Yes, when I tried this with Chrome it also did the same thing. Firefox is better to be honest.

same with me and i am using windows 10 and a core i7 with a 1650 graphics card, i tried microsoft edge out of curiosity and now its using 10 percent on chess.com where as with chrome its 90 to 95 percent unplayable especially with arcade animations.

It's likely due to the animation type. Is hardware acceleration on in your browser? You might try toggling that to see if improves things

Are you able to verify whether or not perhaps it is running an engine analysis for some weird reason? (probably not the reason, but just a thought in case you don't figure out another reason for it).

i was able to figure it out, i needed to turn on graphics acceleration on my google chrome apparently if its off it puts way to much workload on the cpu and the gpu is not able to help or at least not as much now the cpu is running on 8 percent problem solved im guessing its same for other web browser but just search it up on settings might have a different name.

Any known fix for this?
The animations ''Natural'' and ''Arcade'' use up alot of gpu so i would suggest turning them off and simply (switching it to no piece animation). also check if your browser is using your gpu on the browsers settings it usually is called ''Gpu Acceleration'' or ''Hardware acceleration''. hope that helped.

Hey! Thank you for the tips! Unfortunately, I already tried those before, but tried them again just now to make sure! Still doesn't work. It is strange, my CPU usage goes very high for the first minutes of playing, then it goes back down. I never had this issue until about a year ago. Also it happens regardless of whether or not I have GPU/HW accel on or off. =\ oh well
Hi,
I'm using Google Chrome on Windows XP and everytime I have a chess.com tab open, the CPU-usage goes up (fan is roaring, task manager shows 90% cpu usage for the chrome process).
This does not happen on every chess.com page, but on: "My Home" and virtually every page that has a chess board drawn on it (games, analysis board, conditional moves).
The CPU usage won't decline unless I close the tab.
I guess there must be s.th. going on with a JS-Script.
Anybody else experiencing the issue?
Greetings,
Roman
