Hello. I am using Parallels Desktop 8 on 2013 MBA Core i7 8gb RAM 512 SSD. I need to work in CAD/3D programs through PD8(BootCamp is no way!). When I work in Windows 7 I need maximum PD8 performance, don't care about OS X performance in that time. So what should I optimize in PD8 settings? How much RAM to give, how much cores and how much video memory? As I said before when Parallels is running nothing done on OS X(maximum is Mail check for 1 minute). Is it ok to give 4 cores, 4Gb RAM and 1Gb video? Or this is not as good? Thanks for answers and sorry for my english )
