Wondering should vsync be on or off when gaming? The right setting depends on your monitor, graphics performance, and if you notice screen tearing or input lag.
VSync, or vertical synchronization, can help match your game’s frame rate with your monitor’s refresh rate, creating a smoother and cleaner image.
However, turning it on can sometimes introduce additional input latency or limit your frame rate.
In this guide, you shall learn what VSync does, when you should enable or disable it, and how each option affects gaming performance, responsiveness, and visual quality.
We shall also cover common mistakes and practical settings for different gaming situations, so you can choose the option that works best for your system.
Featured Snippet
VSync should be on if you want to eliminate screen tearing and your monitor has a fixed refresh rate.
Turn it off if you prioritize the lowest possible input latency and can tolerate tearing.
If you use G SYNC or FreeSync, the ideal settings depend on your VRR setup, but a frame rate cap is often recommended.

The Most Important Point
There is no universally correct VSync setting.
VSync On and VSync Off are both valid choices. The right option depends on what you value most:
- No screen tearing: Turn VSync on.
- Lowest possible input latency: Usually turn VSync off.
- Competitive gaming: VSync is often disabled when latency is the priority.
- Single player gaming: VSync can be useful if tearing is distracting.
- G SYNC or FreeSync: Use a VRR appropriate configuration rather than treating ordinary VSync rules as universal.
What Is VSync?
VSync, or vertical synchronization, is a graphics technology that synchronizes a game’s frame presentation with the monitor’s refresh cycle.
To understand why this matters, imagine a monitor refreshing at 60 Hz. It can refresh its image 60 times per second.
Now imagine your graphics card is rendering a game at 100 FPS.
The GPU may produce a new frame while the monitor is still displaying the previous frame. If portions of two different frames appear during the same refresh, you can see a visible horizontal split across the image.
That effect is called screen tearing.
VSync attempts to prevent this by controlling when frames are presented to the display.
What Does VSync Stand For?
VSync stands for vertical synchronization.
The term describes synchronization between the game’s frame output and the monitor’s vertical refresh cycle.
Although people often discuss VSync as an “FPS setting,” its primary purpose is synchronization and tear reduction, not increasing graphical performance.
What Happens When VSync Is On?
When VSync is enabled, the game attempts to synchronize frame presentation with the display’s refresh rate.
For example, with a 60 Hz monitor, traditional VSync may synchronize output around 60 FPS when the system can maintain that rate.
This can produce a cleaner image because the GPU is less likely to present frames at inappropriate points in the display’s refresh cycle.
Benefits of VSync On
1. It reduces screen tearing
This is the biggest reason to use VSync. Fast camera movements can look much cleaner when the display and GPU remain synchronized.
2. It can make gameplay look more visually consistent
When your system can maintain the appropriate frame rate, synchronized output can create a more orderly presentation.
3. It can prevent the GPU from rendering unnecessary frames
Depending on the game and implementation, VSync can prevent the GPU from rendering substantially more frames than the display can show.
4. It works well for many single player games
If you are playing a slower paced adventure, strategy, simulation, or RPG and tearing bothers you, VSync can be a sensible choice.
Potential Problems With VSync On
VSync is not free from disadvantages.
Input latency can increase. The exact amount depends on the implementation, frame rate, game engine, buffering method, and hardware.
Traditional VSync can also behave poorly when the GPU cannot consistently maintain the monitor’s refresh rate.
For example, if a game runs close to 60 FPS but repeatedly falls below 60 FPS on a 60 Hz display, traditional VSync may produce noticeable stutter or frame rate behavior that feels less smooth.
What Happens When VSync Is Off?
With VSync disabled, the GPU can generally present frames without waiting for traditional vertical synchronization.
This gives the graphics card greater freedom to render and present frames as quickly as possible.
If your GPU is producing 150 FPS on a 144 Hz monitor, for example, those frames are not being restricted by traditional VSync.
Benefits of VSync Off
1. Lower potential input latency
For competitive players, this is often the most important advantage.
A higher and less restricted frame rate can reduce the time between input and the display of a newer rendered frame, although actual latency depends on the entire system.
2. Higher FPS is possible
VSync itself does not increase performance. Disabling it simply removes the traditional synchronization limit.
Your actual FPS still depends on your GPU, CPU, game settings, resolution, and other factors.
3. Better for competitive gaming in many situations
Games such as competitive shooters often reward quick reactions. Players may prefer VSync off because they want the lowest practical latency.
Disadvantages of VSync Off
The biggest drawback is screen tearing.
If your GPU produces frames at a rate that does not align with your monitor’s refresh cycle, portions of different frames may become visible during one refresh.
You may notice this especially during:
- Fast camera movements
- Horizontal panning
- Rapid turns
- Scrolling
- High FPS gameplay on fixed refresh monitors
Some players barely notice tearing. Others find it extremely distracting.
VSync On vs. Off: Key Differences
The simplest way to understand the choice is to think about image synchronization versus responsiveness.
Choose VSync On If:
- Screen tearing bothers you.
- You use a fixed refresh rate monitor.
- You mainly play single player games.
- You prefer a synchronized presentation.
- Your system can maintain your target refresh rate reasonably well.
- You are willing to accept potentially higher input latency.
Choose VSync Off If:
- You want the lowest possible latency.
- You play competitive games.
- Screen tearing does not bother you.
- You want your GPU to render without traditional VSync restrictions.
- Your system produces substantially more FPS than your monitor’s refresh rate.
- Responsiveness matters more to you than perfectly synchronized frames.
Should VSync Be On or Off for Gaming?
For most gamers, the answer depends on the type of gaming experience they want.
For Competitive FPS Games
VSync Off is usually the preferred starting point when minimizing input latency is the priority.
Competitive players often care more about rapid response than eliminating every instance of tearing.
However, if tearing is highly distracting, you may prefer a VRR solution such as G SYNC or FreeSync rather than simply accepting severe tearing.
For Single Player Games
VSync On can be a good choice if you notice screen tearing.
Story driven games, RPGs, adventure games, and other slower paced titles often benefit visually from a clean, tear free presentation.
If input latency is not bothering you, there may be little reason to disable VSync simply to chase a higher FPS number that your monitor cannot fully display.
For Racing Games
Racing games involve frequent horizontal movement and camera motion, making tearing particularly noticeable for some players.
If tearing appears along the road, scenery, or horizon, enabling VSync may improve visual consistency.
However, racing games can also benefit from low latency, so VRR is often an excellent alternative when supported.
For Strategy Games
For many strategy games, the difference between VSync on and off is less important than it is in competitive shooters.
If tearing bothers you, VSync on is reasonable. If you want maximum responsiveness and do not notice tearing, VSync off is also perfectly acceptable.
How Does Your Monitor’s Refresh Rate Affect VSync?
Your monitor’s refresh rate is extremely important.
A 60 Hz display refreshes 60 times per second.
A 120 Hz display refreshes 120 times per second.
A 144 Hz display refreshes 144 times per second.
A 240 Hz display refreshes 240 times per second.
Higher refresh rate monitors can display more frames per second, but they do not automatically eliminate screen tearing.
For example, a 144 Hz monitor can still experience tearing if frame presentation is not synchronized.
Example
Suppose your monitor is 144 Hz and your GPU renders 220 FPS.
With VSync off, the GPU can continue producing frames at that rate, but you may see tearing.
With traditional VSync on, frame presentation is synchronized with the display, potentially reducing tearing but potentially increasing latency.
This is why many modern gaming setups use variable refresh rate (VRR) technologies instead.
What Is VRR, and How Is It Different From VSync?
Variable refresh rate (VRR) allows the monitor to dynamically change its refresh rate to match the frame rate being produced by the GPU within the display’s supported range.
Two major VRR technologies are:
- NVIDIA G SYNC
- AMD FreeSync
Traditional VSync generally works by synchronizing frame presentation to a fixed display refresh cycle.
VRR takes a different approach: instead of forcing the GPU to conform to one fixed refresh rate, the display can adjust its refresh timing to the current frame rate.
Why VRR Can Be Better
Suppose your game fluctuates between 100 and 130 FPS.
On a suitable VRR monitor, the display can adjust its refresh behavior to follow those changing frame rates.
This can significantly reduce tearing while maintaining a responsive feel.
For many modern gaming PCs, VRR is preferable to relying solely on traditional VSync.
Should VSync Be On or Off With G SYNC?
This is where the simple “always turn VSync off” advice becomes incomplete.
With G SYNC, recommended configurations often use G SYNC together with VSync at the driver level and a frame rate cap below the monitor’s maximum refresh rate.
The purpose is not to use traditional VSync as the only synchronization technology. Instead, the settings work together to keep rendering within the VRR range and prevent the system from reaching the display’s maximum refresh boundary.
For example, on a 144 Hz G SYNC display, a commonly recommended approach is to cap the game below 144 FPS rather than allowing it to continually hit the maximum refresh rate.
The exact best configuration can vary by game, monitor, driver, and personal preference.
Should VSync Be On or Off With FreeSync?
FreeSync is AMD’s adaptive sync technology and serves a similar broad purpose to G SYNC: matching the display’s refresh behavior to changing frame rates.
If you have a FreeSync monitor, you should first make sure FreeSync is properly enabled and supported by your hardware and display.
Rather than simply asking if VSync should always be on or off, consider the entire configuration:
- FreeSync/VRR enabled
- Appropriate refresh rate selected
- Frame rate kept within the monitor’s VRR range
- Reasonable FPS cap when appropriate
- VSync configured according to the GPU driver’s recommended behavior and your latency preference
The ideal settings can differ between systems, so blanket advice such as “VSync must always be off with FreeSync” is too simplistic.
Does VSync Reduce FPS?
VSync can limit the frame rate to the display’s refresh behavior, but it does not directly make your GPU less powerful.
For example, if your GPU can render 200 FPS on a 60 Hz monitor, enabling traditional VSync may prevent the game from presenting those frames freely and instead synchronize output around the display’s refresh rate.
However, the precise behavior depends on the game’s VSync implementation.
It is also important to distinguish between:
- Rendering FPS
- Presented/displayed frames
- Monitor refresh rate
- Input latency
These are related, but they are not identical.
Does VSync Cause Input Lag?
VSync can increase input latency, particularly with traditional implementations and buffering behavior.
When synchronization requires the GPU or game engine to wait for an appropriate display interval, the latest input may take longer to appear on screen.
However, the amount of latency varies considerably.
It can depend on:
- GPU performance
- CPU performance
- Frame rate
- Refresh rate
- Game engine
- Driver behavior
- Buffering method
- VSync implementation
- Frame time consistency
Therefore, saying “VSync always causes huge input lag” is inaccurate.
A better statement is that traditional VSync can increase latency compared with an unrestricted configuration, especially when frame delivery is poorly matched to the display.
Does VSync Improve Graphics Quality?
VSync does not improve the resolution, textures, shadows, anti aliasing, or other fundamental graphics settings.
Its primary visual benefit is reducing screen tearing.
A game with VSync on does not necessarily have better graphical quality than the same game with VSync off.
Instead, the image may look cleaner during motion because the frames are synchronized more appropriately with the display.
Does VSync Improve Performance?
No.
VSync does not make your GPU or CPU faster.
If anything, enabling VSync can restrict frame presentation or introduce waiting behavior.
It can reduce unnecessary rendering in some situations, which may lower GPU utilization and power consumption, but that is different from increasing hardware performance.
If a game is running at 35 FPS, turning VSync on will not magically make it run at 60 FPS.
For higher performance, you need to address factors such as:
- Resolution
- Graphics quality
- Ray tracing
- Texture settings
- Shadows
- CPU limitations
- GPU limitations
- Background applications
- Upscaling technologies
VSync and Frame Rate Caps
A frame rate cap can be extremely useful in modern gaming.
Instead of allowing the GPU to render as many frames as possible, you can set a maximum FPS.
For example, on a 144 Hz display, you might use a frame rate limit below 144 FPS when using a VRR configuration.
The exact number depends on the monitor and configuration.
A frame cap can help:
- Keep FPS inside the VRR range
- Reduce unnecessary GPU workload
- Improve frame time consistency
- Reduce heat and power consumption
- Prevent the GPU from constantly pushing maximum FPS
For competitive players, the ideal cap may differ because they may prioritize latency over efficiency.
Common VSync Mistakes
Mistake 1: Thinking VSync Is a Performance Booster
Incorrect:
“VSync makes my computer run games faster.”
Correct:
“VSync synchronizes frame presentation with the display and can reduce screen tearing.”
VSync is not a performance upgrade.
Mistake 2: Assuming VSync Always Causes Severe Lag
Incorrect:
“VSync always makes every game lag badly.”
Correct:
“Traditional VSync can increase input latency, but the effect varies by implementation and system.”
Mistake 3: Assuming VSync Off Is Always Better
Incorrect:
“Everyone should turn VSync off.”
Correct:
“VSync off can be preferable for latency sensitive gaming, but VSync on may be better if tearing is distracting.”
Mistake 4: Ignoring VRR
A common mistake is comparing VSync on and off without considering G SYNC or FreeSync.
If your monitor supports VRR, your best configuration may be different from a traditional fixed refresh monitor.
Mistake 5: Confusing FPS With Refresh Rate
A monitor’s refresh rate is measured in Hz, while game frame output is commonly measured in FPS.
They describe different things.
A 144 Hz monitor can refresh up to 144 times per second, while a game might render 90, 144, 200, or another number of frames per second.

When Should You Use VSync?
Academic Writing
In technical or academic writing, use VSync when discussing the technology itself.
Example:
“VSync synchronizes frame presentation with a display’s refresh cycle to reduce screen tearing.”
Avoid treating VSync as an ordinary English word that needs grammatical variation.
Professional Writing
In professional technical documentation, define the abbreviation the first time it appears:
Vertical synchronization (VSync) can reduce visible screen tearing.
Afterward, simply use VSync.
Formal English
Use precise terminology:
- VSync enabled
- VSync disabled
- VSync is on
- VSync is off
- vertical synchronization
Avoid vague statements such as “VSync makes graphics better.”
Business Writing
If discussing software, hardware, or game development, explain the effect rather than assuming the reader understands the term.
For example:
“Enabling VSync may reduce screen tearing but can affect input latency and frame presentation.”
Emails
A concise technical email might say:
“Could you test the application with VSync enabled and disabled? I want to determine if the visual tearing is related to frame synchronization.”
Daily Conversation
Gamers commonly say:
- “VSync is on.”
- “Turn VSync off.”
- “Does VSync add lag?”
- “VSync fixed my screen tearing.”
These are natural and grammatically correct uses.
American vs. British English: Is There Any Difference?
There is no meaningful American versus British English difference in the use of VSync.
The term refers to the same graphics technology in both varieties of English.
You may see differences in surrounding technical vocabulary, but VSync, vertical synchronization, screen tearing, frame rate, and refresh rate retain the same meanings.
For example:
American English:
“My monitor has a 144 Hz refresh rate.”
British English:
“My monitor has a 144 Hz refresh rate.”
The terminology remains essentially the same.
Easy Memory Trick: “On for Order, Off for Freedom”
Use this simple rule:
VSync ON = Order
Frames are synchronized more closely with the monitor.
Think:
ON → Organized → Less Tearing
VSync OFF = Freedom
The GPU is freer to render and present frames without traditional VSync restrictions.
Think:
OFF → Open → Lower Latency Potential
So remember:
VSync ON = prioritize a tear free image.
VSync OFF = prioritize unrestricted rendering and low latency.
This is a useful starting rule, not an absolute law. VRR changes the equation.

FAQs
Should VSync be on or off for gaming?
VSync should be on when eliminating screen tearing is your priority, especially on a fixed refresh monitor. Turn it off when minimizing input latency and allowing unrestricted frame rendering matter more. For competitive games, many players prefer VSync off, while single player gamers may prefer it on. VRR technologies such as G SYNC and FreeSync can change the ideal configuration.
Does VSync increase input lag?
Traditional VSync can increase input latency because frame presentation may wait for an appropriate display refresh interval. However, the actual effect varies depending on the game’s implementation, frame rate, buffering, drivers, and hardware. If responsiveness is your highest priority, disabling traditional VSync may reduce latency, although a VRR setup can provide a better balance between responsiveness and tear reduction.
Is VSync good for 60 Hz monitors?
VSync can be useful on a 60 Hz monitor because screen tearing can become noticeable when the GPU produces frames at a rate that does not align with the display’s refresh cycle. If tearing bothers you, enabling VSync is worth trying. If you play competitive games and strongly prioritize low latency, you may prefer VSync off.
Should VSync be on or off with G SYNC?
With G SYNC, the best configuration differs from traditional fixed refresh gaming. A commonly recommended setup uses G SYNC with appropriate VSync behavior and limits FPS below the monitor’s maximum refresh rate. This keeps the system within the variable refresh range while helping prevent the display from reaching its maximum refresh boundary. Exact settings can vary by hardware and preference.
Does turning VSync off increase FPS?
Turning VSync off can allow the GPU to render and present frames without the traditional synchronization limit, so the displayed FPS counter may rise. However, VSync does not determine your computer’s underlying rendering performance. Your maximum FPS still depends on your CPU, GPU, game settings, resolution, and the game’s workload. Higher reported FPS does not automatically mean a better visual experience.
Does VSync remove screen tearing?
VSync is specifically designed to reduce or eliminate traditional screen tearing by synchronizing frame presentation with the display’s refresh cycle. However, the result depends on the implementation and system configuration. Modern VRR technologies such as G SYNC and FreeSync can also reduce tearing while adapting the monitor’s refresh behavior to changing frame rates.
Key Takeaways
- VSync means vertical synchronization.
- Its main purpose is to reduce screen tearing.
- VSync On prioritizes synchronized frame presentation.
- VSync Off allows more unrestricted frame rendering.
- VSync can introduce additional input latency, depending on the implementation.
- Disabling VSync does not make your GPU inherently more powerful.
- A higher FPS number does not automatically mean better gaming.
- Competitive players often prefer VSync Off when minimizing latency.
- Single player gamers may prefer VSync On when tearing is distracting.
- A fixed refresh monitor and a VRR monitor should not necessarily use the same settings.
- G SYNC and FreeSync can provide a better balance between smoothness and responsiveness.
- Frame rate caps can be useful in modern VRR configurations.
- There is no single VSync setting that is best for every gamer.
Conclusion
So, should VSync be on or off? If screen tearing bothers you and you use a fixed refresh monitor, VSync On is usually a sensible choice.
If you play competitive games and want the lowest practical input latency, VSync Off is often preferable.
However, if your monitor supports G SYNC or FreeSync, consider the complete VRR configuration rather than relying on a simple on or off rule.
The best setting is ultimately the one that gives you the right balance of smoothness, tearing control, frame rate, and responsiveness for the games you play.
