Hello :-)
I've searched answers for this from very long time but without effects.
On Windows, Intel HD have user-friendly control panel and in 3W section it's possible to switch Intel HD performance between efficiency, balanced and best quality. It's very important when it comes to play games.
But as far I know, there is no such control panel for Linux. So - is there any way to do such thing under Linux? There is no gui to control APU - not a problem, but maybe it's possible do in terminal?
It's the only place where i can get answer - if not here then nowhere :-(
