[SOLVED] Horrible Performance in Minecraft Java (64-Bit)

[ethan206]

I have really bad stuttering problems and crashes when running Minecraft Forge 1.8.9. When I run Minecraft 1.17 or when I go on Lunar Client 1.8.9 I don't encounter any of these issues. I suspect it's something to do with the version of Java (JVM/executable) it's using though I'm not entirely too sure. I remember when I used 32-bit Java it was running way better than 64-bit and when I press F3 it shows I'm using Java 1.8 64-Bit. I uninstalled every 64-bit version of Java on my computer (Update 311?) using the Java remove tool yet somehow Minecraft is still finding a way to use 64-bit Java. I also know you can select which Java executable to use in the Launcher and was wondering if I could use the one Lunar Client uses (Zulu Platform x64 Arch. etc.) as I heard it's a much more updated version of Java.

It’s probably using it’s own Java

They may have packaged it with the product
