Oh hey another "I'd fully be on Linux if it wasn't for Fusion 360" person. Although in my case I'm too lazy to maintain VMs, so I just use windows as my base OS. Microsoft may force the issue next year when my perfectly good desktop stops getting Windows 10 updates and can't install Windows 11.
I have no GFX performance with virtualbox. Sometimes I run Fusion via another system and remote connected using NoMachine which works better even with the USB spacemouse connected via NoMachine...
What's torturous about using Fusion 360 in a VM?
