Parallels Desktop 15
First, Parallels Desktop 15 adds support for Apple’s Metal API. This lets the company also support DirectX 11, moving away from OpenGL. The company says you’ll be able to run intensive programs like CAD/CAM software, and games like Crysis 3, Space Engineers, and more.
The software also supports features in macOS Catalina, like Sidecar, support for Apple Pencil, and Sign In with Apple. Catalina also drops support for 32-bit apps, but you can run those in Parallels Desktop 15 as long as you load a pre-Catalina OS.
