Vsync on: sound is synced to video. Requires very exact sound timing (or bigger buffer)

Vsync off: sound and video is synced to 'clock'. "Sync" is quite relaxed, nobody notices if framerate isn't exactly 50fps, everyone notices if sound pops or breaks.

(Sync means "external" video/sound sync. Emulated program don't see any difference.)
Ok thanks, but how can i avoid the tearing issues with scrolling games? Vsync helps to do this.
I have a p4 2.8 ghz. Maybe Winuae requires much more power in order to get audio and video synched with Vsync enabled?
