 2025 9:01 pm

Hello,
for some time now (since the launch of world 16.1), I've been having a problem that occurs on both the regular client and alternative client (Ender).
When playing Haven my computer slows down significantly—I can't do practically anything and have to restart it to get it working normally again.
- Sometimes it starts doing this after a few minutes, sometimes after a few hours, sometimes the problem doesn't occur at all.
- I used Ender throughout the entire World 16 and never had this problem.
- I tested the standard client because I thought it was a problem with Ender, but the slowdowns also occurred.
- The task manager does not show any load on the memory, processor, or disk.
- Stopping the Havenen process does not help - I have to reset the computer for it to start working normally.
- I tried removing Java and Haven files and reinstalling everything, but the problem still occurs.
- Recently, the problem has gotten worse. Today, I had to reset my computer practically every few minutes.
- I haven't changed any computer components or the operating system recently.

Does anyone have any idea what might be causing the problem and how to fix it?

Just a guess in the blue. Since you didn't specify any of your system specs.

Have the resource monitor open, and check your disk usage / latency.
If you truly don't see ram / CPU usage (clocks okay?) it might be the end of life of your hard disk.

My first question would be: have you tried if this happens with other games or software?

Haven is not a performance intensive program. Also if it was haven's fault, ending its process should bring everything back to normal.
The fact that things go back to normal after a restart, might indicate a RAM issue.

The problem only occurs with Haven.
Other games/programs have never caused this behavior on my computer.

I would also opt for ram issue
Java VM claims RAM in advance (xmx, xms attributes)

I checked my computer today with a diagnostic tool for testing RAM and no problems were found.

Furthermore, I think that if the problem was faulty RAM, other programs/games would also cause the computer to slow down.

i had brutal slowdowns then freezes on mu Linux while doing sht then I realized I didn't have tons of RAM and didn't create a Swap partition... on Linux GParted fixed everything quick then restarted, on Windows I have no idea, but the first guess is RAM is just enough to start stuff, then it freezes up when its full? i dont remember windows having swap partitions, maybe it just freezes

We need more information about your system.

Also, have you tried running it through steam? (or if you do already, have you tried the stand-alone client?)

is your bonzibuddy forcing itself to the front so haven is constantly running in 5FPS background mode?
