ok this version is too much good. It will be distributed to nebula server owners only, because they could pissed off because they paid for something wich now works very well also in normal nebula (for example people bought server even using a x64 daw). And Mac osx users: they paid for server and localserver is not too much optimized, this new version outperforms it without the server component (especially if they are not running snow leopard) So the optimization will be adopted only in nebula server release until we improve the server adding some other new exciting features.
So Nebula3 Server will be based on a different engine we'll name Core3.
nebula2, nebula3 -> CoreI (no optimizations) nebula3 pro -> CoreII (cached vectorial engine) nebula3 server -> Core3 (cached vectorial engine, shared memory)
