When playing Fifa 18 the game lags on low settings even though my laptop (Dell Inspiron 15 5000 gaming laptop) meets the requirements. When I go to the AMD settings menu in system I see that there are two graphics cards AMD Radeon R5 (which says primary) and Radeon RX 560 (which says linked). I would like to know how to activate the Radeon RX 560 or how to set it as primary.
Here are my laptop specs: AMD A10-9630P Radeon R5 processor, 8GB RAM, 1TB Harddrive, Radeon RX 560 graphics card, Windows 10 64-bit.
