Troubles to run Wii games with Dolphin

[Sechs]

Hi guys !
I’m quite new to the world of Dolphin. I downloaded it 3 days ago and tested some games on gamecube, including mario sunshine and wind waker. It seems to run smoothly, fast enough to be played.
But I then tried SM Galaxy on Wii. I tried lot’s of settings, but the game keeps lagging, and rendering around 40 fps and 50-66 % of its speed.

I have an early 2017 razer blade, here are the specs :
Processor
Intel Core i7-7700HQ (Intel Core i7)
Graphics adapter
NVIDIA GeForce GTX 1060 (Laptop) - 6144 MB, Core: 1404 MHz, Memory: 8008 MHz, GDDR5, 378.92, Optimus
Memory
16278 MB  , DDR4 Dual-Channel
Mainboard
Intel HM175

Here are the screenshots of my dolphin config :

I’m looking for advices to make my Wii games run smoothly, I think I missed something about dolphin config.

Best regards,
Sechs

First off, try using the latest development build of Dolphin - that alone can improve performance considerably.

If that alone isn't enough, then try changing the rendering backend between OpenGL, Direct3D 11, and Vulkan (Direct3D 12 on Dolphin 5.0).

Reported for piracy, first screenshot shows at least 2 scene releases.
