Question What is Chrome doing with so much of my CPU?

Hello,

So earlier I was doing my Sunday afternoon browsing of manga's and noticed web pages I was on where "laggy". I know sounds weird but their responsiveness was similar to what you see while playing video games and have high latency where you press a button and notice your character acting out the action of the button you pressed after a random delay of where between quick and an eternity long. So I checked a few other pages and closed any tabs that I had hoarded and were collecting dust. The lag persisted on every page. So I thought maybe it's time for my monthly reboot and updates. Turns out everything is up to date and I just rebooted.

After it comes back up the lag is gone but my laptops fans sound like it's trying to learn to fly and take off. It's a relatively beefy gaming laptop and it's visibly putting in effort running just chrome. So I got curious and checked task manager to see what's working my computer so hard. It was using about 15% cpu of which everything besides chrome is using about 1% meanwhile chrome is using the other remaining 14%. I checked my tabs, all I have open is email, calendar, about 11 tabs with just text, 4 tabs with Youtube videos that aren't playing. Meanwhile, in task manager, when I expand the chrome process, it shows it's running 43 chrome processes 3 of which using about 4-5% of the CPU each but I cannot check what they are beyond just being Chrome. So it got me wondering, what exactly is chrome using so much of my CPU for? I am no genius but I don't recall web browsers ever needing so much computing power.

I am wondering if there is anyway to dig into what these individual processes are doing? or if this is even out of the ordinary and I am just basing my assumptions on older versions of browsers which weren't as resource demanding.
