Minecraft Java running slowly on Raspberry OS 64bit on RPi 4B 2GB (fan cooled) about pi-apps HOT 10 CLOSED

Actually, the install script is just all the commands from https://www.raspberrypi.org/forums/viewtopic.php?f=78&t=284448 smashed together. I think that you can change the xmx and xms stuff in the JVM Arguments textbox when you click "Edit Profile" in the launcher.

from pi-apps.

thank you. I tried that but I had another error.
I updated pi-apps today and now Minecraft won't start at all.

Umm. I think you forgot some JVM args. You seem to only have -Dorg.lwjgl.librarypath=/home/pi/lwjgl3arm64 -Xmx1G -Xmn128M whereas it normally has -Dorg.lwjgl.librarypath=/home/pi/lwjgl3arm32 -Xmx1G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

my bad, I misread the instruction to add and the beginning of the arguments and not replace

I suggest you go ask at https://www.raspberrypi.org/forums/viewtopic.php?f=78&t=284448.

I'll do it, thanks for the help :)

Has it worked yet? If it has then please close this issue.

nope, I posted on the link you sent earlier.
I guess I'll close the issue since it's not related to pi-apps.
Thanks again!
