Hmm. Maybe gnome is not correctly using hardware acceleration in your machine¿? In my experience, gnome is perhaps the smoothest DE though it is heavier in resource usage than XFCE, MATE, etc. It does stutter and drop frames when the system is seeing very heavy resource usage.

Edit : when I am using the powersaver settings given by power-profiles-daemon, gnome does stutter a little. This corresponds to amd-pstate being active with the scaling governor set to powersave and the energy vs performance hint set to save power.
