Title: seattle and vegas driver won't sync
Post by: haynor666 on January 23, 2015, 02:03:11 pm

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.

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

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.

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

I think we might have answer why there are such problems with syncrefresh - http://forum.arcadecontrols.com/index.php/topic,150279.msg1571041.html#msg1571041 (http://forum.arcadecontrols.com/index.php/topic,150279.msg1571041.html#msg1571041)

I'm unable to run Gauntlet Legends consistently at 100% on my 6700k@4GHz, in game it's at 100% but the speed oscillates a bit during transitions etc.

I used -triplebuffer -nowaitvsync -nosyncrefresh. Also did a quick test with standard MAME with gauntleg, and it seemed to perform similarly.

Edit:

I noticed the 199% speed thing as well on the 6700k, I have no idea what's going on. I also benchmarked the G3258, and it probably should be able to run the game at 100%, at least in gameplay, since it was able to run it above 100% speed consistently (see plot).

Edit again:

Regarding syncrefresh, try using -video d3d -nosyncrefresh -waitvsync, this worked for me. I was able to play through the first level without any noticeable drops!

Subject is really old but worth noticing that issue is still in mame 257.

Maybe someone found configuration in groovymame to make those games stable ?

I had to disable any kind synchronization in groovmame:

waitvsync 1
sync_mode 0
refreshspeed 0
syncrefresh 0
throttle 1

I think I know what happens with these games, will look into fixing it when I have some time.

(Basically these games perform bogus video updates, with empty data).
