I have a brand new Macbook Pro 13" (2010) with 4 GB RAM / Nvidia chip, the video performance when running Solidworks in Windows XP using Parallels 4 (3848) is very slow. My old Macbook 13" (2007 model) with 2 GB RAM using integrated Intel Video runs the exactly same Virtual Machine much faster! Old Macbook 13 is running Mac OSX Tiger, new one is of course Snow Leopard. Any suggestions?
