I made #Live2D Cubism Editor run faster on M1 macOS
github.com/Birch-san/arm-…
faster at loading models
reduced idle CPU usage Image
the UI lag is caused by libjpen (the tablet driver). deleting libjpen-2-3.jnilib makes it run way faster.
I also upgraded it from Java 8 to Java 17, added Graal JIT, and switched the renderer from OpenGL to Metal.
there are a few breaking changes in JDK17. I reintroduced sun.reflect.Reflection using `--patch-module`, and wrote a `javaagent` to locate Apple eawt classes.
I upgraded jogl and gluegen — M1-native support only became available in a recent release candidate. I speculate that this has been the biggest reason preventing official support for M1 in Cubism Editor. no blockers now!
