hi,

i have a problem, i have AMD dual Graphics with AMD Radeon HD 6620G + 7670M (1GB)

Outerra use only the 6620g and i have no chance to use the 7670M.

why?

Applications can't choose the GPU in OpenGL, there's no function for it. We are given an OpenGL context from the system, so it completely depends on the drivers.
You should have a way to select high performance GPU in Catalyst.

From what I remember - necro told me you don't have the power section enabled in Catalyst? Maybe because you've disconnected the battery?

no i cant select the high performance gpu, because i have no option or menu

and i have no power section in catalyst, thats the problem

This is really something that should be asked on AMD forums, as I said we don't have any power over it from inside the application. Here's a good article about the switchable graphics: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03048374&lc=en&cc=us&dlc=en#N58
Can you see the screens shown there?

Select a Recent Application and click the green or red button to change the default graphic solution between power-saving and high-performance.
Or click Browse to find the executable file for the application you need to configure.
Figure 4: Catalyst Control Center - Dynamic Mode Switchable Graphics
Catalyst Control Center Switchable Graphics window

i dont have that window, the other window i can see
