Performance and VSYNC

[RayB]

I've noticed that I can get alot of games that running poorly (20/60, 40/60 etc) to go full frame rate if I turn off WAITVSYNC.

Unfortunately, that of course causes "tears" in scrolling games. I didn't think it would bother me, but boy is that tearing noticable when you're using an arcade monitor!

I'm using a 1ghz with AVGA. Anyone have any advice on settings that affect performance the most? I already have Scanlines off, and I think Stretch is off. Triplebuffer is off.

Can you post your mame.ini file?  It would make it a lot easier.

(Can't remember if you are still using DMAME or not, so post whatever the appropriate file is and can you mention the OS)

Try triplebuffer instead.

Sorry I keep forgetting... DMAME 0.78

I'm not a DMAME guy, but here's a few things.  Also, what games are you having trouble with as some may just not be possible at 1Ghz.

-Artwork will slow things down
-Not sure if your monitor supports the lower resolutions, but the tweak modes are suppose to speed things up
-Is waitvsync valid? It's not in the DMAME txt, but that may be out of date.  There seems to be another command that does the same thing.
- Frameskip none may help
- Minwah's suggestion of triple buffer will help the scrolling
-Changing the Sample Rate may help

You are going to have to do testing with different games to find the settings you like the best.
