Emulator Issues #720
Zelda TP slows down dramatically in Hyrule Field after Goron Mines
What steps will reproduce the problem?
1. Beat Goron Mines or get a savegame (I can supply one), and visit
outdoors areas. Whereas before speed was around 13fps, now it drops to
4fps (6 with efb hack).
What version of the product are you using? On what operating system?
Tried it on XP32 and Vista

I can confirm this, but i rather think its a problem of viewing distance.
The first time you go to Hyrule Fields is while it is still covered in the darkness,
and even after Kakariko when returning to save Colin the field is shown at night.
After Goron Mines, the first time I went back out it was broad daylight - with an
incredible viewing distance compared to night/darkness view.

It seems likely that the Wii GPU has built-in occlusion and culling that the emulator
Large areas are going from running at 100% (150% capable) to about 30% to 50% in the
areas mentioned on my machine, regardless of what direction I'm looking or what is
actually visible. It almost sounds like it is missing basic culling.

Any way to test that in Dolphin to see if that is what is causing these slowdowns?
Are you familiar enough with coding to add basic support into the emulator if these
features are indeed missing?
Is there any way to determine if the actual hardware even supports the features you

No, I'm providing a possible avenue for the developers to investigate. It seems likely
because when there is a view distance limit due to the fog when I first went through
the fields, the framerate was moderate. But when I could see significantly further,
the framerate dropped. Also, it doesn't matter what direction I'm looking in, directly
at the ground should exclude most of the map from being rendered, but it doesn't appear

Well, I think that's not a viewing distance problem (fog, or night would not help). That's just because, while youre playing the games it unlocks Hyrule Field parts, when you first enter HF in the game, its very basic, with poor details and reduced area, after Goron mines it's larger and fully detailled. Maybe at this point of the storyline the game is loading the whole Hyrule Field and stuff that wasn't loaded before.
Someone tested the Hyrule field speed hack? How does it works?

Every time I update the Dolphin emulator this issue seems to be worse for me. I updated from 3.0 to 4.0 and it's even worse.
Also, in 3.0 when I go to howl along with a stone it freezes as soon as I press (A). I usually can get around this by saving state, then disabling lighting and other contributes to the quality I can SOMETIMES make it work. Then keep loading up the saved state and trying it every time till it goes through.
I understand Zelda: Twilight Princess is a HUGE game and Dolphin seems to have a very tough time running it, but at the very least I'd suggest a way to improve something to make it work a little better.
My PC Spects?
Intel Core i7
996 GB Disk Space
8.0 GB RAM
And my CPU is almost always just 15% when I run the game. So it has TONS of CPU space to use just doesn't seem to use it.
So yeah any suggestions on my end would help out.
