Super Mario galaxy 2: a lot of slowdown during the intro

[legolas119]

HI
I'm using the latest version of Dolphin and I tried both EU and USA version of Super Mario Galaxy 2, but I alway have an issue during all the opening: there are a lot of slowdowns, there are about 10/15 fps drop...

This is my pc config:
[color=#323232]CPU: AMD Ryzen 3700X[/color]

[color=#323232]Motherboard: Gigabyte X570 I AORUS PRO WIFI[/color]
[color=#323232]RAM: 2 x 8 GB Kingston HyperX Predator 3200-16[/color]
[color=#323232]GPU: RTX 2060 Super[/color]
