Thanks again.
On my Lenovo with Window10 which I use for work I don’t find the Processor Power Management option you are referring to but I do know which option you are talking about because I do find it on my other HP personal Laptop with Windows 11. Anyway, here I what I did on my Lenovo . I clicked on the battery icon and moved the Power Mode slider from mid to best performance for when the laptop is plugged in and it looks like this little change did the trick. My Laptop is not sluggish anymore for now. It is obvious though that Debut is a high consumer application because I can see that, in the Windows Task Manager, the Power Usage of the Debut application shows “High” to “Very High” even when not recording.
