Photoshop CC only detects Intel GPU instead of AMD Radeon (Win8)

Question

Hi,
I am running a pc with Win 8 and Intel i7-3630QM CPU.
On my system I am running 2 Video Cards, both Intel HD Graphics 4000 and AMD Radeon HD 7670M.
I set my switchable cards to high performance when using photoshop.exe, but when I check in PS Preferences, the detected Graphic Processor is Intel HD 4000.
How can I set my AMD radeon for higher performances?
Thanks
Cecilia

With dual-GPU's, it is often necessary to disable the Intel GPU, usually in the computer's BIOS.
Many laptops have dual GPU's, to allow them to run with low power consumption (on the Intel), and then they automatically switch to the AMD/ATI, or nVidia GPU, depending on which chip is installed, for more graphically intensive work. That often works well, but not in all cases. In most of those anomaly instances, the switching in the BIOS takes care of the issue - inconvenient? Yes, but often necessary. Some users have had good results by disabling the Intel in the OS's Control Panel, rather than at the hardware level with the BIOS.
Good luck,
