Hi, I have a lenovo laptop. It has a integrated radeon R4 graphics card with 512 mb vram and it also has a discrete graphics card - amd 530 with 2048 mb vram. The problem is that whenever I play any game or use any demanding software only my integrated graphics card is being used so I get very low fps. I have updated the drivers of both the graphics cards and my amd software is also up to date. My battery settings are also set to high performance. Please help.
