"Sync game to audio" creates motion sututtering (SVN945)

[Gobo]

Sure. Which settings should I use, the ones that cause the stuttering? default settings? if I have to go fullscreen, I'll only be able to see part of the results (once I go back to windowed mode) as the graph just keeps scrolling.

the graph will keep a log of average and max dpc.

This is a 5 min test for gbc game "Alice in Wonderland" under the offending settings. Attached is my current vba.ini.

[Squall Leonhart]

the stuttering happens because the fps drops to 50.

 

Disable AutoFrame skip. this appears to trigger a fps drop at random, The probability is that its not entirely compatible with the new audio core (like save states).

[Gobo]

Sorry but it was already disabled, check my vba.ini. Enabling it just worsens the stuttering.

[Squall Leonhart]

Im afraid i cannot reproduce this when auto frame skipping is enabled with vsync, vsync is enabled with audio sync, or throttle is used.

 

It only occurs as long as audio sync and auto frame limiting is used together for me.

 

was using super mario deluxe to verify.

On the other hand I've been able to reproduce the stuttering on 2 systems already. This just keeps getting weirder. What are your system specs?

[Squall Leonhart]

currently, an i7 920 @ 2.4-4Ghz.

[Squall Leonhart]

ok i have managed to reproduce it under OpenAL, but only when using hardware/software buffers.

 

the default XFI OAL device is low latency and doesn't cause it.

 

 

i still can't reproduce it on xaudio.

[Gobo]

For what it may be worth, my current sound driver won't do hardware buffers at all (hence my previous question) because it's optimized for low latencies and some nonessential features had to be left out.

 

Maybe it's my sound setup, but this is the first application to ever fall in conflict with it, assuming that's what's actually happening here.
