Dolphin emulator speed dropping when playing games

When I am playing certain games in certain areas the speed of the emulation drops to about half. Specifically hyrule field in twilight princess. I have what I thought to be a fairly decent pc I am running a ryzen 5 5600 cpu with an nvidia 1650 gpu with 32gb ram ddr4. I have tried messing with all the graphics settings watching YouTube videos to see if it helps and so far it hasn’t matter if it’s top notch or bottom of the barrel graphics, it seems to still keep me at half speed in certain areas. Is there something I am missing that will help me keep the game running at normal speed?
