It works with other programs, and PCSX2 uses the GPU perfectly. It cannot be defective.

Then it may simply be bad luck and Optimus doesn't like Dolphin out of all the programs you run. Not sure what the developers can do. If PCSX2 can use it, then Dolphin should be able to as well.

I did notice that it worked one time in the past... I think it had something to do with the [factory] drivers. I have updated everything to the latest [I reformatted before to get rid of bloatware that comes shipped with the system]. I did remember that the nVidia card then worked (after reformatting) with directX11 plugin. It is still weird though, other programs properly use the card, except for Dolphin. It must be some incompatibility issue somewhere... I could reformat with Windows 8 Media Center while Microsoft still issues valid keys... Though I hate it from the bottom of the heart, I already have bad experiences from Windows 8. Admin89 uses Windows 8 and Optimus as well without many problems, maybe if I follow the same way as admin89...

Did you use the drivers from the laptop manufacturer's site or directly from nVidia's site? If it's from the manufacturer's site, then I wouldn't be surprised if that's giving you trouble. It could be that Windows 8 doesn't like Optimus, and besides, I see no clear advantage that 8 has over 7, so if you have the installation disc lying around, I'd fall back to Windows 7 instead.
