Parallels Desktop 16 and Windows 10. Windows is extremely slow with 100% processor load

Sorry guys.
I have to back paddle: Change to 1 CPU does not help - system is still extremely slow, practically unusable.

 

Same issue for me. Horrible performance on any configuration except 1 CPU and 4G.

This seems to me to be a pretty big "miss" by the Parallels team.

Thanks for posting, Michael. You're my Hero of the Day

 

I want my money back. Parallels 17 running Windows 10 is a joke. It's completely horrible. SLOW SLOW SLOW SLOW SLOW SLOW

 

Hi,
I had the same problem and the Parallels hypervisor is just so bad with VMs.
Go To ==> Materials ==> CPU and Memory ==> Click Advanced ==> Change the hypervisor to Apple.
You should be ok
Cheers

 

Wow, I've been frustrated living with crappy parallels performance for some time. After reading this thread, I changed to the Apple Hypervisor and wow, what a difference! Parallels is now usable again! Thank you.

 

Same here. Windows 10 is practically unusable. Allowed only 1 CPU and now better but still slow. Please fix this already.

 

Did you switch to the Apple hypervisor? In my case, that made a huge difference.

 

Yep. Apple hypervisor runs like a charm with Windows all versions.

 

maybe the OpenCore patch with unsupported Macs make slow down the VM, even 1gb but not enough.
