Re: SH3D Memory Usage
OK! Thanks! So I'm guessing I shouldn't try to adjust the memory limit as described in the FAQ. Just leave it as is.

I've not run into any problems yet. I was just curious.


Setting a 32bit JVM to 1GB is pretty reasonable. Plus a 32bit JVM is more frugal with memory because all reference pointers are smaller. If the operating system cannot supply sufficient contiguous RAM, the JVM will terminate on start-up. Even at less than 1GB the JVM may still sometimes fail to start because of what else is running and how memory has been allocated by Windows (but I would only expect this if you were running lots of memory hungry stuff).

If the max is too low for size of your model, the JVM will probably become jerky or sluggish as it starts to devote more and more CPU time to garbage-collecting (looking for and recycling anything that has been freed up). If that were to occur you could try pushing towards 1.5GB.
