If you made the mistake of upgrading your virtual copy of Windows under Mac OS X using VMware Fusion (version 8 here), you may find Windows 10 runs painfully sluggish. The answer? Disable 3D graphics acceleration.
- Shut down the virtual machine.
- Bring up the virtual machine settings (⌘E).
- Select “Display”:
- Deselect (remove the checkbox for) “Accelerate 3D Graphics”:
- Close out the settings, and restart the virtual machine.
If you’re like me, you’ll find it far, far more usable.
UPDATE:
Having purchased a more modern i7 based Mac I can thankfully say this is no longer necessary.
