Missing video / graphics options for Configuration in Parallels 13 for macOS

In this old posting a problem was explained regarding graphical anomalies in the application. The poster was told by Parallels support to go to VM Configuration > Hardware > Video > Change to DirectX9 and disable Vertical synchronization.

This was supposed to be for a macOS guest machine and so the DirectX9 part did not make sense, but even still, none of these configuration options are available now for Parallels 13 macOS guests. There is a "Graphics" configuration item and within that ONLY Memory is settable. Is there some other way to enable Vertical Sync or some other setting(s) necessary to resolve this graphical problem?

 

So nothing here Parallels???

 

Still nothing here guys? It would be really helpful to get some additional help on this, especially when you've been giving out false or misleading support info before.

 

Hello viola.
