MAME and Gsync/Freesync questions

[rparzial]

Hey There,

 

New to the forums, but not MAME. After 4 years of being away i am back with a new arcade cab and so much has changed. One of the main things being, i now have a Freesync monitor and now Nvidia cards with Freesync as well as Gsync. From what i understand this is amazing for MAME because it lets you run each game at its native framerate without tearing. 

I am just trying to figure out how all the settings should be for it to work right? I have a viewsonic XG2402 which says it needs to be in 144hz mode to use and activate freesync.

I assume i turn 144hz on in windows, turn 144hz on in the monitor OSD menu. Turn Gsync on in the Nvidia menu. And is that it? Does anything need to be configured with MAME itself (version 211)?

Also if the monitor is set to 144hz, does that mean games can run UP TO 144hz but also run at less hz if the game is pumping out a lower framerate? For example MAME uses many different framerates because each arcade was different. Thus each game running in MAME will send out its native framerate and the monitor set to 144hz will run at whatever speed MAME is telling it to?

Thanks so much for any advice,

Yeah, that should be it, Mame is pretty good with G-Sync out of the box. I've never had to adjust any settings for it and I have a G-Sync monitor.

Correct.

For a good quick test load up Samurai Shodown 2, get into a fight and look at the shadows on the ground. They should be flickering at a consistent rate giving the appearance of a shadow, if the shadow flicker is inconsistent it will be very noticeable. Another good test is Mortal Kombat, at the coin insert screen there will be scrolling characters on either side which should be a smooth scroll. Also after you select your fighter at the screen after where it scrolls down through all the fighters to the bottom should be smooth and not stutter.

NeoGeo and Mortal Kombat don't run at 60hz at all, they are closer to 54/55 or something close to that.

Thank you so much. I just turned everything on and it just worked. No messing around needed. Games look phenomenal. Definitely a worthy purchase. 

Really glad NVIDIA cards work with freesync now.

Good to hear you got it all sorted out, it really is nice playing those arcade games at their proper speeds without any weirdness like screen tearing or stutter.
