I have both Parallels and Fusion. I personally do not like Parallel becuase I have a hard time un-installing it. As of today, there is no way to clean up all the Paralell configuration without reinstalling the MacOS. I contacted their support, and they are awesome. But they couldn't resolve it.
I roll back to Fusion. I believe Fusion support a slightly higher version of Diriectx and Fusion 3 is coming next week.
