VSync, or vertical synchronization, is a display technology that synchronizes your GPU’s frame output with your monitor’s refresh rate. Without it, you may experience screen tearing, which happens when the GPU sends frames faster than the monitor can display them. Choosing the right type of VSync can significantly affect your gaming experience.
Not all VSync implementations are equal. Some eliminate tearing while introducing input lag, others reduce stuttering, and a few do both well. Understanding the differences helps you make a smarter choice for your setup.
Quick Answer
The best type of VSync for most gamers is Adaptive Sync (G-Sync or FreeSync). It eliminates screen tearing without the input lag penalties of traditional VSync. If your GPU and monitor support it, Adaptive Sync is the clear winner. For those without compatible hardware, Fast Sync or Enhanced Sync are strong alternatives.
Key Takeaways
- Adaptive Sync (G-Sync/FreeSync) is the best overall VSync option for eliminating tearing with minimal input lag
- Traditional VSync caps your frame rate and introduces noticeable input lag
- Fast Sync (NVIDIA) and Enhanced Sync (AMD) are better alternatives to traditional VSync for high frame rate gaming
- Adaptive VSync is a middle-ground option that disables VSync when frame rates drop below refresh rate
- The best choice depends on your GPU brand, monitor type, and the games you play
- VSync is less necessary if your frame rate stays consistently above your monitor’s refresh rate
- Using the wrong VSync type can cause stuttering, lag, or wasted GPU performance
Types of VSync Explained
Traditional VSync
Traditional VSync is the original synchronization method, and it is the least recommended for most modern setups. It works by capping your frame rate to match your monitor’s refresh rate, typically 60Hz.
The major drawback is input lag. When your GPU cannot maintain the target frame rate, VSync drops to the next divisor, such as 30fps on a 60Hz monitor, causing noticeable stuttering. This makes it a poor choice for fast-paced games.
Adaptive VSync (NVIDIA)
Adaptive VSync is a smarter version of traditional VSync that turns synchronization on and off based on your frame rate. When your GPU exceeds your monitor’s refresh rate, VSync activates to prevent tearing. When it drops below, VSync disables to prevent stuttering.
This is a solid middle-ground option for players with mid-range hardware who experience inconsistent frame rates. It is better than traditional VSync but still rate gaming where your GPU consistently produces well above your monitor’s refresh rate.** Instead of locking frames, they use a triple buffering system to display the most recently completed frame, reducing tearing without the input lag of traditional VSync.
These options work best when your GPU runs at two to three times your monitor’s refresh rate. At lower frame rates, they offer little benefit and considered the best VSync solution available.** Rather than capping frames, they dynamically adjust the monitor’s refresh rate to match the GPU’s output in real time.
The result is a tear-free, stutter-free experience with virtually no added input lag. This is the gold standard for competitive and casual gaming alike.
VSync Type Comparison Table

| Fast Sync / Enhanced Sync | Mostly | Low | Low | High frame rate gaming |
| G-Sync / FreeSync | Yes | Very Low | Very Low | Most modern setups |
GPU Brand Compatibility Table
| Technology | GPU Brand | Monitor Requirement |
|---|---|---|
| G-Sync | NVIDIA | G-Sync or G-Sync Compatible monitor |
| FreeSync | AMD | FreeSync monitor |
| Fast Sync | NVIDIA | Any monitor |
| Enhanced Sync | AMD | Any monitor |
| Adaptive VSync | NVIDIA | Any monitor |
| Traditional VSync | Both | Any monitor |
When Should You Use Each Type?
Use G-Sync or FreeSync If:
- Your monitor supports Adaptive Sync
- You want the best balance of smoothness and responsiveness
- You play games with variable frame rates
If you are shopping for a new monitor and want to understand how display technology affects your experience, our guide on MSI monitors and ViewSonic monitors covers which models support Adaptive Sync.
Use Fast Sync or Enhanced Sync If:
- Your GPU consistently runs at very high frame rates
- Your monitor does not support Adaptive Sync
- You want low input lag without tearing
Avoid Traditional VSync If:
- You play competitive games where input lag matters
- Your GPU struggles to maintain your monitor’s refresh rate consistently

Common Misconceptions About VSync
Misconception: VSync always improves visual quality. In reality, traditional VSync can make games feel worse due to added input lag and stuttering when frame rates fluctuate.
Misconception: You always need VSync. If your frame rate is consistently below your monitor’s refresh rate, there is no tearing to fix, so VSync adds lag without benefit.
Misconception: G-Sync and FreeSync are the same. While both use Adaptive Sync, G-Sync uses proprietary NVIDIA hardware in the monitor, while FreeSync is an open standard. NVIDIA GPUs can now work with many FreeSync monitors through G-Sync Compatible certification.

Also worth noting: VSync behavior can vary depending on your connection type. If you are using HDMI, our dual monitor HDMI setup guide explains how cable choice can affect refresh rate and sync performance.
Conclusion
The best type of VSync depends on your hardware, but Adaptive Sync (G-Sync or FreeSync) is the top choice for most users. It solves tearing without the drawbacks of traditional VSync. If your monitor does not support Adaptive Sync, Fast Sync or Enhanced Sync are the next best options.
Understanding which VSync method matches your setup helps you get the smoothest, most responsive experience from your display without unnecessary compromise.
FAQs
What is the best VSync setting for gaming?
G-Sync or FreeSync is the best VSync setting for gaming. These Adaptive Sync technologies eliminate tearing and stuttering with minimal input lag, making them ideal for both competitive and casual play.
Does VSync cause input lag?
Traditional VSync does cause input lag, especially when frame rates drop below the monitor’s refresh rate. Modern alternatives like Fast Sync and Adaptive Sync technologies significantly reduce or eliminate this issue.
Should I turn VSync on or off for competitive gaming?
For competitive gaming, it is generally better to turn traditional VSync off and use G-Sync or FreeSync if available. These options reduce input lag while still preventing screen tearing.
Is G-Sync better than FreeSync?
G-Sync typically offers more consistent performance due to its dedicated hardware module, but FreeSync has improved significantly and performs comparably on most modern monitors. The best choice depends on your GPU brand.
Does VSync affect FPS?
Yes, traditional VSync caps your FPS to your monitor’s refresh rate. Adaptive Sync technologies do not cap FPS in the same way, allowing your GPU to run freely while the monitor adjusts to match.
Can I use G-Sync with an AMD GPU?
No, G-Sync is an NVIDIA-exclusive technology. AMD GPU users should use FreeSync monitors. However, NVIDIA GPU users can often use FreeSync monitors through G-Sync Compatible certification.
What happens if VSync is on but frame rate is low?
If your frame rate drops below your monitor’s refresh rate with traditional VSync enabled, the frame rate will stutter down to the next divisor, such as 30fps on a 60Hz display. Adaptive VSync or Adaptive Sync technologies handle this more gracefully.
