What to put in the video card?

Question

Video cards

Hello, I would like to set up a video card, but I don’t know why such permissions are given there, I have a laptop with 4 gigs of my memory on a geforce gtx 850m, you can even set anisotropic filtering to 16x, but I’m wondering if this is even necessary? Will it damage the graphics card or laptop? What to put there in the settings so that, without reacting to electricity, you don’t feel sorry for it, the video card works at full capacity and without damage to the card? Put Restore or can you configure it yourself?
