Is this usage of video memory normal?

Question

Video cards

Good afternoon, ladies and gentlemen. Faced a problem with video memory on the video card. When idle, about 400-500 Mb is used (total 4Gb), when the browser is launched, it increases to 700-800Mb, and further increases to 3600-3700, provided that the load does not increase too much. As a result of all this, the question is, should there be such dynamics and norms, or is it?
