Setup: I've been running Parallels Pro for over a year on a fully loaded Mac Studio with M1 Ultra. Optimization is set to 'no limit'. I've tried 'Automatic' for CPU & Memory and I've been running 8 CPUs and 20GB allocation more recently. Windows settings are also set to high performance. Issues: 1. Parallels performance has been disappointing running Siemens NX (CAD software) on Windows 11. Same software with same 3D parts runs a lot better on a sub $2000 Dell. 2. Graphics look weird in NX. Lines look jagged like there's no aliasing. 3. Occasionally, Parallels freezes completely when trying to pull up a folder or transfer a file from Mac to Windows desktop. I'm curious if there are any optimizations I'm missing. I'm just about ready to look for a different solution. Any feedback is appreciated.
