So What Cause's The Stuttering Sound Problem With DirectDraw??
Howard_Casto:
Yeah, the only way I can replicate the wierdness that mame is doing in my apps is if I turn off all scaling filters in d3d and scale an image below it's native resolution. In d3d scaling filters are not the same thing as blending filters. For something like mame it'd be a good idea to use one of the filters that uses complex math to scale.
Just on a side note... it seems odd to me that mame is locking the sound to the video refresh. Not that this isn't a good way to do it, but most lcd monitors, for example run at 60hz, so it seems like this stuttering would effect a lot of people, not just mame cab users.

Most lcd monitors run at 60hz? Don't know if I agree with that one. All 3 of mine run at 75hz. Maybe most did a few years ago, but I doubt it's the case now. Technology is always better than last time we check ;)
Andy: If Aaron doesn't address the scaling issues in Direct3d you raised, what about the idea of using the bezel files to add them in. I thought it was a good idea and probably not such a difficult program to write to generate them. But if it can be addressed at the source (pardon the pun), that would be a good thing. While I don't think it's a huge issue (I'm not a big fan of Pacman and other games with more noticable defects of missing "vertical columns of pixels") I appreciate that others might find it annoying and probably should be addressed.
Avrus:
The latest 118u2 of Mame allows incremental changes to throttling:

NOTE: If you are experiencing sound stuttering due to not being able
to run your display at >60Hz, please give the -speed option a try.
You should be able to run MAME at a small emulation speed decrease
in order to get the game under your monitor's refresh rate.

Now you guys can go back to arguing about pixels.
lettuce:
Is there an effects setting with in mame ( i know Aarons done a few) that sharpens up the image. As using D3D make the image blurry, maybe using a 'effect' that sharpens the image may counter act this blurryness??
8way:
Try "sharp". Not sure if this has changed in the latest build, but that’s it used to be.
