Understanding Refresh Rate: FreeSync Vs Gsync

Monitors with Adaptive sync technologies from AMD and Nvidia have been available in the market for a few years now. But recently among the gamer community, FreeSync Vs Gsync has been the talk of the town due to a wide variety of options now available.

The problem with a standard fixed rate 60Hz monitor is that it doesn’t refresh the frames generated by GPU with synchronization.

Because GPU renders frames with volatility, depending up on a particular scene in the game. Since the Frames per second output differs from the monitor’s refresh rate, it causes screen tearing.

Now tearing is annoying during gameplay because the monitor is trying to display two frames at the same time. Tearing is managed with a V-sync feature that holds the next rendered frame and tries to display them in a stack in sync with the monitor’s refresh rate. This eliminates tearing but introduces stuttering because the frame is only displayed when rendered and stacked together.

The solution, however, is with adaptive sync displays, which adapts its refresh rate according to the fluctuating frame rate of the GPU. This eliminates both stuttering and tearing and introduces clarity in image viewing. Both G-Sync (NVIDIA) and FreeSync (AMD) provide the key features of adaptive sync, but because of implementation differences, there are some other features as well.

G-Sync uses NVIDIA’s proprietary technology but continuously tweaking monitor overdrive to eliminate the ghosting effect. FreeSync monitors have also improved quite a lot with driver updates over the past few years.
G-Sync offers Ultra Low Motion Blur (ULMB) feature as well. That strobes backlight in sync with display’s refresh rate, to reduce the motion blur/ghosting effect at high-motion situations. At the cost of slightly low brightness.

Low Framerate Compensation (LFC) offered with G-Sync duplicates the shown frame rate making it a smoother visual experience while the refresh rate dynamically adjusts with the GPUs render rate.

FreeSync monitors have a different variety of monitors where some of them are gaming-focused but not towards everyday office usage. Also, some of the monitor’s do not offer LFC feature because of the limited Hz rate. Looking at near-identical monitors from both the brands, G-Sync adds an average of $180-$200 MSRP over the somewhat identical FreeSync model.
