You would get a fully separate leisure desktop if you were running Linux in that VM so it sounds like you are running Windows in the VM because Linux gaming is not adequate.
I'm not the person you replied to, but I'm in a situation where I want GPU passthrough to Linux guests. The problem is that the Looking Glass guest application for linux is unmaintained. This makes it impossible to have the same setup but with a linux guest instead of Windows.
If you want to have GPU accelerated video output from a guest vm to a linux host, the only way is with a Windows guest (to the best of my knowledge). If you just need compute then that is different.
