seattle and vegas driver won't sync

(1/3) > >>

haynor666:
My Arcade PC has now enough power to run some seattle and vegas games at 100 % stable but both groovymame and standard mame won't sync with waitvsync and/or syncrefresh. Those game always run at maximum speed or about 199%. This happen on G3258 with Radeon 4350 and 4670k with GTX770. Setting ddraw and triplebuffer does not help either. I can run those games with throttle but then tearing is visible.

Calamity:
What's the native refresh of those games? Please get a log when possible.

Gauntlet Dark Legacy: initial 640x480@57 but hardware changes to 511x384@60,386. GM picks 704x480@60,386.
CarnEvil: initial 640x480@57 but hardware changes to 399x256@54,123. GM picks 400x256@54,124

Calamity:
Yeah, there are speed issues with the Carnevil game, search this forum and you'll find some reports. I confirmed this too. But I don't know what's the possible reason. Not related to ATI drivers anyway. Need to check official MAME too.

haynor666:
Official MAME works almost the same way. Unthrottled and no synced all the time.
