CPU Usage Question

Just a quick question. Is it normal for your CPU usage to fluctuate up to 30% to 40% when scrolling through web pages such as Facebook and then drop to a normal range of 3% to 8% when you are done scrolling?

I'd guess so. I know nothing at all about Facebook, but my CPU just jumped from 5 to 28% when I refreshed a random web page.

Better that it did than didn't. What's the point of having firepower if you aren't going to use it?

Scrolling some web pages can be a very complex task for the browser and require considerable CPU time. It all depends on the details of how the web page is implemented.

Here are my system specs
Specification for GT75VR 7RE Titan | Laptops - The best gaming laptop provider | MSI Global

The Task Manager CPU usage is just an approx display of CPU usage for a user, it is not what is really going on which is too fast for display purposes, thus a suitable display graph is generated by the software i.e. the Task Manager.
That seems to be updated at a rate of 800 ms by the looks of it.

The fluctuations as viewed by the Task Manager could easily be 40% by scrolling a webpage.

My desktop is similar spec to your system, and I often see CPU spikes to 30-40% on more complex web pages.

Yes. It seems normal to me. The web has exponentially increased in complexity. Most webpages aren't even properly optimized and web browsers tend to hog a lot of resources too.
