Please don't open bugs for old versions.

Version 99 is the current supported version.

There is an upstream discussion about high CPU usage at https://magpcss.org/ceforum/viewtopic.php?f=6&t=18758 I'd suggest you join in the conversation there.

Thank you for your reply.  I have another problem, which is cefsharp v86.0.241 in WinForm version  does not use separate graphics card. I have a computer with dual graphics cards. I set up high performance through win10.

This is not a supported version.

Chrome doesn't support selecting a GPU directly as as such CefSharp doesn't have a feature. A quick search yields https://support.google.com/chrome/thread/77636044/chrome-to-use-specific-gpu?hl=en

Ultimately you'll need to do your own research into this. I don't have dual GPU's

Only other comment I'll make is that CefSharp.BrowserSubProcess.exe is used as the GPU process by default.
