Small Sound delay with Model 3 games!

[wild-child83]

Hello everybody,

I just been using Sega Model 3 emulator and it's looking great but I see that Virtua Fighter 3 and Fighting Vipers 2 has a small sound delay.
When you hit somebody or you fall on the ground you can clearly see that the sound has a delay.
Also when I check on youtube I see on all video's that are using the Model 3 emulator sound delays with virtua fighter 3:

Original Hardware: https://www.youtube.com/watch?v=ihBCn5hfOJQ
Model 3 Emulator: https://www.youtube.com/watch?v=uWajxxah1FU

I used different resolutions and settings but I can't get this problem solved completely.
Is their a way to fix this or adjust this or do I need to wait for a fix.

UPDATE:
I tried different settings and it seems that with these settings i got the best results
When multithreated = 1 I got a bigger sound delay with the games than with multithreated = 0
I used now these settings for the best results:

PowerPCFrequency =49
GPUMultiThreaded =1
MultiThreaded = 0
MultiTexture =1
EmulateSound =1
New3DEngine =1
FullScreen =1
Throttle =1
ShowFrameRate =1
FlipStereo =1
WideScreen =0
VSync =1

Also Sega Molde 2 emulator also has a small sound delay problem so its not only with Model 3.

I also have a sound delay compared to the original hardware video you linked (assuming the videos audio isn't out of sync). Those settings don't make any difference for me though and neither does any other combination.

It would be very helpful to quantify the latency. What could help is a video with properly synced audio of the actual board.

My only guess is that we are processing MIDI interrupts at the wrong part of the frame on the PowerPC side leading to an extra frame of apparently latency. But if you think it is more than 16 or 32ms of latency (1-2 frames) then I don’t know.

The weird thing is in this video there is no sound delay or REALL REAYLLY smal that is also using the Model 3 emulator:

But I also have this problem with the Model 2 emulator.

So not everyone has this problem. I would be very curious what that is and what is causing the problem.
I will install the emulator on a friends PC which has a totallly different build than mine and see what happens.
I use a I9 10900K 3090 RTX 32GB DDR4

He uses:
i5 7th gen 1060 GTX 20 DDR4

What's your audio set up? Wired speakers via motherboard audio output?

I'm not very good at discerning audio latency but that video looks and sounds the same as VF3 on my PC. Just tried it. Could you make a video recording using FRAPS or Bandicam and see if the latency occurs there? If not, then a high quality cell phone video would be nice. I'd like to see if I can perceive the difference.

I will make a video with my cellphone (it's a samsung Note 20 Ultra) upcoming week!
My pc is connected with HDMI 2.0 cable to My Sony XH92 55inch TV which uses a Sonos Soundbar).

That would be great. Do you experience audio latency (or even input latency) with any other software? When I connect my laptop to TVs via HDMI, the latency is unbearable. A good test is playing Sonic the Hedgehog (Sonic Mania, for example). It's unplayable on a TV for me.

Some tvs have a 'game mode' specifically for low latency

My TV is on game mode I have a Sony XH92 Bravia so that is not the problem. Other games are good.
I will try to make a video next week when I have more time.
