Asus ROG not running games?

So nobody else seems to have this problem but my 2,000 DOLLAR GAMING NOTEBOOK is running like a 500 dollar gaming computer. I'm thinking about buying a desktop but I want to see if I can fix this first. What can I do to make my PC run minecraft and games like that like this

You should be a little more specific about the problem you are experiencing. Even a $500 computer can run Minecraft at high settings with the right components. The game was designed to run on low end systems.
