Emulator Issues #182

disappearing enemies from OpenGL draw distance Starfox Assault (JIT only)
0%
Description
What steps will reproduce the problem?
- get to [boss] cut scene in Starfox assault
- skip/play cut scene models will be fine
- on player control models are distorted [bones/rigs or animations
corrupted but used] - second boss [first level] off center or out of place (clipping threw the
ground) impossible to beat - after an enemy (boss or level enemy) gets to far away into draw distance
fade they disappear completely and do not return
What is the expected output? What do you see instead?
Expected to see the models as they appeared on the console. using the
emulator the boss models (presumably complex rigs/animations) boss models
are distorted or vanish for no reason
What version of the product are you using? On what operating system?
Dolphin SVC r 438 X64, Windows Xp x64
Please provide any additional information below.
Issues discovered while playing Starfox: Assault
Due to the nature of the Open GL plug in
A) when enemies get to far away into the opacity distance falloff they
cease to exist
B) There are flickering models when something is just outside the drop off
mark.
C) If a model goes outside the [scripted] drop off to far they cease to be
a game entity, IE boss models moving far into distance disappear.
I recommend adding a user adjustable draw distance, for performance and
stability of games.

I think most of these problems are caused by OptimizeQuantizers = True. Try it with
False.
Updated by the.ryoku.kitsune over 15 years ago
negative on that, i forgot to mention that i tried it in both boolean values.
Updated by Leoharantes over 15 years ago
Well, the game worked fine with the optimize quantizer = false in the older versions
like 177, but since about rev 300 or less the problem remains, with that setting
turned on or off

The issue still persists in Revision 1590, haven't tried Starfox Assault in the
latest revisions yet but I assume the same problem exists in those as well until
someone reports it. AKA Boss still impossible to defeat.

Optimize Quantizers Off Fixes the Aparoid clipping into the ground Problem and also
the On Foot Missions Player Skeleton, but it still doesn't fix it from Vanishing
later as it gets too far from the Drawing Distance, so it's still broken there.
I attached a Picture of Fixed On foot playing in Multiplayer.

seems to be jit related as the IL version works.

This is also very old. Any chance it has been fixed?

I'm not having this problem anymore in r7216. I just now beat the Aparoid.
Updated by MofoMan2000 about 13 years ago
Wait, I used D3D9 backend, I'll try OpenGL once I get back from classes…
Updated by MofoMan2000 about 13 years ago
Yeah, I didn't see this problem in the OpenGL backend, and I just played through the entire first mission. I think this issue can be closed finally.

GAH, it's still a problem in JIT, but with JITIL it's fine.

That's how it's been this whole time. ;)

Fuck. I'm stupid sometimes.

the game is unavailable to me now so I can't test any updates. my image is gone and my disc is scratched so I'm out of the loop on this issue. please coordinate with other users on this issue for testing purposes.

The "fix" ( revision 0fcf1d6197ff ) disables the jit64 faddsx instruction completely. Does anybody know what is broken in this instruction? imo we should try to fix this instruction instead of just disabling it.
So, first step would also be to check is this issue is still valid when reverting this "fix".

After hours of debugging:
The difference between Interpreter and Jit64 in faddsx is that the Interpreter checks for subnormal by doubleToFloat convertion:
https://code.google.com/p/dolphin-emu/source/browse/Source/Core/Core/Src/PowerPC/Interpreter/Interpreter_FPUtils.h#76
Jit64 itself doesn't check this:
https://code.google.com/p/dolphin-emu/source/browse/Source/Core/Core/Src/PowerPC/JitCommon/Jit_Util.cpp#387
At least disable this line recreate this issue.
As this affects all float instructions, disable just one of them because of a visual issue isn't the way to go.
btw, the affected call in jit64:
PC 8015ed00: 5.047743e-40(37c5fc6c00000000) + 5.123296e-39(37fbe4d500000000) = 0.000000e+00(0)(interpreter) <-> 5.628070e-39(37fea46280000000)(jit64)
btw2: the smallest normal float is 1.175e-38, so all args are subnormal.

It seems like it is a general problem that the Gekko's FPSCR register is only updated in the interpreter and the JITs don't update their respective CPU (on x86, the MXCSR register).
Updated by degasus over 10 years ago
I wouldn't call this a fix as it's just another workaround, but it still works fine:

Updated by JMC4789 over 10 years ago
This issue happens in D3D and OGL in Master 4.0-370. Using JIT for now, will do more testing later.
Updated by degasus over 10 years ago
JMC: There is no need to test here. This issue is well known to happen because of denormal floats. Just see my comment #28
btw: this is fixed in the ppc_fp branch
Updated by JMC4789 over 10 years ago
I just wanted to let everyone know that it seems to be only bug remaining in this game. I played the rest of the game in JIT and there were no problems.
The crashes mentioned in the Wiki + other issues mentioned here are no longer issues. Considering how old this issue is, it's not really a surprise, and I'm sure other people have tested.
This game, at least from my quick tests on Console, should be 5 stars after this is fixed :D

- Status changed from Accepted to Fixed
as ppc_fp is merged in b863e4067771 , this issue is fixed now.
