Dolphin Revision question. Specific rev needed.

[Swiftfreddy]

Hello,

Simply put, is there a revision of dolphin that has the OpenGL improvements but still uses the old audio system?


Using the latest revision of Dolphin, it runs 100% and I am having no issues but I have a friend who wishes to watch so I am streaming it for him.

I understand that streaming and Dolphin aren't going to be optimal together as they are both huge CPU hoggers.

I have been using 3.5 for the stream, I get maybe 80% speed at best but it is watchable because the audio isn't warped.

With the latest revision I get a higher speed but the audio warping makes it unlistenable.


To sum it up again, I just wish to know if there is a revision that has both the old 3.5 audio (I prefer the bugs over the time-warping) but has the OpenGL improvements.

I have looked through the revision lists but they are so massive, I will be looking through them after posting this to see if I can find anything.

Thanks in advance for any assistance.

Do you have an application called "Boom"? If so, uninstall and try again as that has caused audio warping before.

[Swiftfreddy]

I don't have Boom installed. I have taken a look just in case but I definitely don't recall installing it.


I thought the time-warping on the audio was normal if you aren't running at 100% speed with the newest revision.

When I run at 100% everything is perfect however streaming means I can drop a few frames and then at 80-90% the audio seems to slow down to compensate.

However I never experienced this on older versions of Dolphin, presumably when the audio worked differently.

I'm not sure exactly which OpenGL improvements you're referring to since there have been so many improvements to Dolphin since 3.5, but to give you a simple answer to your question: No, there is probably not a version that has both of the things you're looking for. If you're looking for a specific improvement and that improvement was implemented before the big audio change, you will be able to get an old development build that has it, but it's unlikely that that's the case. If what you're interested in is all of the OpenGL improvements... well, that's not going to be possible.

Yes, this is correct.

[Swiftfreddy]

Thanks.


I can't recall precisely the improvement. I think I remember reading that there was an improvement to OpenGL or a hack that caused a big speed up if you are running a Nvidia card.


However, it could be the new audio system that is actually giving me the speedup or any other improvement since 3.5.


I have been trying to look for the last revision before the audio change, that way I can test and see how it runs.

But there are so many revisions to look through and the notes are sometimes cryptic to me.


I will continue to look but if anyone can point me to the correct revision that would be brilliant.

According to the following article, the audio change happened for most GC games in 3.5-78, with Wii games happening later in 3.5-1154: https://dolphin-emu.org/blog/2014/11/12/the-rise-of-hle-audio/

As for the OpenGL improvement... Hmm, I haven't been keeping that much of an eye on the graphics side of things, so I'm not sure what it is. It sounds unlikely that it was added earlier than the versions I mentioned above, though.

What are you using to stream (I ask as you and I appear to have the same CPU model and I could run some tests myself)? Could probably attempt lowering some of the encoding settings on that and see what happens

>Also, do you have HyperThreading turned on or off?

[AnyOldName3]

You could also switch the audio backend to OpenAL and turn the latency up. This will help with audio stuttering.

[Swiftfreddy]

Thanks for the further support. (I tried OpenAL but the audio seems to completely warp or fail to work, maybe i'm not using the right latency.)


I have been experimenting a bit and I have managed to get to a point I am happy with.


In the end I am using the latest dolphin revision and am streaming 480p 25fps 1200 bits and the speed varies between 90-100%.

The sound time-warping is there ofcourse but I have gotten used to it, at this point I will take the smoother gameplay over it.


I recently upgraded to fibre broadband and was just hoping I could improve the stream quality for my friend or anyone else unlucky to stumble across my stream.

It isn't really feasible to go any higher than this with my current CPU, hopefully I can stream non-emulated games at a higher resolution and bitrate at some point so atleast there is that.


The only other question I would have is if it would ever be considered to have the old audio emulation as an option in future Dolphin builds. I imagine there are a multitude of issues regarding that but in an ideal world, having the option would probably be helpful to those who can't emulate at full speed.

Anyhow, thanks a lot guys.

Will the broken audio emulation ever return to dolphin? No.

Quick explanation as to why: Games rely on audio timings. Audio goes full speed while game lags = bad things happen.
