I'm trying to run Minecraft Java Edition on Aarch64 Windows device.

My device is Surface Pro X. Since this guy's CPU(ARM) doesn't support any x86 features, it has to emeulate the x86 features. So huge performance drop occurs. It's fine with simple programs like Chrome or MS Office, but if you try to run something a little bit heavier, like Minecraft, it becomes SSSSLLLLLLOOOOOOWWWWWW as hell.

Since Minecraft JE is a Java program, I thought that I can somehow manage to run Minecraft but bypassing the x86 emulation, using the Aarch64 ported version of Java Runtime, JVM or whatever.

So I installed OpenJDK 16.0.2 Aarch64 Windows version (that was the only ARM Java I could find) and told Minecraft launcher to use the OpenJDK's javaw.exe.(of course, the one inside the bin folder) But it didn't work.

Release 1.17~ would just crash and leave 'Exit code 0', and Release 1.16.5 would leave a Crash Report, like down below.

Yeah, it's complaining about not having lwjgl.dll file i guess...? but I have no idea what should I do in order to deal with this thing.

I left a crash report file from 1.16.5. Hopefully that helps us something...

Thanks.

== Update ==
When this error happens, I found that 'OpenJDK platfrom binary' uses virtually 90% of my CPU. Still got no idea what it could mean.

I could also get a log from 1.17.1 version when it crashes. I used "-Dorg.lwjgl.util.Debug=true" parameter in order to let the game display some more information what could be wrong. I uploaded "from1171.log" file, hopefully this can help solving this problem.
