I use Rhino V6 (WIP) on Parallels with the latest MacBook Pro (AMD GPU). Other than in my regular V5 Windows suite (which I also use with Parallels, on the same machine) switching between Viewports (Perspective, Top etc.) is extremely delayed i.e. nearly impossible to work with. Happens when I double- or single-click the viewport tabs and click on the tabs at the bottom likewise.
Thanks for considering
