Bad Performance with Dolphin 4.0.2 and Mario Kart

[hsdneo]

Hello,

i want to play Mario Kart on my Gaming Notebook, but the sound stutters and the game is very laggy. What are the best settings to play it?

I have a Schenker P503 with an Intel Core i7-4700MQ, a NVIDIA GeForce GTX 780M and 16 GB of RAM. Actually i have lowest resolution and no AA and other things. I did the setup from the performance guide, but it is not playable at the moment.

Any1 can help me?

Thanks
