GX 70 - Mantle not working Due PowerXpress: Disable iGPU / set primary GPU

Question

Hello there,
I am a proud owner of the MSI GX70. Is there a known way to disable the iGPU from the APU?
The APU part is registered from the Catalys Driver as Primary 8650G Graphics Adapter,due the way PowerXpress Works, most games register this iGPU as Primary and only Card present.
Normaly it should work to disable the iGPU or set the Primary Card to dGPU , on systems from HP , this works well.
The Problem is that the Catalyst is not registering the 8970M as present in the System ( and also not BF4 ( even if the 8970 is running on Max the Game registers only the 8650G ) or the Star Swarm Demo ) because of this behaviour.
Therefore the speedpush through Mantle ( measured on a nearly identical HP Notebook ) from around 20 - 40 % are not reachable till a) MSI comes up with a way to set the Primary GPU or at least disabling the iGPU in any way or b) AMD comes up in xx Months with a driver Capable to see the secondary card.
Has anyone seen a solution?

Hello WoFNuLL,
I would like to recommend you to set this function at AMD Catalyst Control Center,
choose the switchable graphics and select high performance discrete graphics to use.
Hi BlueAlexFPS: This will not work, as the Graphics Driver registers everytime the APU Part to the Game Engine, even if the Dedicated GPU is already running ( tryed this by giving BF4.exe High Performance and the Windows Calculator also , startet the calc, saw the switch between the GPUs and started BF4 -> BF4 still sees only the 8650G iGPU
@highwind85:
This is what i already knew, this topic was meant to bring some attention to MSI , that an option to disable the iGPU  in the Bios or via software would be a solution for this problem ( and other Problems regarding reigsering the Wrong gpu in the system ). The problem was solved on other systems with identical hardware in this way.
