How does VW use the processors in a Mac Pro

[Assembly]

I put this post in the general area too, but no one wants to answer. As the VW Guru are usually looking at this area of the Fourm I post here too.

I run Vectorworks 2009 on a 2 x 2.8 Quad Core Intel Xeon Machine.

I am using a view port to do a radiosity rendering. Lots of crashing so I keep stripping back objects.

I check my the OS X activity monitor and find only one of the processors is being used.

Does anyone know how VW accesses the processors?. Can it use multiple processors at a time?.

if it does how do i make sure my comp is running optimally?

if not...WHY NOT???!!!!

Im not 100% sure how VW works with Viewports. But if you render on a DL you can actual see the horizontal lines of each Processor working. I have a dual quad core at home and I see eight lines when I render. I know that rendering on a DL is faster than rendering on a sheet layer VP.

VW only uses one processor except for rendering where it uses all available.

Multi-threading (using multiple processors) for them main program is an ongoing wish list item, but it's not going to happen soon, to the best of my knowledge. To make it happen will require a rewrite of just about ... everything.
