Apple held a schedule during WWDC 2023, directly mentioned how to simulate running Win10, Win11 system games on macOS, and listed the “command and Direct3D conversion type” and other key details.
In this event, Apple introduced Metal Shader Converter and Metal debugging tools by building a new environment on the macOS platform to further exploit the potential performance of games and reduce the amount of upfront work that can take months.
After digging deeper and examining the source code, developer Andrew Tsai basically confirmed that the emulation tool is actually a modified version of Wine based on CrossOver 21.1.1.
Tsai also demonstrated the emulation of a Windows game running on macOS, supposedly under Rosetta 2, and was able to render the game using DirectX 12.
Prior to the opening of the WWDC 2023 developer conference, development company CodeWeavers announced that CrossOver will support Microsoft DirectX 12 this summer, which is good news for gamers.
CrossOver is a Windows emulator for macOS, Linux and ChromeOS, based on Wine, that allows these systems to run Windows applications natively.
