Notebook Video, Display and Touch

Ok I'm having an issue with my PC

First of all I must mention english is not my first language. Now, going to the issue, I have HP Pavilion 15-P002LA (F4J00LA), with Windows 8.1 (x64) installed, Processor is AMD A8- APU with AMD Radeon R5 Graphics, BUT there is an AMD Radeon R7 M260 as a "Linked" (Dedicated) GPU. It's said that such GPU is used on high performance programs such as games, by example, but I have noticed that none of my games uses the R7 M260, so I went to every forum to see how to "Enable" the Dedicated Video card and some suggestions were:
-Disable R5 from Device Manager (didn't work), instead, it gave me the default driver(?)
-Update drivers (didn't work since they are always updated)
-Understand the switchable graphics works with high graphic demand (tested with third partner software, didn't work), I tried overclocking but the only Graphic card working is R5 and R7 does not move.
-Configure the graphics to Max Performance via Catalyst (didn't work), everything is configured to run in Max Performance
-BIOS (there is no option for Graphics handling there)


Is there a way I can make my R7 M260 GPU work? As I said, I tried everything on forums, I've understood that it only works on High graphic demand which I think is a lie since every game I've ran so far gave me less than 30 fps and running only on the integrated GPU, and just saying, I've ran all my games with high graphic demand (max specs) as wells as low demand (low specs) and in low specs it gives me a Max of 30 fps on every game...

TL;DR

Is there any way I can make R7 M260 GPU work? Because it seems I have dead weight in my Laptop.
