Ok we've spent the whole august debugging mac osx. It was an hard task. We are going to introduce next release of the engine named core4
This will be the pattern:
nebula2 -> CoreI (the same as before) nebula3 -> CoreI (the same as before) nebula3 pro -> Core4L (Core4 Light, which is an evolution of CoreII) nebula3 client/server -> Core4 (an evolution Core3, it features a better RAM optimization and resource sharing than Core4L).
New engine is optimized on new CPU architectures and a better multithreading. Core
core4 working well on win7x64, i7 quad 2.13, 32 bit neb server on reaper 32 maybe 1% less cpu on each neb instance, system way more stable running at 256 sample latency no more crackles? - was good for 5 hrs+ last test. before i got crackles/distortion after 90 minutes
