Zelda TP only works at normal speed if using direct3d and projection hack
0%
Description
What steps will reproduce the problem?
1.Zelda will run very slow in hyrule field even on very fast pc
2.Using direct3d and applying ANY projection hack will improve the
gamespeed immensely
What version of the product are you using? On what operating system?
As far as I know,issue is the same on any operating system or any dolphin

It gives you full speed in any area that is not Hyrule field
Hyrule still has the slowdown problem, causing you to go down to 15-20 FPS.
But it's great really, every other area is playable at max speeds (1080p with 4xAA
and 16xAF)

Wow, weird.
I have no idea why this happens. It shouldn't make a speed difference, but it clearly
does, for me too.
Gonna try to figure out why and make it so you don't need to set the projection hack.

Also noticed speed improvement is bigger if using fullscreen then windowed mode.
I even tried windowed mode in much smaller res ( 800 x 600 ) while using my native
res for fullscreen ( 1680 x 1050 ) and fullscreen still was faster.
Very weird !

pua4life: those sort of slowdowns in windowed mode can be a driver issue.

Some ATI card dont kick in full 3D clock while in windowed mode.
This may explain the fullscreen speed.

Well I ran rivatuner monitoring utility and card ran at normal speeds.
So its not that. Probably driver issue.

It's been some time since this issue was discovered..
If it's bug in the code is it really this difficult to fix ? This is great speedup I
am sure it may benefit other games beside TP
Some user on the forums posted this,it may be of some help ?
Code:
bPhackvalue1 = 1;
fhackvalue1 = 0.00007999997f;
bProjHack1 = 1;
//broken minimap on OGL - speed-up on D3D
Code:
bPhackvalue1 = 1;
fhackvalue1 = 0.00007999998f;
bProjHack1 = 1;
//working minimap on OGL - no speed-up on D3D

not applied !

This is not fixed. Hyrule field with the Golden pyramid = Big slowdown, before pyramid
and after it's fine.

Also in Wii Sports, in OGL now there's the old slow down, I got 25-30 fps now, when I
was able to get full 60fps.
No problem in D3D, a part some graphics glitchs.
