I have the 4k LG ultrafine connected to the Mac mini i3. I have writing programs open on each desktop and safari on last. I jump around these to look over notes etc. Jumping desktops is laggy. what's causing this? is it lack of RAM or is it the integrated GPU?

If I was to get an external GPU and keep the monitor plugged into the Mac mini, would this fix the issue?
