Using AMD Dual Graphics (select models only)
The AMD Dual Graphics feature allows the AMD accelerated processing unit (APU) and the discrete
AMD graphics card to work together. When AMD Dual Graphics is enabled, graphics performance
improves over the performance available using only one of the graphics devices. This improvement
applies to DirectX versions 10 or 11 (DX10 and DX11) applications operating in full-screen mode. In
windowed mode or when running non-DX10/11 applications, the system operates in a manner similar
to Hybrid Graphics.
For more information, see the AMD Dual Graphics software Help.
