A program that lowers the graphics?

So I have a kack laptop said in good German and therefore I wanted to ask if there's a program that screwed down the graphics for various games because I already screwed everything down in the game settings

You do that either in the game yourself or via the windows display settings because you can change the resolution

In the settings of the game and screw down.

You can set in every game. There are e.g. The Nvidia control panel (for Nvidia cards) where you can tweak.

I know
