TLDR: Unlike the hefty price tag that usually accompanies G-Sync monitors, FreeSync is becoming a standard feature for a number of major brands like BenQ and LG. You’ll need an AMD card (R7 260 and above) to access FreeSync, but if you have an AMD GPU already, it’s worth taking advantage of it. If you’re running a Nvidia GPU instead, you should consider G-Sync instead.
If you’re a gamer, you’ve probably heard of Vsync. Basically, Vsync is a way for you to get rid of screen tearing in exchange for a small amount of input lag. Some people find the lag acceptable, others find it intolerable. Vsync works by limiting the frame rate to the refresh rate of your monitor, so if extra frames are rendered, they won’t be displayed and screen tearing will be reduced. FreeSync solves this problem as well as handling input lag associated with Vsync!
The way it works is simple. Normal monitors have a static refresh rate, typically in a range between 60 and 144hz. FreeSync is an adaptive sync technology, meaning it works with a dynamic refresh rate. By synchronizing the refresh rate of the display to the output of the GPU, stuttering and screen tearing can be eliminated entirely. Even if your FPS starts to chug, you’ll get a fluid gaming experience on your screen!
FreeSync doesn’t have a big price tag attached to it, so if you have an AMD card and you’re in the market for a monitor, it’s worth keeping your eyes out for it. Some people will find it critical, others won’t. With the upcoming release of FreeSync2, we’ll see this feature become more and more standard in the future.
