Problems with FPS in Twilight Princess(GC)

[Enlapse]

Hello everybody!

The problem I have is that when I boot the game and go in-game, everything goes well. 30 stable FPS. But after a while (specially, but not only on cinematics) this drops to 15-20FPS as the best possibility. If not in cinematics, it happens while moving or rolling. I thought that was my setup that couldn't run it correctly, but after seeing people with lower specs than me running it with even harder configurations, well, that made no sense to me.

These are my specs:
-> OS: Windows 10 PRO
-> GPU: GTX1050 4GB
-> CPU: i5-8250U @ 1.6GHZ
-> RAM: 8GB SO-DIMM (single module)
-> BUILD: Dolphin 5.0-9111
-> Laptop: Medion Erazer P6689

And I think that's all about my specs. This is my configuration, so maybe I just have something incorrectly selected.
-> Enable Dual Core
-> Speed limit 100% (normal speed)
-> CPU Emulation Engine : JIT Recompiler
-> Nothing selected in ADVANCED tab.


Also, I haven't reach Hyrule Fields yet, but as the wiki said, I also have activated the hyrule field hack.

Finally, I have checked if the problem was my GPU or my CPU to see what could bottleneck it, and it looked like my GPU (while the drops happen) gets at 100%.

I have updated my drivers (even the GPU ones) and nothing happened. 

I think that's all. Thank you for the help in advance!
