High GPU Usage When in Main Menu

Hi. I’m writing since I have been noticing, that my GPU usage is about the same rate when in-game as in the main menu (About 45-55 usage), which I personally find ridiculous high (When in the menu that is). Why not tone down the graphical stuff that is running in the background or something, and save some graphics card lifetime, that we could use playing the game instead.
Don’t know if I’m posting it in the right category, but technical support just felt right.

Info:
Got a GTX 1080 and running custom with 100% texture and high in most settings (Just to spare my card a bit)
