Problema Intel GMA 3600 CPU high

Hi all, I have installed the i3wm version on an old Atom n2600 with 4gb and 120gb ssd. I have a high usage close to 40-50% without use, process picom is high, I have read that it may be due to the graphics card, it has an Intel GMA 3600, how can I verify or install this graphics card correctly? Thank you
