Quote - Hello,

I tried DS3A some time ago and found that despite they call it "professional", it does not even support all my CPU cores for rendering.

DS, all versions, uses all cores on single CPU machine and I'm near certain it uses all cores on dual CPU machines. Some processes, such as Shadow Map rendering, were not multi-core but as far as I recall that was already fixed by the time DS3A was released. If you sent a scene to an external version of 3Delight you would have been limited by that, but teh limitations on the internal version are in the form or unsupported features compared to the full version.
