Acer e5-551g-t88p - how to switch my integrated for dedicated graphics card as a primary one

[mephesto]

I have acer e5-551g-t88p and i can't run most of the newer games or can but with very low fps on low quality settings.
I think that's due to the fact that my primary graphics card is the integrated AMD Radeon(TM) R6 Graphics and not the AMD Radeon R7 M265 2gb ddr3, so my question is how do i switch them and if that really is a solution to this problem?

There is likely a setting in the BIOS that will allow you to switch between the two. To get to the BIOS settings, you shut down and typically press one of the F* keys repeatedly. Normally it's either F2, F8, or F11.

I've already tried that, but i can't seem to accses the advanced settings, every pc seems to have different bios thingy...
