Performance issues with TLOZ:Twilight Princess (Gamecube Version) [SOLVED]

[Umbrosus]

So i recently started playing tloz:tp (gamecube version) and whenever im in lanyru province of huryle field, the game's fps drops down to 15FPS.
I have tried to lower native resolution, switching graphics backend as OpenGL but that didnt help either so i have to stick with Direct3D 11.
also i have tried out using ubershaders but it didn't improve that much, only about 4 or 3 FPS. overclocking made it worse (same thing with switching backend to OpenGL)

In other places the performance is solid 30FPS so any help with this?
