I have the following MacBook Pro configuration:

  • 2019 MacBook Pro 16" running macOS Big Sur
  • 2.3 Ghz 8 Core Intel Core i9
  • 32 GB 2667 DDR4 RAM
  • AMD Radeon Pro 5500M 4GB and Intel UHD Graphics 630 1536 MB
  • 3 external monitors:
    • 1x DP via CalDigit TS3 Plus Dock
    • 2x HDMI via USB C to HDMI cable

For reasons out of my control I cannot install Windows 10 using Boot Camp so I am running Windows 10 in a Parallels VM.

I am not doing anything or running anything else in macOS. I turn the machine on, log in to macOS, and then start the the Windows 10 VM in full screen and all monitors.

Since I am exclusively using the Windows 10 VM I want to make it as fast/smooth as possible. So far I configured my VM like so:

  • 2 processors
  • 24576 MB RAM (24 GB)
  • Adaptive Hypervisor checked
  • 512 MB Graphics
  • Resolution = Best for external displays

Is there anything else I can set/configure/do with my macOS host machine or the VM to make my Windows 10 VM experience better?

  • Are you dissatisfied with the performance of this setup? I'm by no means competent to to speak about Windows VMs, but from my limited knowledge, the apps which are being run on the VM framework, and the resources they consume, need to be considered in any design. Are you doing 3D animation rendering or Outlook and Adobe Suite?

  • No. I just have a bunch of proprietary office tools that can only run on Windows. I can't get a new machine, they won't let me install Windows directly on it -- so I am stuck with a VM. :/ Sep 13 at 3:28

    Perhaps you should explain what you mean by "they won't let me install Windows directly on it ", Sep 13 at 3:39
  • @DavidAnderson That isn't really the scope of my question. I have a MBP with a Windows 10 VM in Parallels. I'm just wondering what I can do, settings/configuration wise, to make sure the VM is as fast as possible. Sep 13 at 19:02
  • I would seem to me that if you Mac has 8 cores, the I would give Windows more than 2 processors. Sep 13 at 23:33
