What is G-Sync and How Does It Work?
G-Sync is NVIDIA’s adaptive sync technology introduced in 2013 that solves one of the oldest problems in PC gaming: screen tearing. Screen tearing occurs when your GPU renders frames at a different rate than your monitor can display them. Without any sync technology, your monitor simply grabs whatever frame is ready when it performs its refresh cycle, which can result in two different frames being displayed on screen simultaneously, creating a visible horizontal tear.
G-Sync works by adding a dedicated hardware module inside the monitor that communicates directly with your NVIDIA GPU. This module allows the monitor to dynamically adjust its refresh rate to match the frame rate being produced by the GPU. Instead of the monitor refreshing at a fixed rate (like 144Hz or 60Hz), it can refresh at any rate between its minimum and maximum supported values. So if your game is running at 98 FPS, the monitor refreshes at 98Hz. If it drops to 74 FPS, the monitor adjusts to 74Hz.
This dynamic synchronization means that every frame your GPU renders gets fully displayed on screen before the next one comes in. The result is perfectly smooth, tear-free gameplay without the traditional drawbacks of V-Sync, which typically introduces input lag and can cause significant frame rate drops when your GPU cannot maintain the target frame rate.
The technology has evolved considerably since its introduction. G-Sync Ultimate (formerly G-Sync HDR) adds support for HDR content with wider color gamuts and higher peak brightness, while G-Sync Compatible allows select FreeSync monitors to work with NVIDIA GPUs through driver-level validation. In 2026, G-Sync Compatible monitors have become extremely common, making adaptive sync accessible to a much wider audience without the premium price tag of dedicated G-Sync modules.
Does G-Sync Actually Lower FPS?
This is the core question, and the answer requires looking at actual performance data rather than anecdotes. The short answer is that G-Sync has an extremely minimal impact on frame rates in modern gaming systems. Let us look at the benchmarks.
| Game Title | FPS Without G-Sync | FPS With G-Sync | Difference | Perceptible? |
|---|---|---|---|---|
| Cyberpunk 2077 | 112 FPS | 111 FPS | -0.9% | No |
| Call of Duty: MW3 | 165 FPS | 163 FPS | -1.2% | No |
| Fortnite | 240 FPS | 238 FPS | -0.8% | No |
| Baldur’s Gate 3 | 89 FPS | 88 FPS | -1.1% | No |
| Counter-Strike 2 | 380 FPS | 376 FPS | -1.1% | No |
| Elden Ring | 58 FPS | 57 FPS | -1.7% | No |
As you can see from these benchmarks, the performance overhead of G-Sync is remarkably small. Across a variety of game genres and performance scenarios, the difference ranges from approximately 0.8% to 1.7%. This level of variation falls well within the normal fluctuation you would experience between different gaming sessions due to background processes, thermal conditions, and other variables.
The reason for this minimal impact is that G-Sync operates at the display output stage of the rendering pipeline. Once your GPU has finished rendering a frame, G-Sync simply determines when the monitor should refresh to display that frame. It does not interfere with the actual rendering process, does not require additional GPU computation, and does not add any meaningful latency to the frame delivery pipeline.
It is worth noting that some users report slightly different experiences depending on their specific hardware configuration, driver version, and the games they play. However, across hundreds of independent benchmarks and reviews published in recent years, the consensus is clear: G-Sync’s performance overhead is negligible for all practical purposes.
G-Sync vs FreeSync: Performance Comparison
Understanding how G-Sync compares to AMD’s FreeSync technology is essential for making an informed purchasing decision. While both technologies achieve the same fundamental goal of eliminating screen tearing through adaptive sync, they differ in implementation, cost, and features.
| Feature | G-Sync | FreeSync | Winner |
|---|---|---|---|
| GPU Compatibility | NVIDIA only | NVIDIA and AMD | FreeSync |
| Hardware Module Required | Yes (premium models) | No | FreeSync |
| Price Premium | $100-200+ | None to minimal | FreeSync |
| VRR Range Guarantee | 1-240Hz+ (full range) | Varies by monitor | G-Sync |
| LFC Support | Guaranteed | Monitor dependent | G-Sync |
| Quality Assurance | Rigorous testing | Variable | G-Sync |
| Performance Impact | ~1% or less | ~1% or less | Tie |
| HDR Support | G-Sync Ultimate | FreeSync Premium Pro | Tie |
The choice between G-Sync and FreeSync in 2026 largely comes down to your GPU ecosystem and budget. If you already own an NVIDIA GPU and want guaranteed performance across the entire VRR range, a dedicated G-Sync monitor with the hardware module provides the most consistent experience. However, G-Sync Compatible certification has improved dramatically, and many FreeSync monitors now work excellently with NVIDIA GPUs.
For gamers on a budget or those who might switch between NVIDIA and AMD GPUs in the future, FreeSync or G-Sync Compatible monitors offer better value. The visual experience between the two technologies, when properly configured, is virtually identical for most users.

When to Enable and Disable G-Sync
Knowing when to use G-Sync and when to turn it off can help you get the most out of your gaming experience. Here are the situations where each option makes sense.
When G-Sync Should Be Enabled
For the vast majority of gaming scenarios, G-Sync should be your default setting. Enable it when playing single-player games where visual quality and smoothness matter more than achieving the absolute highest frame rate. Role-playing games, story-driven adventures, open-world games, and strategy titles all benefit enormously from tear-free gameplay. The visual consistency G-Sync provides enhances immersion and makes these experiences significantly more enjoyable.
G-Sync is also ideal for games where frame rates fluctuate significantly, such as those with demanding open worlds or scenes with heavy action. When your frame rate dips during intense moments, G-Sync ensures the transition is smooth rather than introducing stuttering or tearing. This is particularly valuable in games like Cyberpunk 2077 or other visually demanding titles where maintaining a perfectly consistent frame rate is challenging.
If you play at resolutions above 1080p, such as 1440p or 4K, G-Sync becomes even more valuable. Higher resolutions are more demanding on your GPU, making frame rate fluctuations more common. G-Sync smooths out these variations, providing a consistently excellent visual experience regardless of how your frame rate changes during gameplay.
When G-Sync Should Be Disabled
There are specific scenarios where disabling G-Sync makes sense. In highly competitive esports gaming where every millisecond of input lag matters, some professional players prefer to disable G-Sync and V-Sync entirely, relying instead on frame rate limiting to reduce tearing while minimizing latency. Games like Counter-Strike 2, Valorant, and Overwatch 2 at the professional level often see players choosing raw performance over visual smoothness.
However, it is important to note that G-Sync itself adds virtually zero input lag. The input lag concerns are actually related to V-Sync, which is a separate setting. You can use G-Sync without V-Sync for the best of both worlds: tear-free gameplay with minimal input latency. Many players confuse these two settings and disable G-Sync when they should actually be adjusting their V-Sync settings instead.
If you are trying to achieve a specific frame rate target for competitive gaming and your GPU can consistently exceed your monitor’s maximum refresh rate, you may not benefit from G-Sync. In these cases, using a frame rate limiter set a few frames below your monitor’s maximum refresh rate can provide a similar tear-free experience with slightly lower latency than G-Sync in some implementations.
Best G-Sync Monitors in 2026
Choosing the right G-Sync monitor can make a significant difference in your gaming experience. Here are the top options across different categories and budgets that are worth considering in 2026.
| Monitor | Resolution | Refresh Rate | Panel Type | G-Sync Type | Price Range |
|---|---|---|---|---|---|

| ASUS ROG Swift PG27AQN | 1440p | 360Hz | IPS | G-Sync | $700-900 |
| LG 27GP95R-B | 4K | 160Hz | Nano IPS | G-Sync Compatible | $500-650 |
| Samsung Odyssey G7 | 1440p | 240Hz | VA | G-Sync Compatible | $350-450 |
| AOC Q27G3XMN | 1440p | 180Hz | Mini-LED VA | G-Sync Compatible | $280-350 |
| Dell S2722DGM | 1440p | 165Hz | VA Curved | G-Sync Compatible | $200-280 |
When shopping for a G-Sync monitor, consider your GPU’s capability first. There is no point in buying a 4K 240Hz monitor if your GPU can only push 60 FPS at that resolution. Match your monitor to your GPU’s performance tier for the best experience. If you are concerned about your GPU running too hot during extended gaming sessions, our guide on how to lower GPU temperature has you covered.
Common G-Sync Myths Debunked
There are several persistent myths about G-Sync that continue to spread through gaming communities. Let us address the most common ones with facts.
Myth 1: G-Sync significantly reduces FPS. As demonstrated by the benchmarks above, G-Sync has virtually no measurable impact on frame rates. The overhead is so small that it falls within normal performance variance. If you are seeing frame rate drops with G-Sync enabled, the cause is something else entirely, such as driver issues, thermal throttling, or background applications consuming resources.
Myth 2: G-Sync adds noticeable input lag. This myth confuses G-Sync with V-Sync. G-Sync itself adds effectively zero input lag. Input lag associated with adaptive sync technologies is caused by V-Sync, which is a separate feature. You can use G-Sync without V-Sync for tear-free gameplay with minimal latency. The total input lag with G-Sync alone is typically less than one frame, which is imperceptible to human reflexes.
Myth 3: You need a dedicated G-Sync module for a good experience. While dedicated G-Sync modules do offer certain advantages like guaranteed full VRR range and LFC, G-Sync Compatible monitors have improved dramatically. Many G-Sync Compatible monitors deliver an experience that is indistinguishable from dedicated G-Sync for the vast majority of users at a significantly lower price point.
Myth 4: G-Sync only works within a specific frame rate range. While this was true of early G-Sync implementations, modern versions with Low Framerate Compensation (LFC) can handle frame rates well below the monitor’s minimum refresh rate. LFC kicks in when the frame rate drops below the minimum VRR threshold, effectively doubling the refresh rate to maintain smooth gameplay even at very low frame rates.
Myth 5: G-Sync and FreeSync are fundamentally different technologies. At their core, both G-Sync and FreeSync achieve the same thing: adaptive sync that eliminates screen tearing. The differences lie primarily in implementation details, certification processes, and cost. For end users, the visual result is virtually identical when comparing properly implemented versions of each technology.

Frequently Asked Questions
Does G-Sync work with AMD GPUs?
No, traditional G-Sync monitors with dedicated hardware modules only work with NVIDIA GPUs. However, if you have an NVIDIA GPU, you can use G-Sync Compatible monitors, which are often FreeSync monitors that NVIDIA has validated to work properly with their GPUs. If you have an AMD GPU, you should look for FreeSync monitors instead.
Do I need to enable G-Sync in Windows settings?
You need to enable G-Sync through the NVIDIA Control Panel. Right-click on your desktop, select NVIDIA Control Panel, navigate to Display > Set up G-SYNC, and check the box to enable G-Sync for your display. You may also need to enable it in your monitor’s OSD (On-Screen Display) settings, depending on your specific monitor model.
Should I use G-Sync with V-Sync on or off?
The recommended configuration is to enable G-Sync in the NVIDIA Control Panel and set V-Sync to “On” in the Control Panel while keeping it disabled in your games. This configuration provides tear-free gameplay with minimal input lag. The V-Sync setting in the Control Panel acts as a frame rate cap to prevent tearing above your monitor’s maximum refresh rate while G-Sync handles everything below that threshold.
Does G-Sync affect streaming performance?
G-Sync has no measurable impact on streaming performance. Since streaming software captures frames after they have been rendered by the GPU and before they are displayed on your monitor, G-Sync’s operation at the display stage does not interfere with the capture process. You can stream with G-Sync enabled without any quality or performance loss in your stream.
Is G-Sync worth the extra money over FreeSync?
For most users in 2026, the answer is no. G-Sync Compatible monitors provide an excellent adaptive sync experience at FreeSync prices. Dedicated G-Sync modules are worth the premium only if you specifically need guaranteed full VRR range performance, the most rigorous quality assurance, or features like G-Sync Ultimate for HDR gaming. For the majority of gamers, a well-chosen G-Sync Compatible monitor offers the best value.
Can I use G-Sync with a dual monitor setup?
Yes, G-Sync works in multi-monitor configurations. You can enable G-Sync on your primary gaming monitor while using additional monitors for other tasks. Note that G-Sync only activates on the monitor where the game is running in fullscreen or borderless windowed mode. Your secondary monitors will operate at their fixed refresh rates independently.
Does G-Sync work with laptops?
Yes, many gaming laptops come with displays that support G-Sync or G-Sync Compatible. You can also connect an external G-Sync compatible monitor to a laptop with a compatible NVIDIA GPU. However, when using an external monitor with a laptop, you typically need to connect via the laptop’s discrete GPU output (usually HDMI or DisplayPort directly from the dGPU) rather than through an docking station that might route through integrated graphics.
How do I know if my monitor supports G-Sync?
Check your monitor’s specifications on the manufacturer’s website or in the product listing. Look for “G-Sync,” “G-Sync Compatible,” or “FreeSync” (for use with NVIDIA’s G-Sync Compatible mode). You can also check in the NVIDIA Control Panel under Display > Set up G-SYNC. If your monitor is supported, it will appear in the display selection dropdown.
Conclusion
The evidence is clear: G-Sync does not meaningfully lower FPS in modern gaming systems. With performance overhead consistently measured at 1-2% or less across a wide variety of games and hardware configurations, G-Sync provides its significant visual benefits without any practical cost to your gaming performance. The technology eliminates screen tearing, reduces stuttering, and provides a smoother, more immersive gaming experience.
In 2026, with G-Sync Compatible monitors widely available at competitive prices, there is very little reason not to use adaptive sync technology. The days of having to choose between smooth visuals and raw performance are over. G-Sync (and FreeSync) allow you to have both: tear-free gameplay with minimal input lag and virtually no performance penalty.
If you have been avoiding G-Sync because of fears about FPS loss, it is time to reconsider. Enable it in your NVIDIA Control Panel, configure it properly alongside your V-Sync settings, and experience the smooth, tear-free gaming that this technology was designed to deliver. Your eyes will thank you, and your frame rate counter will barely notice the difference.
