My laptop has 2 graphics cards can I enable both of them?

[skilltroll]

Hello, I never realized that my laptop has 2 gpu's inside, one intel graphics family and a nvidia gt520m. I looked at the settings on the nvidia control panel, the intel one wasnt enabled while the nvidia was. Is it possible to enable both of them? And why are there two gpu's?

Thanks.

No, the Intel GPU is an integrated GPU, this can be used as a backup if the nvidia failed. But intel graphics will not allow another graphics card running along it because its part of the CPU. Even if you could it would bring minimal performance differences (1-2%), And the reason why there are two is because the intel processor comes with an integrated GPU if already don't have one.
