I've just purchased a brand new copy of Parallels Desktop for by brand new MacBook Pro. I'm now trying to enable directX in the video tab of the configuration editor, in order that I can try and run a computer game in my virtual Windows XP operating system. I've read the pdf "Parallels Desktop for Mac User Guide" and see that I should just have a tickbox that reads: "Enable DirectX" but it just doesn't exist on my configuration editor! Help!!
