"This is normal unfortunately. I think some programmers writing mouse and keyboard drivers must think that CPUs still run at 10 MHz and not at 5000 MHz like most computers can run at. They seem to over sample any mouse movements millions or more like hundreds of millions of times per second.

Moving a mouse around randomly on the screen should not need to put that big of a load on a modern CPU. ThrottleStop does a fantastic job tracking CPU usage. Maybe driver developers should stop using the same code that they were using 40 years ago. If they used the ThrottleStop C0% data, they would realize that it is time to update their inefficient driver code."

"There is likely nothing you can do about the inefficient software you have found. Sad when you need to dedicate a core running at almost 5 GHz just to manage a mouse."
