having stuttering while playing twilight princess

[Suntonk]

hello, i booted up dolphin today and now I'm having an issue where the game's stuttering when I got to Hyrule field or other open areas with enemies
I didn't have this before today,

I'm not sure why is it now happening but any help would be appreciated

As the player progresses through the game, Hyrule Field will become progressively slower. To fix this, enable the "Hyrule Field Speed Hack" in ISO properties (right click the game in the game list > Properties > Patches tab > Hyrule Field Speed Hack).
