I am virtualizing Windows 10 Pro on a MacBook Pro. When running a game, CPU usage shoots up to 100% (or more) as verified by the Windows Task Manager and the macOS Activity Monitor. CPU usage drops to next-to-nothing the second I quit the game. Please note that these are old games so they are not graphically or computationally intensive. The MacBook gets noticeably hot to the touch, yet I don't recall seeing its thermal state drop below 'fair' when monitored via the macOS Instruments app. Performance is not an issue; I can play the game, connect an iPad as a secondary display using Sidecar, stream video and perform various other tasks smoothly. I am curious as to why CPU usage would skyrocket. Is this a false reading or is this going to damage the CPU in the long run? What can I do to mitigate this? Thanks! I am running Parallels Desktop for Mac 1.5.0 (20116) on macOS Catalina 10.15.4 on a 2017 MacBook Pro (3.1Ghz Dual-Core Intel Core i5) with 8GB of RAM. I am virtualizing Windows 10 Pro (x64)(v1909). I have configured the Windows machine down to be very slim. No network connection, no bloatware, works very well (1 assigned core, 2GB of RAM under typical use. I have tried various other configurations consisting of more or less RAM / more or fewer CPU cores but performance is good no matter what - it's just the CPU that reaches or exceeds 100% usage).
