How do I configure MAME to use them? +-------------------------------------------------------------------------- + +MAME supports both G-Sync and FreeSync right out of the box for Windows and Linux, however macOS does not support G-Sync or FreeSync. + +* Make sure your monitor is capable of at least 120Hz G-Sync/FreeSync. If your monitor is only capable of 60Hz in G-Sync/FreeSync modes, you will hit problems with drivers such as *Pac-Man* that run at 60.60606Hz and may hit problems with others that are very close to but not quite 60Hz. +* If playing MAME windowed or using the BGFX video system, you'll need to make sure that you have G-Sync/FreeSync turned on for windowed applications as well as full screen in your video driver. +* Be sure to leave triple buffering turned off. +* Turning VSync on is suggested in general with G-Sync and FreeSync. +* Low Latency Mode will not affect MAME performance with G-Sync/FreeSync. + +The effects of G-Sync and FreeSync will be most noticeable in drivers that run at refresh rates that are very different from normal PC refresh rates. For instance, the first three *Mortal Kombat* titles run at 54.706841Hz.
