Ideally both drivers with a higher framerate and lower framerate than the screen would be tested to see the effects. I'd do the tests myself, but don't want to redo anything anyone else has already covered. MAMEDevs: any implementation differences between the video modes for vsync would be nice to know. I usually use D3D.

If you want to get real fancy, look into using a CRT. krick Get Fuzzy Reged: 02/09/04 Posts: 4235 Send PM Re: Vsync Study [Re: anikom15] #378428 - 09/03/18 12:46 AM Reply There's a bunch of research on input lag in the GroovyMAME forum. Here's two threads on the subject... http://forum.arcadecontrols.com/index.php/topic,133194.0.html http://forum.arcadecontrols.com/index.php/topic,157930.0.html GroovyMAME support forum on BYOAC anikom15 Instigator/Local CRT Guru Reged: 04/11/16 Posts: 287 Send PM Re: Vsync Study [Re: krick] #378445 - 09/04/18 05:00 AM Reply Thanks a lot, this will be a good start.

Then if you turn switchres and syncrefresh on in the ini, MAME can use these to play the games at screen speeds closer to the game hardware's intended. It'd be worth a longer discussion but in short from what I've seen and compared Groovy MAME is indeed better at this, it requires more configuration work though, and nothing being perfect in this world there are some limitations and little annoyances. Other advantage of note with Groovy is that you get -2 frames reduced lag by default using their d3d9ex build, which is faster than what any of the current normal MAME backends offer. Of course FreeSync or Gsync are easier and more accurate, but if you're broke trying your setup at switcheres+syncrefresh can yield great results too if you're lucky, maybe not 100% accurate but much better than forcing everything to 60Hz or enduring triplebuffer's choppiness. > MAME isn't about playing the games anyway.
