I disabled all my extensions prior to posting.
On my W8.1 Lenovo T560 laptop with 8GB ram and 256 GB SSD, this site goes into very high cpu, 70% to 90% as monitored by sysinternals/processexcp. The web page takes a long time to process the data, which is something I've always just had to wait until it got caught up. When the page is not being displayed, the cpu goes down to normal, around 1%.
But today I noticed quite by accident that my other laptop, Lenovo T460 on Windows 7 with similar hardware does not have the high cpu problem on the very same web site. Both of these laptops are brand new but I just prefer to run older windows OS's due to my older applications that I use.
It's very strange that the T460 has no problems at all with this site.
I run my laptops very tight as monitored by processexcp and very few non-system apps are running in background.
There's no way I can monitor extension cpu use, but as stated above, I have all extensions disabled for this posting.
I would really like to know what is the cause of the high cpu.
Anyone reading this, just click the link above and look at your cpu to see if it's overly high or just nothing at all. If you have the high cpu problem, maybe you can track it down to some hardware setting, or ???

Actually you can - Opera internal Task manager displays resource usage breakdown, press Shift+Esc (inside Opera) to open it.
I would guess you have some graphic driver (in)compatibility problem.

My stats - about 6% CPU / 6% GPU from that site. Old Win10, Opera dev stream.

On both computers, goto the URL opera://gpu and see what's hardware-accelerated or not. It could be that hardware acceleration is working on the 460 and not on the 560. Or, maybe the 460 isn't using hardware acceleration while the 560 is and the 560 is using more CPU because of it for some odd reason.

Either way, on the 560, you can goto the URL opera://settings/system, disable hardware acceleration, restart Opera and test things out again to see if it makes a difference.

Or, with hardware acceleration turned on, you could goto the URL opera://flags/#use-angle, change the flag to a different value, restart Opera and see if it helps. You can also test with the flag at opera://flags/#ignore-gpu-blocklist enabled to test if there's a difference. Revert the flag to default after you're done testing though. With each difference configuration, you can check opera://gpu to see what it says.

The page uses up to 42% of my CPU though for a bit for what it's worth.

Thank you both. That's just the kind of info I'm looking for. I'll try this stuff and get back to you.

I forgot to add; for high cpu, you have to start the time roll, by clicking the slider bar(you may have to scroll down to see it, on the left).

So what does this mean????

@pdw Hardware acceleration is disabled. Try enabling it and see if anything changes.

@pdw Also try installing the latest drivers for your graphics card.

The opera://settings/system showed that hardware acceleration was turned off. I enabled it and, Voila! cpu went down to 2%.
Many thanks to the replies. I couldn't've done it alone.
