I think they changed the frequency adjusting algorithm under the hood with 11. It seems to be much more sluggish on bumping core clock frequency up when a big task happens. I had to go in and lock the minimum frequency to 100% on a bunch of user laptops because they would stutter so badly any time they went from low to high CPU usage.

Sometimes I miss being a sysadmin, then I remember dealing with windows 11’s eccentricities.
