When it comes to stuttering, FreeSync is considered to be lower in quality than G-Sync as in the past few years many gamers have voiced their complaints that FreeSync doesn’t work properly at higher FPS, for example, 120 FPS. Some have even complained that while running graphics-heavy games like Far Cry 4 at max settings there was considerable stuttering even at 60-70 FPS. Stuttering also depends partially on your monitor’s refresh rate, for example, if you’re using a monitor with a considerably low refresh rate and running games at extremely high frame rates then there will be stuttering and input lag regardless of whether or not FreeSync is enabled. So, the bottom line is, that stuttering is only caused occasionally by FreeSync and for the most part the syncing technology allows you to run games at higher FPS than you would normally.
