"may outperform native macOS builds of titles due to DirectX support"
Okay, I think it is time that Borkzilla swallows the pill and licenses its DirectX technology to all and sundry. DirectX is clearly the best tech for rendering games, and Redmond has profited from it enough now. Windows is a service, right ? So license it off to Cupertino and the world of Linux and stop vainly and uselessly trying to get everyone to Windows.
Everyone is already using Windows apparently - even the well-heeled shiny ones who take care to show to everyone that they have a Mac. Apparently, they still boot into Windows, the irony.
I won't suggest open-sourcing DirectX, I know that that will never happen, ever. So just sell the license already.
