cpu usage should drop significantly when you close the tab using the engine. Be sure there's not an engine still running immediately after your game ends as well since. Other than that, use an ad blocker to prevent ads from taking up resources and use a quicker browser dedicated for chess.com so you don't have extra cache or extensions also using resources
CPU remains high after using in-site engine

Thanks. Yeah, it's confusing. I must see if it's the same on Chrome. Creature of habit, I always use Edge. Might well be the problem. When it happens, and I open task manager, there's like a billion sub-instances of Edge showing under the Edge entry. Should probably also upgrade to 11...
When I analyse a game using the in-built analysis, my CPU skyrockets, but then the CPU stays high even after navigate away or even close chess.com. Anyone find this? Doesn't happen on lichess - CPU is high there too, but then dies again after navigating away. OK, PC is quite old, but custom-built and still pretty powerful.
