Agreed on the native 64 bit support. When it's all about big math! Windows supports multi-core but hyperthreading seems to be a redundant feature with VW2009 - the "cores" remain parked and lifeless. Rendering - Why is it so slow? My AutoCAD friends seem to have a much smoother and quicker journey through equivalent 3D objects while experiencing good quality render, using machines with way less grunt and RAM.
