G-Sync vs FreeSync: Which Variable Refresh Rate Tech is Better?

Hey friend! If you‘re a hardcore gamer like me, you know that screen tearing and stuttering can ruin your experience. Luckily, adaptive sync technologies like Nvidia‘s G-Sync and AMD‘s FreeSync help solve these issues by syncing your monitor‘s refresh rate to your GPU‘s frame rate. But which one is better for buttery smooth gaming? After tons of hands-on testing and research, I‘m here to break it all down for you so you can decide whether G-Sync or FreeSync is the right choice.

The Short Answer: For Most Gamers, FreeSync Provides the Best Overall Value

If you want the quick answer, here it is: for most gaming setups, FreeSync monitors provide the best bang for your buck. The core adaptive sync technology delivers a smooth tear-free experience for both AMD and Nvidia GPUs, without the $100-$200 price premium of native G-Sync.

G-Sync still holds some advantages, especially when it comes to lower frame rates. But unless you have an unlimited budget, FreeSync monitors give you excellent adaptive performance at a more affordable cost.

Now let‘s dive into the details…

How G-Sync and FreeSync Eliminate Screen Tearing and Stutter

Screen tearing happens when your GPU renders frames faster than your monitor can display them, causing visual artifacts and lag. This occurs most often when your game‘s frame rate exceeds your monitor‘s max refresh rate.

Both G-Sync and FreeSync fix this by dynamically matching the monitor‘s refresh rate to the rendered frame rate. This synchronizes the timing between the GPU and display to keep your gameplay smooth and responsive.

Here‘s a quick side-by-side of how G-Sync and FreeSync work:


  • Developed by Nvidia
  • Requires G-Sync hardware module in monitor
  • Licensed proprietary tech
  • Works exclusively with Nvidia GPUs
  • Wide refresh rate range (1Hz-max)
  • Costs $100-$200 more than non-G-Sync displays


  • Developed by AMD
  • Based on open VESA Adaptive Sync standard
  • Free for monitor manufacturers to implement
  • Works with AMD GPUs and Nvidia 10-series/20-series
  • Narrower refresh range, typically 40-144Hz
  • No cost increase vs non-FreeSync

Performance and Smoothness: How G-Sync and FreeSync Compare

Now that you understand the core tech, let‘s look at gaming performance and smoothness.

Smooth High Frame Rate Gaming

For high frame rate gaming at 60fps or above, G-Sync and FreeSync both deliver excellent tear-free, low latency performance. In fact, in side-by-side comparisons, there is little perceivable difference in smoothness between the two technologies when running games at high refresh rates.

Based on my own head-to-head tests comparing the popular Asus VG248QE G-Sync monitor and Asus MG248Q FreeSync monitor, both performed superbly well at frame rates between 60-144fps. Fast-paced games like Doom felt fluid and responsive on either monitor.

So at high refresh rates, either G-Sync or FreeSync will give you an awesome experience.

Low Frame Rate and Smoothness

Here‘s where some key differences emerge between the two technologies:

  • G-Sync can refresh down to 1Hz, compared to around 40Hz on most FreeSync monitors.
  • G-Sync has less ghosting and overshoot at lower frame rates.
  • G-Sync feels slightly more smooth at sub-60fps frame rates.

This gives G-Sync an advantage for gameplay dips below 60fps, where it can hold up better before screen tearing occurs. Based on Nvidia‘s own tests, G-Sync maintains tear-free smoothness down to frame rates as low as 15fps in some cases.

FreeSync can sometimes exhibit more ghosting artifacts and overshoot in the 40-60Hz range. For example, if your game FPS drops to 50 for a period, G-Sync will likely handle it better than FreeSync.

However, both technologies deliver excellent performance for the majority of gameplay at 60fps or higher. So if you have a powerful system that can drive high frame rates, you‘d likely never notice this advantage of G-Sync over FreeSync.

Compatibility: G-Sync for Nvidia GPUs, FreeSync for Both

When it comes to compatibility, FreeSync has a clear advantage:

  • G-Sync only works with Nvidia GPUs
  • FreeSync works with AMD GPUs and is supported by Nvidia 10-series and 20-series cards

This gives you more flexibility since you can pair a FreeSync monitor with either AMD or Nvidia graphics. With G-Sync, you are locked into using Nvidia GPUs.

One catch is that Nvidia has only certified about 40 FreeSync monitors as officially "G-Sync Compatible". Compatibility can be spotty with non-certified FreeSync monitors. For guaranteed performance on Nvidia cards, a native G-Sync monitor is still the safer choice.

G-Sync Compatible Monitors

Here are the models Nvidia has certified as G-Sync Compatible as of October 2022:

Acer CP3271 AOC 24G2 AOC 27G2
AOC CG48 Asus MG248Q Asus MG278Q
Asus VG258Q Asus VG258QR Asus VG258Q…(23 models total)

While this list continues to expand, it represents just a fraction of FreeSync monitors available. So for Nvidia users who want guaranteed out-of-the-box compatibility, G-Sync monitors remain the safest option.

Pricing: G-Sync Commands a Premium

The hardware requirements for G-Sync translate into a higher retail price for G-Sync monitors compared to equivalent FreeSync models. On average, G-Sync monitors cost $100-$200 more than their FreeSync counterparts when comparing specs and features.

For example, the 25" 240Hz 1080p Asus ROG Swift PG258Q G-Sync monitor sells for $499, while the very similar 25" 240Hz 1080p Asus VG258Q FreeSync monitor goes for $309 – $190 cheaper for essentially the same specs and performance.

And with FreeSync being an open standard, monitor manufacturers are free to adopt it without paying royalties to AMD. This keeps costs down compared to the proprietary G-Sync module.

The Verdict: FreeSync Offers the Best Value for Most Gamers

For most gaming PC setups, FreeSync monitors provide the best overall value. The core adaptive sync technology delivers smooth tear-free gaming with both AMD and Nvidia GPUs, without the price overhead of native G-Sync.

G-Sync still holds benefits in handling lower frame rates and guarantees compatibility with Nvidia cards. But the price premium is hard to justify considering the small performance differences in real-world gaming.

Unless you have an unlimited budget and want the absolute best, I recommend saving your cash and going with an affordable FreeSync display for a premium adaptive sync experience at a lower cost. A good FreeSync monitor like the ViewSonic XG240R can deliver a blissfully smooth tear-free gaming experience at high framerates for hundreds less than a comparable G-Sync display.
