[Bf-committers] Thoughts on speeding up...

Well, the problem is that Blender is currently a mainly single-threaded
application. Many of us have robust, dual CPU machines with support for
simultaneous multithreading. What should be possible is that Blender
computes the scene in the background, and as you edit the scene, it 'builds'
upon this current computation.

It is an interesting idea, and the same idea I had a few days ago and
already proposed to Ton. It can be done, but it's some work.

BTW, I would have used it for also always providing a better preview
of the scene in the 3d views (an extension of shaded view).
