A Windows 10 64-bit or Windows 11 64-bit license is required, and this operating system must be installed either in BootCamp or in Parallels (the virtualizer enables Windows to run within MacOS). When running via BootCamp, performance will be virtually identical to using the software on a “PC” system with the same hardware specification as the Mac.
When running via Parallels, if the system features a discrete graphics processing unit (GPU) as opposed to an integrated graphics processor (IGP), performance and visuals will be lower and of lower quality than when using BootCamp on the same system. There are two reasons for this: (1) Parallels is running “inside” MacOS and therefore Windows does not have access to all of the system’s hardware resources such as processor cores and memory; (2) Parallels does not support the all the OpenGL features that Wysiwyg/Vivien requires, despite it supporting the necessary OpenGL version. (For more information about OpenGL versions and features see Visualization Requirements.) The difference between using BootCamp and Parallels is less noticeable when the system does not feature a GPU (and uses an IGP instead).
* IMPORTANT: Wysiwyg and Vivien are unable to run on ARM-based (“M1”) Mac systems at this time, as a result of dongle drivers not being available from our dongle manufacturer. Options and alternatives are being investigated, and updates will be posted on the Forum thread we have dedicated to this matter. Once a conclusion has been reached, this information will be updated.
