Some settings and slow games - eckso - 01-24-2016

Hello, I was tidying up the Dolphin.ini file and found some settings that are different from the default, I don't know what they are for so maybe someone can help:

Code:
HLE_BS2 = True (default false)
GPUDeterminismMode = fake-completion (default auto)
[DSP]
EnableJIT = False (default true)

I'm also having some speed issues with a few games. Beyond Good & Evil is slow even when using Dual Core (HLE audio as well). I have SyncGPU disabled. The only condition I have is to run it with VSync enabled since I can't tolerate tearing.

Same with Rebel Strike. Here things are more complicated since it requires LLE audio, and Dual Core to be off (won't work with it on), I even disabled VSync but still slow:
Code:
[Core]
DSPHLE = False
MMU = 1
DSPThread = True
CPUThread = False
SyncGPU = False
[Video_Hardware]
VSync = False

EDIT: BG&E goes fine in Ishiiruka, Rebel Strike somewhat better, but still slow (~40fps).

From github:
BS seems to be mean "Bootstrap", aka IPL. You can use the Bootrom (IPL) with dolphin, or else it HLE's it, wich is the default if you haven't got the IPL dumped. Also, the IPL can be used to get the systems fonts, if homebrew uses it.
GPUDeterminismMode might be just a fallback if the gameini doesn't have it. Why it is set, i don't know, as i just searched for it on github and couldn't find anything really. (I just looked fast)
I guess that DSPEnableJIT is the "DSP LLE recompiler" in the Audio settings. Once from the code and from the name ("recompiler" is like a JIT, isn't it? Also, DSP is audio, so that is the only option i know about)
HLE DSP is already good for the common games, LLE is just for accuraty and games that depends on it or the HLE fails at (eg. i heard that they made a piracy check by checking the DSP if it is real, wich only is in LLE and own dumped)

Thanks for the help, although it only made clear with the first setting.

I'm still interested on performance on the 2 mentioned games. Maybe I should post on their respective threads? I just wonder because the BG&E thread is blank and I feel like necroposting.

necroposting rules don't apply in the game threads. The Rebel Strike thread has a mine of useful information, you can go check that out, but generally it's very hard to get running at full speed. check it's Dolphin wiki page for more specific settings as well.

RE: Some settings and slow games - eckso - 01-29-2016

Dolphin Wiki is far, very far from the end-stop of game configuration, I know because of this.

BG&E runs very slow, but this issue is not addressed on the Wiki so that's a thing. Rebel Strike is understandable since is a very demanding game and just recently emulated.
