Why does a discrete graphics card not work on a laptop?

Question

Video cards

The video card behaves strangely, it is used at 2%, then sharply at 100% (no load, just on the desktop), the maximum uses 0.2GB of RAM graph. processor (from 2.9), the memory is also allocated 0.2GB out of 1. The processor graphics work under load. I reinstalled the drivers, put high-performance in the nvidia control panel .. blabla.
What could be the problem?

Answer 1

In theory, drivers from the laptop manufacturer's website should solve your problem
