The user interface itself (menus, tools, dialogs, and the like) hold up well with retina resolution enabled. It is only the drawing area that suffers. If I'm reading the QCAD documentation correctly, it uses QT5 for the interface and the canvas. And QT5 uses OpenGL. Apple has depreciated the use of OpenGL in favor of Metal and Macs are "stuck" at version 4.1 of OpenGL.andrew wrote: ↑Mon Feb 24, 2020 1:31 pmUnfortunately, we have to rely on underlying toolkits for the rendering. If you're not happy with the performance or rendering quality of QCAD, I'm happy to offer you a full refund.BobRockefeller wrote: ↑Mon Feb 24, 2020 1:22 pmAre there plans to upgrade the underlying rendering engine to solve this? More and more computers, and almost all Macs, have high-resolution displays and those computers are especially prevalent in CADD.
Do I understand that correctly?
If so, does that satisfactorily explain the poor retina drawing performance?
With the deprecation of OpenGL on Macs, the future of CAD on Mac will have to be Metal. Are there plans to find a way to migrate QCAD?
