CSGO laptop bug steam?

I downloaded steam to my laptop and then got csgo global offensive. The only problem is that when I start it and the main menu is jerky and when I start a game it loads very slowly and when it is loaded you can only see the other tabs that I have opened but the game is on and me hear the sounds of the shots and so but I don't see how the screen is transparent. Can you help me there?

It may well be that the laptop simply does not have enough power to pull CS: GO properly. This is indicated by the lags, for example.
