OutofMemoryError when loading some worlds #13

Closed JamesMonkey closed 7 months ago

JamesMonkey commented 7 months ago

When loading a world in MiEx v1.2.1, most of the chunks load perfectly. However, the program seems to hang on some chunks that render black, resulting in a log error. Below are two different logs for two different worlds that seem to share similar out-of-memory errors.

I have just released a new version which more aggressively unloads chunks in order to reduce peak memory usage. I'd also recommend to make sure that you can running MiEx using a 64 bit version of Java and not a 32 bit version of Java.

Please let me know if this new version improves things!

..I can't believe I had 32 bit java installed. The latest update combined with Java 64 bit resolved this issue. Thank ya sir!
