How can I config Dolphin Exactly for me

[Plermpel]

Hello,
I'm running Dolphin on my AMD A8-4500M with intergrated Graphics 512MB and external AMD Graphics. And I wan't to Play New Super Mario Brother Wii, Mario Kart and Donkey Kong Country Returns but all games have less than 25fps and the Sound is stuttering terrifying (no difference between HLE and LLA). My Processor is only runnig at 60%. My Question is, how can I config Dollphin to consider me?

New Super Mario Bros. Wii is probably the only game you're going to be able to play at full speed with that processor. Make sure your laptop is plugged in and the power settings are set to high performance. Also, make sure your "dolphin.exe" is set to high performance in Catalyst Control Center.

But why isn't Dolphin using my whole CPU Power. Even in Mario Bros. I'll get about 20fps more on my old Pentium D 945.

Single threaded performance of Intel CPUs are higher than AMD CPUs, and Dolphin is a dual core app (tri core if you enable DSP on Thread), the extra cores of your AMD CPU doesn't help that much...

Not a chance. And this is coming from someone who owned that exact cpu. You'll get worse speed on that pentium D then you're getting now.
