why CefSharp disable GPU can reduce CPU usage？

code

 // NOTE: For OSR best performance you should run with GPU disabled:
 // `--disable-gpu --disable-gpu-compositing --enable-begin-frame-scheduling`
 // (you'll loose WebGL support but gain increased FPS and reduced CPU usage).

why “you'll loose WebGL support but gain increased FPS and reduced CPU usage”

i think it will reduce GPU usage，its a typo？

Read the linked post.

Are you using OSR?

The upstream example has changed slightly https://github.com/chromiumembedded/cef/blob/2cd405baac5cbef7c5d4583be14ce64a3d6eed9f/tests/shared/browser/client_app_browser.cc#L53

CefSharp should update the examples to match.

If you are having performance issues then test with https://github.com/cefsharp/CefSharp.MinimalExample for a comparison.
