Is there a keyboard shortcut to show or hide 'FPS meter' in Chromium versions 60+?
The FPS counter, being part of the DevTools, can be toggled programmatically over the Chrome DevTools Protocol (CDP). An example using Puppeteer is available here on the Google Developers site.
So a clumsy but working solution would be writing a script that toggles the FPS counter over CDP, and assign a hotkey to it in your OS. You might want to check the awesome-devtools repo to choose a CDP client in your favorite language.
maybe this solution is useful for you ,first download an extension called FPS extensionthen in extensions panel go to keyboard shortcuts and add a shortcut for this extension,this way you can turn it on and off when ever you want. hope it helps
You can enable that in the Dev Tools area via Ctrl + Shift + J > Console Drawer > 3-dot menu > Rendering > FPS meter.
There is no keyboard shortcut for this, I'm afraid.
