Running SW13 on Parallels with MacBook Pro Retina???? OpenGL

Hi, I have been to the end of Google and back trying to find the magic valve needed to enable Hardware OpenGL for Solidworks 2013 running on Parallels 7 with Windows 7 64 bit. Unfortunately I have the very annoying Enable software OpenGL greyed out and hard set. Needless the say, SW graphics runs very slow.

Has anyone here gotten around this problem using a new MacBook Pro Retina display? Thanks
