1. Add this to /etc/environment: CLUTTER_SHOW_FPS=1
2. Reboot.
3. Watch the log: journalctl -f /usr/bin/gnome-shell
all sorts of values anywhere between 3.74 fps and 50fps when running vkcube from the Vulkan SDK and around 30fps when playing YouTube in Mozilla. I never saw 60fps (my monitor is capable of more than that).
