Let’s say that you have an Asus laptop (AMD quad core A4-5000).
This laptop has both an integrated video card and also a dedicated video card: AMD RADEON HD 8670M (1GB RAM).
How do you set so when you play a game, the dedicated video card will run, instead of the integrated one?
You can do that from bios. Enter bios and look for “dedicated video card” and “integrated video card”.
