Virtualize 3D video hardware for macOS clients

With release of macOS Catalina, and its removal of 32-bit application support, a number of users are looking for ways to play their 32-bit, 3D games on their Macs. One solution would be to run Mojave or High Sierra in a Parallels VM, but unfortunately, Parallels does not appear to virtualize 3D hardware and support Metal like it does with Windows and DirectX.

Can this support be added to Parallels for macOS clients running in VMs?
