Title: Stopping Sound Stutter, With Triple Buffering, Wait For V Sync Enabled??
Post by: lettuce on July 31, 2007, 11:45:48 am

I have the latest version of mame 0.117u1 and am using ddraw mode, and have been getting alot of screen tearing. Enabling 'Triple Buffering' or 'Wait For V Sync' options stops the tearing but then make the music and sound skip within games. Is there a way to stop this from happening, ive got a gig of Ram and AMD 64 3200+ CPU, so i would have though that would of been plenty for running mame?, or is ithis an actual error with mame??

You will probably get an answer by posting here on mame.net:

They are pretty brutal on first time posters, so good luck.  You probably want to search that forum for answers prior to asking the question.

Quick answer:

The game ran at a different refresh rate than your monitor; thus the tearing.
Setting triple buffer or vsync plays the game at a different (refresh) rate than the sound is timed for, thus the sound problems.

IIRC, if you set the windows desktop refresh rate greater than the original game, this helps with the sound & triple buffer, but you'll get a screen repeated for two frames once in a while.

I don't mess with video settings much, though, so grain of salt.
