The MacBook Air video card is very limited to run HD movies, and when you run Parallels accessing a Vm, the video performance is very poor. I would like to know if installing Windows through BootCamp, could increase this performance. 1 - Any one knows if there's some advantage on installing Windows through BootCamp instead of Vm? Note: One desvantage is that TimeMachine can not auto backup BootCamp partition, but it "yes" do backups the Vm. Thank you very much in advance!
