It appears your screen is 1366x768 and the CPU/GPU is an i5-4200U. I would not expect any performance problems with those.

Or do you mean it is stuttering (skipping frames)? ** Changed in: xorg (Ubuntu) Status: New => Incomplete ** Package changed: xorg (Ubuntu) => gnome-shell (Ubuntu) ** Tags added: performance -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1779592 Title: I have video lagging errors Status in gnome-shell package in Ubuntu: Incomplete Bug description: In browser (Chrome) and VLC.
