They happen randomly and when I move the mouse over its window in random locations. I am using the latest progwrp.dll offered in the Readme and the latest release of Supermium.

Which Readme do you mean ?

I'm trying to reproduce on XP x86. Is your CPU single/dual core ?

Also show us CPU usage history screenshot from ProcessExplorer or Task Manager

Zero3K commented 7 months ago

The VM is set to single core.
Here is the requested screenshot:

The first spike happened when going to a webpage. The second one happened when doing what I described in the first post in this issue.

Ok. You must determine which Crome.exe process causes this. (If you are using Chrome in multiprocess-mode) And then show us expanded CPU usage history for that process from ProcessExplorer or ProcessHacker. Because this will be more informative. They show usermode/kernelmode times in different colors for a single process. Looks like synchronization issues. and may be related to interaction with VM.

Show us something like this under high load by mouse movements and so on. :
