Hi, I use Parallel on my MacBook Pro M1 (16GB) with Windows 11 Insider, but everything is very very slow since 1 month, especially with x64 applications. I use only 2 x64 applications, sometimes can take 15 minutes to open an x64 application ! Win CPU always at 100% when MacOS CPU is at 15/30%.
Win11 high usage is many time : System, Explorer...
The build is Win11 Pro Insider Preview 22543 / 220122-2315.
Parallel settings are CPU/RAM : Auto, Graphics : Scaled.
Did you encounter same problem?
Go to System Preferences > Spotlight > Privacy and press the + sign and add the folder where your VMs are stored.
This helped a lot for me.
