That's wierd...

http://forums.ngemu.com/1601556-post535.html If that helps there is my savegame.

No, sorry. I don't have tp. Can someone who does comfirm this?

it was tested by other members of the forum and they had the same results:

ok. someone will start working on it when they notice this issue report.

This isn't bugged it's just a very heavy place to run for Dolphin/computer

But it was fine before he beat it...

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.

That's possible. I can't remember if it's nighttime the first time out but it could
be. But it slows down even if you don't have a visible drawing distance - like just
when you come out of the gate at Lake Hylia it's just a wall but still very slow.

just use wireframe to see what's going on. probably a mass of vertices somewhere,
just poor programming on the game makers' part :p

I imagine that it has to do with the big amount of polygons loaded. A reason which
could explain why fps drops more is: the game preloads all of Hyrule field, and
dolphin tries to render all the geometry instead of rendering as the user gets to an
area.

yeah, technically, we COULD lower the draw distance...but that would be cheating.

uh, and how would we do that? :> The gpu is just sent a scene to render...trying to
"lower the draw distance" would be a massive, ugly hack afaik

Indeed, I'd rather take the slowdowns than pollute code. Real GC hardware doesn't
budge, so I guess theres still a lot to optimize :)

I didn't say it would be easy...but it was a bad idea anyway.

Its not gameissue,its bug in the code. Using direct3d and enabling any hack gives
fullspeed.

This is unrelated to issue 1436.

Well... Not realy. After the goron mines the fps still goes down to half the normal
speed.

Usually the newer issue is merged into the older issue, no?

there isn't really any important info in either of them, and the other one already had a better title :P

It seems likely that the Wii GPU has built-in occlusion and culling that the emulator
is missing.

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
mentioned?

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
to help.

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?
Hewlett-Packard
Intel Core i7
x64
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.
