How to make Minecraft Java Edition use the dGPU

[tylrwong]

I've figured out that setting the Java Runtime Alpha binaries (located at C:\Program Files (x86)\Minecraft Launcher\runtime\java-runtime-alpha\windows-x64\java-runtime-alpha\bin) to High Performance will force it to run on the dGPU, at least for native 1.17.1. I'm not sure which runtimes are used by which versions though, so it's probably a good idea to set both the 'alpha' runtime and 'legacy' runtimes to High Performance, specifically the java.exe, and javaw.exe in both directories.
