Yup, sounds about right. Same issue with I tried Fusion a few years back...

I use RhinoCAD / MadCAM, and it is really the only thing keeping me on Windows. I've heard it works on some emulators like WINE, but haven't yet made the effort to test it, and can't really afford to have any latent issues pop up at random times after initial testing seems to work, so still enduring the Microslop insanity... ugh
